Person having an ECG
This drawing shows a man having an ECG (also called an electrocardiogram or EKG). He has patches, called "electrodes," stuck onto his chest, arms, and legs. Wires run from the electrodes to the ECG machine. An ECG measures the electrical activity in the heart.

Transthoracic echocardiogram (echo)
This picture shows a person getting an echocardiogram (or "echo"). To do an echo, a doctor or nurse puts some gel on a persons chest. He or she presses a thick wand (called a "transducer") against the chest and moves it around. An echo uses sound waves to create images of the heart that appear on a computer screen. A test called an ECG is done during an echo. For an ECG, patches (called "electrodes") are stuck to a person's chest. Wires run from the patches to a machine that records the electrical activity of the heart.

Cardiac catheterization
For a cardiac catheterization, your doctor will make a very small cut in the top, inner part of your leg, or arm. He or she will put a thin plastic tube, called a "catheter," in a blood vessel below the cut. Then he or she will move the tube through your blood vessels to your heart. When the tube is in place, your doctor can do different tests. Most people have a test called "coronary angiography. " пїЅ For this test, your doctor will inject a dye that creates pictures to show if your heart arteries are clogged.
