Holter monitors record your heart beat as you go about your daily activities. This monitoring helps the doctors evaluate the functioning of your heart. If your physician has ordered a Holter monitor, you will be coming to the office to receive the monitor and keeping it for 24 hours. Small painless electrodes will be placed on your chest. They connect to the lightweight recording unit, which attaches to a belt or shoulder strap.
The most common type of cardiac event monitor is called a loop monitor. When you feel symptoms, you press a button and the monitor records your heartbeat. Other types of event monitors are worn on your wrist or carried in a purse or pocket. When you feel symptoms, you activate the device by pressing a button or holding the monitor to your chest.
