What Is Cardiology?

Is a specialized branch of internal medicine that deals with cardiovascular systems: the heart, arteries and veins.

When Would I See a Cardiologist?

If your general medical doctor feels that you might have a significant heart or related condition, he or she will often call on a cardiologist for help. Symptoms like shortness of breath, chest pains, or dizzy spells often require special testing. Sometimes heart murmurs or ECG changes need the evaluation of a cardiologist. Cardiologists help victims of heart disease return to a full and useful life and also counsel patients about the risks and prevention of heart disease. Most importantly, cardiologists are involved in the treatment of heart attacks, heart failure, and serious heart rhythm disturbances. Their skills and training are required whenever decisions are made about procedures such as cardiac catheterization, balloon angioplasty or heart surgery.



Electrocardiography (ECG or EKG from Greek: kardia, meaning heart) is the process of recording the electrical activity of the heart over a period of time using electrodes placed on a patient's body.

  • Echocardiogram (echo)
  • Cardiac Computed Tomography
  • Exercise Stress Test

Stress Test

A stress test, sometimes called a treadmill test or exercise test, helps your doctor find out how well your heart handles its workload. As your body works harder during the test, it requires more fuel and your heart has to pump more blood. The test can show if there’s a lack of blood supply through the arteries that go to the heart. Taking a stress test also helps your doctor know the kind and level of physical activity that’s right for you.

2D Echo

It is a test in which ultrasound is used to picture out the heart. It is capable of displaying a cross sectional “slice” of the beating heart, including the chambers, valves and the major blood vessels that exit from the left and right part of the heart.

“Doppler” is a special part of the ultrasound exam that assesses blood flow (direction and velocity). Doppler exam shows the flow of blood as it makes its way through and out of the heart. One would hear “swishing” or “whooshing” sounds during this part of the procedure.
