This is an important test because your doctor can diagnose what condition you have even if wearing this can be a little inconvenient.

Here are the most common reasons to receive a Holter monitor.

Your doctor will first recommend electrocardiogram if you have signs and symptoms of a heart problem such an unexplained fainting or irregular heartbeat (arrhythmia).

But if the test does not work because you are only hooked up to the machine for a short time, he may suggest the use of Holter monitor for a day or two to check your heartbeat if it suggests occasionally irregular heart rhythm.
