Design outcomes

Primary

MeasureTime frame
Analysis of the degree of agreement between Apple Watch heart data collected while subjects are at rest or sleeping (pulse rates, irregular heartbeat notifications, and ECG recordings) and 14-day ECG patch data (atrial fibrillation events).

Secondary

MeasureTime frame
- Construction and evaluation of a machine-learning algorithm to identify the optimal timing of pulse/ECG recording for arrhythmia detection. - Evaluation of the relevance of Apple Watch healthcare data and 14-day ECG patch data, profile data, questionnaire data, and information from medical records, including data from transtelephonic monitors.
