A Holter monitor is a small, wearable device that keeps track of your heart rhythm. It is usually worn for one to two days. During that time, the device records all of your heartbeats.
A Holter monitor test is usually performed after a traditional test to check your heart rhythm (electrocardiogram) if the electrocardiogram doesn't give your doctor enough information about your heart's condition.
Your doctor uses information captured on the Holter monitor to figure out if you have a heart rhythm problem. If standard Holter monitoring doesn't capture your irregular heartbeat, your doctor may suggest a wireless Holter monitor, which can work for weeks.
While wearing a Holter monitor may be a little inconvenient, it's an important test that may help your doctor diagnose your condition
Cardiac Event Monitor
A cardiac event recorder is a battery-powered portable device that you control to tape-record your heart's electrical activity (ECG) when you have symptoms. There are two types of event recorders: a loop memory monitor and a symptom event monitor.
Mobile Cardiac Outpatient Telemetry
The MCOT system is like Hospital Telemetry outside the hospital, monitoring patients in real-time during normal daily activities, using built-in detection algorithms and cellular technology. It is used when shorter term monitors such as holters fail to diagnose a problem or for longer term monitoring to evaluate arrhythmias even when no symptoms are experienced
