Introduction
An electrocardiogram (ECG or EKG) is useful for identifying if the heart is beating normally. It may be used for people with chest pain, heart palpitations, or suspected heart disease. An ECG measures the electrical activity of the heart. It provides information about the size and position of the heart chambers, heart damage, and the effect of a pacemaker or heart regulating medication.
Test Procedure
Prior to your ECG procedure a technician will apply several discs to your skin. The discs are attached to electrodes that transmit information to a recording machine.
During the test, you will be asked to remain motionless or hold your breath at times. An ECG is a painless procedure. The recording machine will print your results. Your doctor will review your results with you.
