Hartikainen S, et al. - Whether a chest strap (Suunto Movesense) can effectively detect atrial fibrillation (AF) both by cardiologists and automated algorithms was evaluated in this study with 220 patients (107 AF and 111 sinus rhythm SR with 2 inconclusive rhythms). Two cardiologists and two different algorithms were used to analyze a single channel electrocardiogram (ECG) from a chest strap of the participants. For rhythm analysis, a 3-lead Holter was used as the gold standard ECG. The chest strap ECG vs the Holter ECG offered a superior quality, as assessed by both cardiologists. The sensitivity and specificity with two AF detection algorithms from chest strap were 95.3%/96.3% and 95.5/98.2%, and those from Holter were 93.5%/97.2 % and 98.2%/95.5%, respectively. The automated algorithm-based AF detection was accurate. Overall, AF detection by a cardiologist and by automated algorithms was possible with the ECGs from both methods.
