Holter Monitor

Excerpt

A Holter monitor is an ambulatory electrocardiographic system discovered by Dr Norman J Holter and his team in 1957 (see Image. Holter Monitor). Little did they know that their device would change how we track cardiac rhythms outside the hospital.

Historically electrocardiography began in 1893 with the work of Einthovens string galvanometer. The Holter monitor is a device that works on Galvanometer's principle to record electrocardiographic signals from an individual going about his daily activities, like continuous ambulatory electrocardiography. From 1961, various other modalities and advanced gadgets have been manufactured for this purpose. Since then, it has formed the backbone of rhythm detection and analysis in Cardiac Electrophysiology.
