Arrhythmia symptoms can be erratic and fleeting. Often unusual cardiac episodes such as dizziness, shortness of breath, rapid heartbeat or irregular heartbeat happens much too quickly and unpredictably to get to your physician in time for an accurate diagnosis. With that in mind, a transtelephonic monitor, or event recorder, may be used to capture valuable information about an episode for later evaluation by your physician.

When symptoms occur, the small, transient event monitor may be attached with bracelets, finger clips or patches under the arms for the purpose of capturing electrocardiogram (ECG) information during the event.
