Holter Monitoring (Ambulatory EKG Monitoring)

This is a way to detect suspected arrhythmias (heartbeat rhythm that is irregular, too fast or too slow). It
means wearing a small, portable, battery operated EKG recorder, called a Holter monitor. It records continuous EKG information, for one to five days, on a tape. This recorded data is then analyzed by your doctors.

Event (loop) Monitoring

Like Holter monitoring, event monitoring involves wearing a very small, portable, EKG recorder. But a Holter monitor is worn for a few days at most; an event monitor can be worn for months. And a Holter monitor records EKG signals continuously; an event monitor is activated when you have "an event," that is, you feel the symptoms of your heart problem (an arrhythmia, for example). The recorded data can be sent over the phone to your doctors for analysis. There are several types of event recorders, from wristwatch size devices to those that can be implanted for up to 18 months.

Transtelephonic Monitoring (Event Monitoring or Loop Monitoring)

The technology that enables event monitoring (data recorded by a small, portable EKG is sent by telephone for analysis) can also be used to send data from an implanted pacemaker or ICD (implanted cardioverter defibrillator).
