Using Smart Phone Technology in Detecting the Presence of Atrial Fibrillation

Assessing the Accuracy of an Atrial Fibrillation Detection Algorithm Using Novel Smart Phone Technology in Detecting the Presence of Atrial Fibrillation. iRead Study

The purpose of this study is to examine whether patients can use the AliveCor case to record their heart rhythm and to assess the accuracy of the software in detecting AF vs sinus rhythm

AliveCor is a new monitoring technology used with a smart phone which allows patients to record their rhythm. The study will compare AliveCor recordings and automated interpretation of the rhythm with the interpretation by an Electrophysiologist.

4. Already has iPhone 4, 4S or 5 with data plan that accommodates the AliveCor case
5. Willing to use the Alive Cor case
6. Written informed consent

Exclusion Criteria:
