What is an Event Monitor?

An event monitor is a portable device that is used to record the heart's electrical activity over a period of time. Unlike a Holter monitor, which records the heart's activity continuously for a period of 24-48 hours, an event monitor is activated only when you experience symptoms, such as a rapid or irregular heartbeat.

There are two types of event monitors: a loop recorder and a symptom monitor. A loop recorder is a device that is implanted under the skin, usually in the chest, and continuously records the heart's activity. The device can store several hours of data and can be activated by pressing a button when you experience symptoms.

A symptom monitor is a device that is worn on a belt or carried in a pocket and is activated by pressing a button when you experience symptoms. The device records the heart's activity for a set period of time and then automatically transmits the data to a healthcare provider for analysis.

Event monitors are used to diagnose and evaluate a variety of heart conditions, including arrhythmias (irregular heartbeats), coronary artery disease, and heart valve problems. They can also be used to monitor the effectiveness of treatment for these conditions.

It is important to follow any instructions provided by your healthcare provider and to inform them of any symptoms you experience while wearing an event monitor.
