Brief summary
Background: Ischemic stroke is a leading cause of mortality and disability globally. Atrial fibrillation (AF) is a major cause of stroke. Because AF-related strokes can largely be prevented by oral anticoagulation, an active search for underlying AF is essential in patients with ischemic stroke. In recent years, there has been a surge in the number of health and medical apps for smartphones. Various smartphone apps for heart rhythm monitoring are now available. FibriCheck is one of those smartphone apps that can be used for heart rhythm monitoring and AF detection. It is the first medical smartphone app approved by the United States Food and Drug Administration for heart rhythm disorders. FibriCheck has been shown to have good accuracy in detecting AF. FibriCheck use the phone’s flashlight and built-in camera to register heart rhythm via photoplethysmography technology. To the best of our knowledge, there is no published study on the use of FibriCheck for AF detection after ischemic stroke or transient ischemic attack. Hypothesis: The FibriCheck app could be a convenient and effective rhythm monitoring strategy for the detection of AF in patients with recent ischemic stroke or transient ischemic attack. Aims: • To assess the ease of use of FibriCheck for rhythm monitoring strategy in patients with acute stroke • To evaluate the compliance to FibriCheck monitoring schedule in patients with acute stroke • To determine the AF detection yield of FibriCheck in patients with acute stroke • To compare the accuracy of FibriCheck for AF detection to other rhythm monitoring strategies Procedure: Participants will be recruited in the wards and clinics of the Neurology Department of the Royal Adelaide and Calvary Hospital. 196 patients will be recruited into this observational study. All participants will be asked to take at least 3 measurements daily for 3 months. The FibriCheck app will be provided to the participants free of charge for the duration of the study. All participants will also received a standard of care heart rhythm monitoring using Holter monitor/HeartBug.
Interventions
FibriCheck is a smartphone app that can be used for heart rhythm monitoring and atrial fibrillation (AF) detection. The FibriCheck app will be installed on the smartphone of each consenting participant and detailed instructions will be given on how to use the app. The FibriCheck app will be installed at time of hospital discharge or at a post-discharge clinic visit.

FibriCheck is a smartphone app that can be used for heart rhythm monitoring and atrial fibrillation (AF) detection. The FibriCheck app will be installed on the smartphone of each consenting participant and detailed instructions will be given on how to use the app. The FibriCheck app will be installed at time of hospital discharge or at a post-discharge clinic visit. The FibriCheck app uses the smartphone’s built-in camera to measure the heart rate. The participants will be instructed to be in the seated position with the arms resting on a table, holding their smartphone with the right hand, to not speak or move during the measurement to minimize motion artifacts. For the measurement, they should cover the flashlight and the rear camera with their left index finger, and wait for 60 seconds. The 60-second measurement time for the acquisition of the photoplethysmography (PPG) signal is visualized by a countdown clock on the smartphone screen. After completing the FibriCheck measurement, a context screen will appear where more information can be added to the measurement. Participants will be asked to indicate what they were doing immediately before taking the measurement (sleeping, sitting, standing, walking, exercising, others) and whether they were experiencing any symptoms (palpitations, chest pain, shortness of breath, light-headedness, confusion, fatigue, no symptoms). Participants will be asked to take at least 3 measurements daily for 3 months. Adherence to FibriCheck measurements will be assessed using the app analytics by comparing the number of times measurements were taken to the expected number of measurements (3 measurements daily for 3 months)
