The heart on the left is normal. The heart on the right has hypertrophic cardiomyopathy. The condition causes the walls of the lower chambers of the heart (called the ventricles) to thicken.

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 OriginalHolter monitor
People with possible heart problems are sometimes asked to wear a device called a Holter monitor for 1 or 2 days. The device measures the electrical activity in the heart. It helps doctors pinpoint heart rhythm problems. You will have "electrodes " � stuck to your chest that are connected to wires leading to the monitor. These electrodes tell the monitor how often your heart beats and if it has a normal rhythm. While you have a Holter monitor on, you should do your normal activities but keep the electrodes, wires and device dry. Some people have an abnormal heart rhythm only during certain activities or certain times of the day.
