What is Holter monitoring?

Also known as: ambulatory electrocardiogram (ECG).

Holter monitoring is a test that monitors and records your heartbeat for 24 to 48 hours. It’s typically used to gain more information about an abnormal heart rhythm and determine how long and how frequently the episodes last.
