Background: Even before it is clinically diagnosed, atrial fibrillation (AF) can cause a stroke. This study validates self-pulse assessment and clinical scoring (MENARI Plus) based on android apps.

Objective: The aim of this study was to examine the validity of AF screening using MENARI Plus compared with an ECG recording.

Methods: We collected a total of 1385 subjects from high-risk population according to CHA2DS2-VASc score ≥2, attending 8 primary care centers (PCCs) in Malang between July 2021 and December 2021. Every participant underwent self-pulse assessment, and then was evaluated for MENARI Plus Score on android Apps. These cases had been classified as low or high probability for AF (cut-off score 7). After that, electrocardiography examinations were performed and classified with AF and Sinus Rhythm group.

Results: In this study, the mean age of these patients was 61.5 ± 6.9 years old. We found that 156/1385 (11%) patients had AF. There were 68/156 (43.5%) new cases of AF. The sensitivity for self-pulse palpation was 73.1% (95% CI: 68%-76%) and specificity was 68.3% (95% CI: 65%-72%). MENARI Plus had an area under the receiver operating curve (AUC) of 0.86 (95% CI: 0.82-0.89) with sensitivity per measurement occasion was (84%, 95% CI: 82%-88%) and specificity was (87.9%, 95% CI: 82%-90%).

Conclusion: In this study, we found that MENARI Plus has high sensitivity and specificity for AF. It is therefore useful for ruling out AF. It may also be a useful screen that can be applied opportunistically for previously undetected AFs.
