24 Hour Holter Monitor

A Holter Monitor is a compact medical device that measures your heart’s activity, such as rate and rhythm. Your General Practitioner or Cardiologist may ask you to use one if they need more information about how your heart functions than a routine ECG can give them.


24 hour Holter monitoring is a continuous diagnostic study to record your heart’s rate and rhythm over a 24 hour period. 


A Holter monitor has electrodes and leads exactly like a regular ECG, except it has fewer leads. It can pick up not only your heart’s rate and rhythm but also when you feel chest pains or exhibit symptoms of an irregular heartbeat which is called an arrhythmia.


Holter monitor testing is also sometimes called ambulatory electrocardiography.
