ECG vs ECHO: Difference between an Echocardiogram and Electrocardiogram

In the complex realm of cardiac care, where every beat counts, healthcare experts rely on a vast array of diagnostic technologies to figure out the mysteries of the heart. Among these techniques, the electrocardiogram (ECG or EKG) and the echocardiogram (ECHO) stand out, each providing distinct insights into the complexity of how the heart functions. While both tests have the same purpose of measuring heart health, they do so from different perspectives, providing doctors with crucial information for diagnosis and treatment. In this blog, we will look into the subtle differences of the ECG and ECHO, understanding their roles, distinctions, and significance in cardiovascular care.


Electrocardiogram

An electrocardiogram (ECG/EKG) is a non-invasive test that evaluates the electrical activity of the heart. Here, electrodes are placed on the skin, usually on the chest, arms, and legs, to detect and record the electrical impulses produced by the heart as it beats. These impulses are then displayed as waves on a graph, revealing information about the heart's rhythm and pace.

 
Echocardiogram

Echocardiogram (ECHO) is a diagnostic imaging technique that uses sound waves to visualize the heart's anatomy and function. During an echocardiography, a transducer is placed on the chest and generates sound waves that bounce off the heart's tissues, resulting in images on a screen. This enables healthcare providers to see the heart chambers, valves, and blood flow patterns, revealing important information about the heart's size, shape, and overall function.

 
Types of electrocardiograms (ECG)

Resting ECG: A standard test performed when the heart is at rest to assess electrical activity.

Exercise Stress Test: Measures the heart's response to physical exertion on a treadmill or stationary bike.

Holter Monitoring: A portable device worn for 24-48 hours to record heart rate throughout daily activities.

Event Monitoring: Similar to Holter monitoring but worn for extended periods of time and activated by patients when experiencing symptoms.

 
Types of Echocardiograms (ECHOs)

Transthoracic echocardiogram (TTE): The most frequent form, which uses a transducer on the chest wall to see the heart's structure.

Transoesophageal Echocardiogram (TEE): A specialized procedure that uses a probe placed into the esophagus to get sharper pictures of certain tissues.

Doppler Echocardiogram: A Doppler ultrasound is used to evaluate blood flow throughout the heart and arteries.

Stress Echocardiogram: Combines echocardiography and stress induction to evaluate heart function and detect ischemia.

 
How are ECG and ECHO done?

The electrocardiogram (ECG) and echocardiography (Echo) are both important diagnostic techniques in cardiology, providing distinct insights into the heart's health. An ECG is performed by placing electrodes at certain spots on the chest, legs, and arms. These electrodes detect the electrical signals of the heart, which an ECG machine records as a series of waves on graph paper or a digital display. During the test, the patient is usually requested to lie down and stay still for a few minutes. A healthcare practitioner examines the ECG trace to determine heart rate, rhythm, and abnormalities such as arrhythmias or ischemia.

In contrast, an echocardiography begins with the application of gel to the chest to facilitate skin contact with a handheld device known as a transducer. The transducer produces high-frequency sound waves (ultrasound) that penetrate the chest and bounce off the heart structures, resulting in real-time images of the heart displayed on a monitor. The technician or cardiologist uses these images to evaluate the heart's size, shape, wall thickness, chamber dimensions, valve function, and blood flow patterns. The duration of the echocardiography varies depending on the type of examination (transthoracic or transoesophageal) and the amount of information required. Transoesophageal echocardiography (TEE) involves inserting a specialized probe into the esophagus to produce sharper images of the heart structures, which usually requires the patient to be sedated to reduce discomfort.

Both the ECG and the echocardiography are non-invasive, safe examinations that help diagnose various heart problems and guide therapy options. While an electrocardiogram (ECG) measures the electrical activity and rhythm of the heart, an echocardiography gives precise imaging of the heart's structure and function. Together, these tests contribute to a thorough assessment of cardiac health, allowing for the delivery of best patient care.

 
When do you need ECGs and ECHOs?

ECGs are common diagnostic methods used in the following situations:

  • When you have an irregular heartbeat (arrhythmia)
  • When you have a heart attack or chest pain as a symptom of coronary artery disease
  • If you've had a previous heart attack
  • To evaluate the efficacy of heart disease treatments like pacemakers.

 
You may require an ECHO in the following situations:

  • To ensure that there are no issues with the heart's valves or chambers.
  • To determine whether heart problems are the root of the problem or symptoms.
  • To detect congenital heart abnormalities before birth.

 
To summarize, while both electrocardiograms (ECGs) and echocardiograms (ECHOs) are useful diagnostic techniques for assessing heart health, they serve different functions and provide complementary information. An ECG primarily assesses the heart's electrical activity and rhythm, but an echocardiogram provides detailed information about the heart's structure, function, and blood flow dynamics.

Depending on the clinical situation, healthcare providers may use one or both tests to obtain a complete assessment of a patient's cardiac status. Understanding the distinctions between an ECG and an echocardiogram allows patients and healthcare professionals to make more informed decisions about cardiac testing and management techniques, ultimately leading to improved heart health outcomes.

Gas Pain and Heart Attack: Key Differences

Ever panicked because of a slight stabbing pain in your chest and have thought it to be a heart attack? Yes, everyone has had it. Gas and heart attack both cause chest pain. It’s quite common to experience pain in the chest after a heavy meal. It’s often due to digestive issues. About 70% of chest pain may be classified as noncardiac chest pain. 

Pain due to Gas:

Non-cardiac chest pain, commonly referred to as gas pain, arises from the accumulation of trapped air or gas within our digestive systems. The discomfort associated with gas-induced chest pain can manifest as sharp, stabbing, or cramp-like sensations. It is frequently accompanied by bloating and excessive belching. This type of chest pain is usually transient and alleviated by the release of gas through burping. Factors such as aerophagia, dyspepsia, and gastrointestinal conditions like acid reflux or irritable bowel syndrome (IBS) can exacerbate gas-related chest pain.

Heart Attack:

A heart attack occurs when there is a significant obstruction or restriction in the flow of blood to the heart muscle. This obstruction typically arises from the accumulation of fatty deposits, cholesterol plaques, and other substances within the coronary arteries, leading to a condition known as coronary artery disease (CAD). This constriction impedes the vital supply of oxygen and nutrients to the heart tissue, resulting in a heart attack.

Difference between Gas Pain and Heart Attack

Causes of Gas Pain:

Gas-induced pain may arise when gas accumulates in the stomach or the descending part of the colon. Various factors and behaviors can contribute to the retention of gas within the digestive system:

  1. Food intolerance
  2. Food poisoning
  3. Too much artificial sweeteners
  4. Excess carbonation
  5. Swallowing air

Symptoms of Gas Pain:

There are several symptoms to know when it’s gas.

  • Bloating
  • Burping
  • Abdominal pain such as cramps
  • Flatulence (Passing gas through the back)
  • Sharp chest pains that happen suddenly
  • Indigestion

Causes of Heart Attack:

Heart attack is caused by the blockage of blood to the heart and there are different reasons causing it.

  1. Smoking
  2. High-fat diet
  3. Diabetes
  4. High cholesterol
  5. High blood pressure (hypertension)
  6. Obesity

Symptoms of Heart Attack:

  • A feel of heaviness and squeezing pain in the chest
  • Pain in the arms and the left shoulder
  • Shortness of breath
  • Nausea
  • Cold sweat

These symptoms are related to heart attack.

Conclusion

Gas induced pain is typically associated with gastrointestinal issues while a heart attack could signify a severe cardiac condition. Thus, it's crucial to immediately seek a cardiologist if symptoms worsen. Chest discomfort due to gas is usually acute and transient, often following a heavy meal, whereas a heart attack represents a chronic cardiovascular ailment with additional symptoms of coronary artery disease. Given that both conditions involve chest pain, it's imperative not to overlook appropriate medical care.

7 Important Tips to Remember Post your Open Heart Surgery

Heart surgeries are performed to treat heart problems, and “open heart surgery” is one of the techniques through which surgeons can reach the heart. This is one of the reliable ways, where surgeons cut through the sternum (aka breastbone) to get easy access to the heart and is recommended only if the patient is strong enough to brace it.

A patient may require surgery if diagnosed with any one of the following conditions: Congenital heart defects, heart failure, or coronary artery disease etc., It is also common for patients to experience insomnia, depression, muscle pain, and minor swelling near the bruising site. Depending on the intensity and rate of recovery, discharge will proceed, but with loads of directives and advice for care and recovery.

In this article, we are providing you with an insight into what steps and measures are to be followed, post – open heart surgery for a better recovery.

1) Care of incisions

  • Even after 7-10 days, post-surgery, there may be numbness, swelling, redness, and itching in the incision area, which will stop with time. The incision area may become too sore when sleeping in one position for too long and when exposed to weather changes.
  • It’s recommended not to rub the incision, wash with mild soap and pat dry. If the incisions are puffy, reddish, and oozing out, over time, it’s better to seek medical assistance at the earliest. If needed, for discomfort and soreness, the patient may take analgesics as prescribed by the doctor and use a heating pad with low settings for about 20 minutes (4-5 times/day) as instructed by the doctor.

2) Returning to normalcy

  • Habituating to normalcy, even after returning home might be a time-consuming process as our body system would have been changed owing to the major surgery and medications and less physical activity. The recovery period is mostly a mix of both good and bad days, as the patient may not simply feel like themselves, mixed emotions, anxiety, tiredness, irritability, and depression sometimes, and all of this may last for a few weeks to a month or two.
  • One should not be worried because of their different behavior or the mood swings that they go through, as a tremendous amount of psychological energy will be used up in coping with fears and demands post-surgery. Talking with family and friends can greatly benefit the patient in dealing with the emotional roller-coaster and returning to normality.

3) Rest and Sound Sleep

  • Some patients may experience insomnia (inability to fall asleep), post-operation, which may be due to the following reasons: Stress from personal concern, changes in daily routine, discomfort in healing etc., and the normal sleep cycle may typically set in 2-3 weeks.

Tips to restore the sleep cycle:

  • Avoiding caffeine content foods (chocolates, coffee, and colas) during the evening.
  • Taking pain medications at least 30 minutes before bedtime.
  • Choosing a comfortable bedding, pillows, and sleeping position that will not cause discomfort or pain to the incision area.
  • Talking to close ones regarding anxiety or nervousness and getting the troubles out of your mind.
  • Taking a power nap or breaks between normal activities during the daytime.
  • Keeping yourself relaxed by listening to music or reading a book etc.,

4) Physical Activity

5) Pain and relief

  • Pain medication is usually prescribed by the doctor, and will be continued even during a recovery phase.
  • One can benefit from the medication only when one sticks to a treatment regimen without fail, even when at home.
  • Uneasiness surrounding the incision is common but shouldn’t be hurting it does during the initial few days of surgery. This is expected to fade with time, and if not, it is advised to bring it to the attention of the doctor, at the earliest.

6) Sexual Activity

Many patients present with concern about their sexual life when they undergo such a major surgery. Well, it mostly depends on how far they’ve come in the recovery road, both physically and mentally. As per advice, post-surgery, when the patient is fit enough to take two flights of stairs – without falling short of breath or getting too tired, then they’re given the green signal.

7) Diet

Focusing on eating “healthy foods” is a must, post-operation as this majorly contributes to healing, recovering, and reducing the risk of any other complications. One may also experience changes in taste and smell, owing to the medicines that are being taken. It is also prescribed by the nutrition to consume food in smaller portions, but frequently, and it can contain the following:

  • Meat, egg, tofu, nuts and healthy fats
  • Fish – as they are abundant in omega-3 fats
  • Low-fat dairy products
  • Quinoa, rye, rolled oats and other whole grains
  • Water, tender coconut water. Fresh juices
  • Reducing consumption of sugary and carbonated beverages, salt, and junk.

Follow-up appointments and doctor consults are very important and are not to be missed at any cost. The road to recovery may seem like a long tiring one, but one should also remember that they are not alone in this. Family, friends, and rehabilitation groups are available for constant support for “you”- to lead a fulfilling, healthy, and active life in the coming years!!

The heart is an amazing organ that beats around 10,000 times a day, it’s the core that keeps running in the background and keeps us all going. Sadly, heart diseases have become more prevalent in the past decade. The choices we make in our routine lifestyle have direct ramifications on our health. But it doesn’t necessarily have to stay that way, as fortunately, a number of simple day-to-day modifications can benefit in leading a healthier and quality life. Keep scrolling to know more about a handful of easy-peasy tips, that’ll help keep the ticker ticking for a long.

1) Break up and keep moving!

Yes, you read it right! It’s time to break up with the sedentary lifestyle. Sedentary activities include long hours of sitting in front of a television or computer, reading books for a long time, basically being inactive for a lengthy duration. So, it's recommended to get UP and stretch those legs, take small walks, and incorporate any type of movement along with this schedule.

2) Gym membership – Nah! Active membership – YES!!!

With a lot being said about to sedentary lifestyle, not just movements, but physical activity is an important element that must be followed consistently. Working out for 30 minutes/5days a week is more than sufficient. Activities like cycling, brisk walking, beginner’s cardio can be included.

3) Blood check!

Going for regular blood checks, periodic consults with physicians, and knowing the normal values can be very handy in keeping a good health profile. Taking those necessary steps that will keep blood pressure, sugar, cholesterol in check is of prime importance in keeping your heart healthy.

4) “Bon Appetite”!!! Yes, to those healthy fats!

Foods, in general, have good and bad fat. Usually, the good fat (eg., Omega-3) can be sourced from fish, nuts, veggies, and seeds. These good fats contribute to the support of the heart muscles.

5) Oils

Extra virgin olive oil is best known for keeping the heart in a decent shape! So are the other oils which come with its own set of nutrients. Having said this, oils should be used in portions like in dressing or dips and should not be exceedingly used for deep frying. Reuse of oils has also shown have toxic effects on overall health.

6) Going the cholesterol-friendly way!

Cholesterol intake significantly contributes to matters of heart health. Foods such as fatty meat, full-fat dairy products, and lard are examples, which when consumed may cause cholesterol levels to shoot up! Alternating these with healthier substance can help in keeping the cholesterol levels in the healthier range.

7) Chuck out the junk!

Though it may seem irresistible, it can cause some serious irreversible damage to the heart! It is better to avoid anything that basically comes out of packets – biscuits, chips, etc., as they have high trans fats and preservatives.

8) Salt And Sugar!

Intake of salt and sugar in higher amounts results in hypertension, and weight gain etc., Including salt in moderate quantities and choosing alternative for instead of carbonated and sweet beverages like tender coconut water, fresh juices without sugar, etc., can be good alternatives for a heart-beneficial diet.

9) Portion control and weight gain

Both go hand in hand and contribute equally to the heart’s wellbeing. Taking food in measured portions will let us maintain the BMI. Disorganized dieting leads to gaining weight, which further results in diabetes and other deadly disorders of the body.

10) Smoking is injurious to health!

While smoking can have a detrimental effect on health, it intensifies the occurrence of heart disease by 2-4 times. Substance from cigarette is found to cause blocking in the arteries which eventually leads to heart attack. Ditching smoking does good not only for oneself but also for society.

11) Fun between the sheets!

Top or under or between! Just leaving the fact here that an active sexual life has got more to offer than just intimate pleasure. It aids greatly in relaxing, and lowering blood pressure and risk of heart disease as well.

12) Unwind and Sleep!

From youngsters to elderly, stress has become one of the most used words. Not only does this directly harm the heart, but eventually leads to other behaviors – binge eating, alcohol and rug use, etc., Utilise any opportunity that comes by to get some good rest. Unwind yourself by engaging in activities like yoga, listening to music, knitting, crocheting, etc., all of which will greatly help in relieving us of tension and stress.

13) Consider matters of family history

A family member having a history of heart attack increases one’s chance of getting a heart attack. Prevention is better than cure, and in this case consulting a physician, and taking the right steps can be helpful in keeping a healthy heart.

14) Adherence to medication

If a patient, is diagnosed with high blood pressure or diabetes, etc., it is important for them to adhere to the medications prescribed, diet menu, and practice the physical activity recommended. High BP and diabetes are two common conditions, where mismanagement of either one will directly lead to the occurrence of a heart disease.

15) Consistency, patience, and harmony

Though it may seem difficult to bring alterations in our daily lives, it's even more difficult to practice and follow them “consistently”. The patience factor is foremost the important thing when one wishes to see changes. Harmonize the heart with some good aroma therapy, maybe once in two weeks, and treat it to good soothing music. All of these lend a hand in stifling stress, and keeping the heart happy and healthy!
