What is Holter monitoring?

A Holter monitor is a small wearable device that tracks and records the electrical rhythms of your heart as you move around doing the normal things you do in daily life, usually over 24 or 48 hours.

It provides information about how the changes in your heart rhythm correspond with your daily activities and sleep patterns and it is used to investigate a range of symptoms such as dizziness or palpitations.

Having a monitor fitted is straightforward. Follow our step-by-step guide to know what to expect.
