This is a drawing of a normal heart. The heart has 4 chambers: right atrium, left atrium, right ventricle, and left ventricle. Blood flows from the right atrium to the right ventricle through the tricuspid valve. Blood flows from the left atrium to the left ventricle through the mitral valve.

View OriginalPerson 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.

View OriginalTransthoracic 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.

View OriginalCardiac 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. " � For this test, your doctor will inject a dye that creates pictures to show if your heart arteries are clogged.
