Holter Monitor

Holter Monitor

Electrical impulses cause the heart to beat 60 to100 times a minute. These impulses come from a natural pacemaker deep inside the heart muscle. Each impulse causes the heart muscle to contract. This action causes the blood to flow through the heart chambers and out to the tissues and organs of your body.

An arrhythmia is a change from the normal speed or pattern of these electrical impulses. This can cause the heart to beat too fast (tachycardia); or, too slow (bradycardia); or in an unsteady pattern (irregular rhythm).

Knowing the type of arrhythmia will help your doctor identify the cause and the best treatment to use. A Holter Monitor is used to identify the arrhythmia. This is a portable device (like a tape recorder) that you wear. It records your heartbeat over time (for example, 24 hours). Any arrhythmia that occurs during the test period will be captured on the recording for your doctor to see.

Call as directed to make an appointment to get your Holter Monitor. The staff there will explain how to use it.
