01 — Overview
About Holter
A Holter monitor records every heartbeat, usually over 24 to 48 hours, while you go about your normal day. It is useful when symptoms are occasional and may not appear during a short ECG.
Comparing the recording with a diary of your symptoms helps your cardiologist see whether palpitations or dizziness are linked to a rhythm problem.
