What is a 24-Hour Holter Monitor?

A 24-hour Holter monitor is a small, wearable device that records your heart's electrical activity (your heartbeat) continuously over a full day and night. It’s like an extended, portable version of an ECG (electrocardiogram). You wear it while you go about your normal daily activities, including sleeping.

The monitor consists of:

• Small sticky patches (electrodes) attached to your chest.

• A lightweight recording device that connects to the electrodes.

Why is a 24-Hour Holter Monitor Important?

Your heart doesn’t always show signs of a problem during a short doctor’s visit or a brief ECG. The Holter monitor helps your doctor:

• Catch irregular heartbeats (arrhythmias): Sometimes, abnormal rhythms come and go. The Holter monitor records your heart 24/7, increasing the chance of detecting these.

• Monitor for symptoms: If you’ve been feeling dizzy, faint, or have unexplained chest discomfort, the device helps correlate your symptoms with your heart’s activity.

• Check your heart’s response: It can show how your heart reacts to normal activities, stress, and rest, giving a more complete picture of your heart’s health.

• Assess treatment or pacemaker function: It ensures any medication or device is working effectively.
