Holter Monitor

A Holter monitor is a small portable electrocardiograph that records your heart's electrical activity during your normal daily routine. By monitoring your heart's performance over a 24-hour period, a Holter monitor can reveal arrhythmias (irregular heart beats) and other heart problems that arise only in certain situations such as emotional stress, sex, eating, or sleeping. You will be asked to keep a detailed journal of your activities during the test to help your cardiologist interpret the results.
