What is a Holter Monitor?
A Holter Monitor is a small, portable device that records your heart’s activity. Doctors use it to track your heartbeat over 24 to 48 hours. Unlike a regular ECG, which checks your heart for a few seconds, a Holter Monitor test gives a longer look at your heart’s rhythm. Because it is worn during daily activities, it helps find heart problems that may not show up during a short doctor visit.
Why is a Holter Monitor Used?
Doctors use a Holter Monitor to check for irregular heartbeats, also called arrhythmias. Sometimes, people have symptoms like dizziness, fainting, or chest pain. However, these symptoms may not happen during a regular heart test. Therefore, a Holter Monitor helps catch these issues as you go about your day. It can also help check if your heart medicine is working or if your pacemaker is doing its job.
How Does a Holter Monitor Work?
The Holter Monitor records your heart’s electrical signals. First, a nurse or technician places small sticky patches, called electrodes, on your chest. Then, wires connect these patches to the monitor. You wear the device on a belt or shoulder strap. As you move, the monitor keeps track of your heartbeats. After the test, your doctor reviews the data to look for any problems.
