What Are Holter and Event Monitors?

Holter monitors

A Holter monitor is a small, portable device that records your heart's electrical activity (ECG) for a period of 24 hours or longer. It's used to diagnose and monitor heart conditions, such as:

* Arrhythmias (irregular heartbeats)

* Bradycardia (slow heart rate)

* Tachycardia (fast heart rate)

* Chest pain

* Palpitations (a feeling of your heart racing or skipping beats)

* Syncope (fainting)

Holter monitors are typically worn around your neck or waist. They have electrodes that attach to your chest to record your ECG. The monitor will store your ECG data and transmit it to your doctor for analysis.

Event monitors

An event monitor is a small, portable device that records your heart's electrical activity (ECG) when you experience symptoms, such as:

* Chest pain

* Palpitations

* Syncope

* Lightheadedness

* Dizziness

Event monitors are typically worn for a period of 2 weeks to 1 month. They have a button that you can press to record your ECG when you experience symptoms. The monitor will store your ECG data and transmit it to your doctor for analysis.

Which monitor is right for me?

Your doctor will recommend the type of monitor that's right for you based on your symptoms and medical history.

How to use a Holter or event monitor

Your doctor will give you instructions on how to use your Holter or event monitor. In general, you will need to:

* Wear the monitor for the prescribed amount of time.

* Keep a diary of your symptoms.

* Avoid activities that could interfere with the monitor's recordings, such as showering or swimming.

* Return the monitor to your doctor as directed.

Holter and event monitors are safe and convenient devices that can help diagnose and monitor heart conditions.
