A resting RNA is a type of nuclear medicine test. A tiny amount of radioactive tracer is used during the scan. This test helps evaluate how well the heart pumps and how much blood is pumped with each heartbeat.

A pacemaker is a small electronic device that helps regulate slow electrical problems in the heart. The pacemaker is usually implanted in the chest, below the collarbone. Read on to learn more.

Myocardial perfusion is an imaging test. It's also called a nuclear stress test. It's done to show how well blood flows through the heart muscle. It also shows how well the heart muscle is pumping.

Myocardial perfusion is an imaging test. It's also called a nuclear stress test. It is done to show how well blood flows through the heart muscle. It also shows how well the heart muscle is pumping. For example, after a heart attack, it may be done to find areas of damaged heart muscle. This test may be done during rest and while you exercise.

The Holter monitor is a type of electrocardiogram (ECG) used to record an ECG tracing of the heart continuously for 24 hours or longer.

Heart valve repair or replacement surgery is a treatment choice for valvular heart disease. Learn what to expect before, during, and after this surgery.

A heart transplant is surgery done to remove the diseased heart from a person and replace it with a healthy one from an organ donor.

An exercise echocardiogram is a procedure in which ultrasound, or sound wave technology, is used to asses the heart's response to stress or exercise.

An electrophysiologic study uses small, thin wire electrodes placed directly on the heart to evaluate you for an abnormal heart rhythm.

An electrocardiogram (ECG) is one of the simplest and fastest tests used to evaluate the heart. Electrodes (small, plastic patches that stick to the skin) are placed at certain locations on the chest, arms, and legs. When the electrodes are connected to an ECG machine by lead wires, the electrical activity of the heart is measured, interpreted, and printed out.
