Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Estimate of the accuracy of algorithm based PPG irregular rhythm detection in a study population with a history of paroxysmal or persistent atrial fibrillation (AF) [ Time Frame: At least 60 minutes ]
    Sensitivity estimate for PPG irregular rhythm detection vs. a multi-lead Holter ECG rhythm

  2. PPG- and ECG-based continuous AF-detection algorithms on Study Watch in a free-living (home) setting by comparing the Study Watch data with an FDA-cleared wearable ECG sensor data. [ Time Frame: 14 days ]
    Number of AF events identified from FDA-cleared ECG Device


Secondary Outcome Measures :
  1. Estimate of the accuracy of algorithm based PPG irregular rhythm detection in a study population with a history of paroxysmal or persistent atrial fibrillation (AF) [ Time Frame: At least 60 minutes ]
    Predictive value estimate for PPG irregular rhythm detection vs. a multi-lead Holter ECG rhythm

  2. Spontaneously-reported participant usability feedback for Study Watch and its ECG feature in a free-living (home) setting with the target AF population. [ Time Frame: 14 days ]
    Qualitative listing of participant-reported feedback
