PO-04-155 LONG TERM POST-ABLATION ATRIAL FIBRILLATION MONITORING USING AUTOMATED SINGLE-LEAD ELECTROCARDIOGRAM ANALYSIS

Wearable and handheld consumer electrocardiogram devices may allow for noninvasive, frequent, symptom driven monitoring after atrial fibrillation (AF) ablation. We sought to evaluate the performance of KardiaMobile device AliveCor algorithm in arrythmia recurrence AF Patients a prospective randomized controlled trial adjunctive therapy ablation (NCT04625946) were provided with asked obtain symptomatic or at least weekly recordings before during 1 year follow up. A total 3174 from 50 patients obtained. The automated diagnosis was compared human interpretation which considered gold standard. 772 tracings (24%) demonstrated occurring 38/50 patients. analysis had an overall sensitivity 90.2% specificity 94.3% AF. precision significant inter-patient variation (interquartile range 66.6-100%). In 3/12 without assigned one more tracings. Inaccurate identifications most frequently adjudicated as sinus rhythm (47.7%), premature contractions (23.5%), flutter (8.8%), uninterpretable (6.0%). 58 tachycardia classified ‘tachycardia’ (26%), (21%), ‘unclassified’ (53%) by analysis. use intermittent home facilitate recurrent arrythmias Manual adjudication additional clinical event is likely required especially ectopy postoperative flutter.
