Holter Monitor

Holter Monitors are a small, battery-powered medical device worn around the neck to record your heartbeat. The monitor is usually worn for one to two days and gives the doctor detailed information on a potentially irregular heart rhythm.


Sometimes an electrocardiogram does not detect any abnormalities because the heart is at rest and an EKG only monitors your heart’s rate and rhythm for a short period or time. Your doctor might recommend a Holter Monitor if an electrocardiogram is inconclusive or you require a record of continuous monitoring of about twelve to twenty-four hours.

The device is put in place during an appointment. Make sure to shower beforehand because most monitors need to be kept dry and cannot be removed. You will likely be asked to keep a journal of all activity and how you feel while wearing the monitor.
