Background: Recent enhancements have been introduced to the Abbott Confirm Rx™ insertable cardiac monitor (ICM) arrhythmia detection algorithms (SharpSense™). This study aims to characterize the real-world performance of SharpSense™ algorithms, in the upgraded ICM devices by comparing device detected pause and bradycardia (brady) episodes before and after the SharpSense™ upgrade. Methods: Confirm Rx™ devices with at least 90 days monitoring each before and after SharpSense™ upgrade were included in the study. Brady and pause episodes were extracted from Merlin.net™ patient care network for evaluation and adjudicated by expert adjudicators. Results: A total of 197 devices were included in the analysis. Devices were implanted for syncope (35%), AF management (33%), and other indications, including cryptogenic stroke and palpitations (32%). The SharpSense™ upgrade significantly reduced the total number of detected episodes by 92% (pause: 93%, brady: 87%) and the rate of transmitted episodes by 73.6% from 50.3 to 13.3 (pause: 34.9 to 6.0, brady: 7.8 to 1.5) episodes per patient-week (p < 0.001). SharpSense™ reduced false positive episodes by 82.8% and 91.5% for pause and brady, respectively. The percentage of devices with at least one false positive episode was reduced from 52% to 35% for pause and from 39% for 20% for brady. The number of devices with false positive rate greater than 1 episode per week was reduced from 39% to 20% for pause and from 23% to 8% for brady. Conclusion: SharpSense™ upgrade resulted in substantial reduction of pause and bradycardia episode detections, false positive detections, and frequency of transmitted episodes for clinic review.

Abstract Background: With the increasing number of aged population in China, the mortality and disability caused by atrial fibrillation (AF) and its complications lead to serious social burden and becoming more prominent. Due to the high false-negative rates of AF detected by routine ECG, the results on the recurrent rate and AF burden after cryoballoon ablation (CBA) in real world are inconsistent so far. Since the extension of monitoring time, the increased detection of AF in patients, insertable cardiac monitor (ICM) has its unique merits. Methods: Cryo-ICM AF study is a prospective, multicenter randomized controlled trial with 200 participants with paroxysmal atrial fibrillation from 4 centers. Monitoring AF load after CBA though two monitoring methods— ICM and 24 hours holter during the 1 years follow-up of the two groups. All data will be observed and recorded in baseline, 30th days and 3 th , 6 th , 9 th and 12 th months after CBA, which including incidence rates of postoperative complications and recurrence conditions, cardioelectrical indexes from 24-hours holter in all subjects and ICM in ICM group, UCG parameters about atrium/ventricular size and diastolic/systolic function, and biochemical indicators. Disucssion: This is the first study design to confirm the effectiveness of cryoballoon in real world, monitoring AF load with ICM in patients with paroxysmal AF after CBA.Trial registration: Chinese Clinical Trial Registry, No. ChiCTR1900026364.
