An electrocardiogram is used to examine and monitor the heart. The heart beats are triggered by an electrical impulse which is usually generated from special cells in the upper right chamber of the heart. An electrocardiogram may be used by the doctor to check patterns among these heartbeats and rhythm to diagnose various heart conditions.
An electrocardiogram is a painless method to diagnose many common types of heart problems. It may be used the doctor to detect:
No special preparations are needed for before an electrocardiogram. But, you must avoid drinking cold water or exercising immediately before an electrocardiogram. Cold water can produce misleading results in one of the electrical patterns during the test. Physical activity like climbing stairs, may increase the heart rate.
An electrocardiogram is also called an EKG or ECG. At times the test is called a 12-lead EKG because the heart’s electrical activity most often is recorded from 12 different places on the body at the same time.
