Validation of an iPhone-based Event Recorder for Arrhythmia Detection
Validation of an iPhone-based Event Recorder for Arrhythmia Detection
In this study, we will evaluate the diagnostic yield of the new AliveCor device versus a 14
 day event monitor with the use of both devices simultaneously. We will also examine by means
 of a questionnaire the compliance, ease of use and patient satisfaction for each device.

 Hypothesis:

 1. The AliveCor monitor will be non-inferior to the 14 day event monitor with respect to
 diagnosis of the arrhythmia responsible for a patient's symptoms.

 2. The AliveCor monitor will have better compliance and acceptability compared to the 14
 day event monitor, and thus there will be a greater number of days with recordings from
 the AliveCor monitor.
Inclusion Criteria:

 Patients >18 years of age with symptoms such as palpitations or pre-syncope suggestive of
 arrhythmias (usually occurring less frequently than once a day) with prior non-diagnostic
 ECGs and/or Holter monitoring.

 Patients who own an iPhone 4, 4S or 5 device and demonstrate the capability of recording
 and uploading a test ECG recording at the office visit.

 Exclusion Criteria:

 1. Patients <18 years of age.

 2. Patients with a myocardial infarction (MI) within the last three months, and/or known
 history of sustained VT/VF.

 3. Patients with NYHA class IV heart failure.

 4. Patients with unstable angina.

 5. Patients with syncope as the presenting symptom.

 6. Patients unable to or unwilling to use the device.
