Coronary artery bypass surgery creates a path for blood to flow around a blockage and helps prevent a heart attack.

Atherectomy is a procedure that relieves symptoms of coronary artery disease by improving blood flow to your heart.

Angioplasty relieves symptoms of coronary artery disease by improving blood flow to your heart. Read on to learn what to expect before, during, and after the procedure.

An EPS closely monitors your heart rhythm. EPS can help find out exactly what your rhythm problem is and what can be done to control it. A specially trained doctor (electrophysiologist) does the procedure in an EPS lab.

The ECG is a test that records electrical signals from your heart. The pattern of these signals can tell the healthcare provider if your heart is normal, under stress, or having electrical problems, strain, or damage.

A transthoracic echocardiogram (echo) is an imaging test. It helps your doctor assess your heart. Here's how it works.

Angiography is a special type of x-ray that allows your coronary arteries to be viewed and recorded on film. Your doctor can see if the blood vessels to your heart are clogged.
