An EKG, or "Electrocardiogram", is a very common test that evaluates the electrical system of the heart. It can be used to diagnose heart rhythm problems, heart attacks, or other medical conditions happening currently or which have happened in the past.
No real preparation is required prior to having an EKG; sometimes hair may need to be shaved in the area in which the ten EKG patches are to be placed.
The test takes only a few minutes, patients must hold still at the time the EKG is being recorded, but there is no pain involved. Patients are usually supine, or on the back, while the EKG tracings (generally two) are being printed. The test has no risks, there is no after-procedure care necessary, and the results can be interpreted immediately.
