Electrophysiologist Salary: What Does it Mean? An Electrocardiologist’s Job Description?

What Is an Electrocardiologist?

Electrocardiologists are medical professionals who specialize in diagnosing and treating heart disease. They use various types of tests to diagnose patients with heart problems such as atrial fibrillation (AF), ventricular tachyarrhythmias (VT) or atrioventricular conduction block (AVCB).

The job description of an electrocardiologist includes:

Understanding the anatomy and physiology of the heart;

Determining whether there is abnormal electrical activity in the heart; and,

Predicting which treatment will improve patient’s condition.

A physician may perform many different types of procedures to treat patients’ diseases. For example, a cardiologist may perform angioplasty to open up blood vessels in the body, while an endocrinologist may prescribe medications to treat patients’ conditions.

An electrocardiologist’s specialty involves using various tools and techniques to diagnose and treat heart disease. Some of these include:

Electrocardiography (ECG);

Echocardiogram; and,

Magnetic Resonance Imaging (MRI).

After performing the initial examination, the electrocardiologist may refer the patient to a cardiac surgeon or cardiothoracic surgeon for further treatment.

The average salary for an electrocardiologist is around $354,720 per year, while the lowest 10 percent of workers earn about $100,880 per year, and the best paid 10 percent earn over $482,420 per year. 1

ECG is a device that records the electrical activity of the heart. In the past, ECG was performed by manually placing metal discs or small metal spools (known as electrodes) on the skin to detect electrical activity.

In recent years, the process has been simplified by using sticky pads that contain an electrolyte gel. These pads are placed on the patient’s chest to pick up electrical activity before being connected to a machine that records the activity. In some cases, a slightly larger pad is placed on the back to record pulse activity.

The ECG machine produces a long paper with squiggly lines. These are known as the electrocardiogram and can be interpreted to determine whether there are any irregularities in the rhythm or structure of the heartbeat.

Common problems that an electrocardiologist diagnoses include:


Long QT syndrome; and,

Angina pectoris.

A common arrhythmia is atrial fibrillation, an irregular heartbeat that can lead to blood clots. It affects around 2.7 million people in the US and can lead to strokes or heart failure if left untreated.2

Long QT syndrome is a condition that can cause an irregular heartbeat that can lead to fainting or sudden death. It can be caused by structural problems with the heart, birth defects or changes in electrolytes.

Angina pectoris is chest pain or discomfort caused by a temporary reduction of oxygen to the heart muscle. It can be triggered by exertion or may occur at rest. 3

After diagnosing patients, electrocardiologists may advise them on lifestyle changes to prevent further problems or complications. These exercises may include quitting smoking, changing diet or lowering blood pressure through taking medication.

An electrocardiologist may also refer patients to other physicians or surgeons for further treatment of complications. These may include:

Antibiotics to treat or prevent infections;

Blood thinners to prevent clots;

Catheter-based procedures to improve blood flow; and,

Percutaneous coronary interventions such as angioplasty or stent placement. 4

A cardiologist is a physician that diagnoses and treats diseases of the heart and blood vessels.

To become a cardiologist, you’ll need to complete a Doctor of Medicine (M.D.) or an equivalent medical degree from a college or university accredited by the Liaison Committee on Medical Education (LCME).

You’ll then be eligible for registration with the State Board of Medicine and can apply for a medical residency in internal medicine followed by four years in cardiology.

A cardiology fellowship can be undergone following the completion of a standard cardiology residency. This involves one year of intensive training in a specialized sub-field of cardiology such as interventional cardiology or electrophysiology. 5 After completing this, you can apply for your state’s medical license.

As an electrocardiologist, you’ll work closely with medical technicians and other physicians to diagnose and treat heart problems, such as abnormal heart rhythms, coronary artery disease and heart failure. 6 You’ll also need to be qualified to perform various tests, such as echocardiograms, Holter monitors and electrophysiology studies.

The average annual salary for an electrocardiologist in the US is around $358,000. 7 This can increase significantly depending on your experience, location and medical specialty. Employers of cardiologists include general medical practices, hospitals and cardiac rehabilitation centers.

There are a number of organizations you can join that offer support and help you stay up to date on advances in electrocardiology and cardiology. These include the Cardiovascular Research Foundation, American College of Cardiology and the Heart Rhythm Society.

Electrocardiograms (ECGs or EKGs) measure the electrical activity of your heart to detect abnormal rhythms, heart attacks and other heart problems. 1 You can request an ECG if you experience symptoms such as chest pain, shortness of breath, fainting and dizziness.

Your electrocardiologist may also recommend an ECG to screen for conditions such as coronary artery disease or atrial fibrillation in patients without any symptoms. 2 These can often be detected before they cause any problems, enabling treatment to begin straight away.

Your electrocardiologist interprets the results of your ECG to help detect any heart conditions and make a diagnosis. If your ECG shows any signs of abnormality, you may be referred to a cardiologist for further tests such as an echocardiogram, cardiac CT scan or cardiac MRI. 3

After identifying a heart condition, your specialist will recommend a treatment plan. They may suggest medication to treat the condition or, in more serious cases, surgery. They might also refer you to a cardiovascular rehabilitation program to help with issues such as exercise and nutrition.

Finding the right doctor is crucial if you want to avoid a heart attack or live a longer, happier life. While there are many different types of cardiologist, some with specific areas of expertise, your best bet is an electrocardiologist.

A disease of the heart and blood vessels, such as coronary artery disease, occurs when the pipes that carry blood to your heart, become clogged and reduce the blood supply to your heart muscle.

The most common symptom of coronary artery disease is chest pain. This is often described as a tight, squeezing pressure, resembling an elephant standing on your chest. It may be triggered by physical activity, such as exercise, or even stress.

Other signs include shortness of breath, feeling sick and light-headedness. Symptoms usually occur when the disease is advanced, but in some cases, you may experience a heart attack without any warning signs.

The most common risk factors for coronary artery disease are smoking, high blood pressure, high cholesterol and being overweight. Other risk factors include diabetes, family history and age. Identifying and removing risk factors as early as possible can help prevent coronary artery disease from occurring.

A cardiologist is a physician who specialises in the diagnosis and treatment of diseases relating to the heart and blood vessels. They are also trained to deal with problems involving the rhythm of the heart. A cardiologist can specialise in one or more areas of cardiovascular medicine, such as pediatric cardiology, electrophysiology, heart failure, cardiac imaging and more.

Your cardiologist can help to prevent heart disease by identifying and addressing any risk factors you may have early on. They can also perform procedures such as angioplasties and pacemaker implantations. If your cardiologist identifies a disease that requires treatment, they will determine the best course of action for you.

A stress test is a procedure that measures the electrical activity and movement of your heart. Cardiologists often use this test to determine your risk of heart disease and to identify any heart conditions you may have, such as blocked arteries.

During a stress test, your cardiologist will have you exercise on a treadmill or pedal a exercise bike while connected to an electrocardiograph (ECG) machine. The ECG machine monitors the electrical activity of your heart.

The exercise starts out at a slow speed and gradually becomes faster, to assess your physical capability for exertion. The test is usually terminated once the ECG shows signs of a dangerous heart rhythm.

Your blood pressure and oxygen uptake are also measured while you exercise. In addition, the cardiologist may request other cardiac imaging tests, such as an echocardiogram or a cardiac computed tomography (CT) scan.

A family history of heart disease is one of the biggest risk factors for developing coronary artery disease, coronary artery disease and heart failure. If any immediate family members have suffered from these diseases, it is advisable to be examined by a cardiologist for early detection of any cardiac issues.

Smoking increases your risk of developing coronary artery disease by fourfold. Each year, approximately seven million people die as a result of smoking-related diseases. When you smoke, the oxygenation of your blood decreases and your heart has to work harder to pump blood through your body.

Over time, this can cause damage to the heart muscle. Quitting can eliminate almost all of the risk factors that come with smoking.

High blood pressure, also known as hypertension, is a major risk factor for heart disease and stroke. When you have high blood pressure, your heart has to work harder to pump blood through your body. This usually results in an enlarged heart, which can lead to heart failure.

High blood pressure is especially dangerous in the long term, as the results of high blood pressure may not be immediately obvious.

Your cardiologist may measure your blood pressure at your annual checkup or they may refer you to a vascular specialist for further assessment and treatment.

Atherosclerosis, also known as hardening of the arteries, is a condition where your arteries become clogged with plaque. This limits the flow of oxygen and nutrients to your heart and brain, which can result in chest pain and shortness of breath. When the blood flow to your heart is compromised, this can cause angina and even a heart attack.

Plaque can also break off from your artery walls and travel through your bloodstream, which can cause a stroke.
