“…Only patients with an atrial lead and CARM were selected for analysis of long‐term recurrence rate after the AF ablation. Automated mode switch (AMS) detection algorithms of different device generations and different device manufacturers generally have a high appropriate AF detection and have been previously described and the AF burden was defined as the cumulative duration of AMS episodes relative to the total atrial rhythm‐monitoring time.…”

“…Automated mode switch (AMS) detection algorithms of different device generations and different device manufacturers generally have a high appropriate AF detection and have been previously described. 11,12 An AMS episode lasting longer than 30 seconds was considered AF according to the current expert consensus on AF ablation 13 and the AF burden was defined as the cumulative duration of AMS episodes relative to the total atrial rhythm-monitoring time. We considered freedom of AF recurrences and freedom of atrial tachycardia (AT) when no AMS episodes lasting longer than 30 seconds were stored on the device, and the AF burden was 0%.…”

Introduction Long‐term efficacy and safety are uncertain in patients with cardiac implantable electronic devices (CIED) and transvenous leads (TVL) undergoing radiofrequency catheter ablation of atrial fibrillation (AF). Thus, we assessed the outcome of AF ablation in those patients during long‐term follow‐up using continuous atrial rhythm monitoring (CARM). Methods and Results A total of 190 patients (71.3 ± 10.7 years; 108 (56.8% men) were included in this study. At index procedure 81 (42.6%) patients presented with paroxysmal AF and 109 (57.4%) with persistent AF. The ablation strategy included pulmonary vein isolation in all patients and biatrial ablation of complex fractionated electrograms with additional ablation lines, if appropriate. AF recurrences were assessed by CARM‐ and CIED‐related complications by device follow‐up. After a mean follow‐up of 55.4 ± 38.1 months, freedom of AF was found in 86 (61.4%) and clinical success defined as an AF burden less than or equal to 1% in 101 (72.1%) patients. Freedom of AF was reported in 74.6% and 51.9% (P = 0.006) and clinical success in 89.8% and 59.3% (P < 0.001) of patients with paroxysmal and persistent AF, respectively. In 3 of 408 (0.7%) ablation procedures, a TVL malfunction occurred within 90 days after catheter ablation. During long‐term follow‐up 9 (4.7%) patients showed lead dislodgement, 2 (1.1%) lead fracture, and 2 (1.1%) lead insulation defect not related to the ablation procedure. Conclusion Our findings using CARM demonstrate long‐term efficacy and safety of radiofrequency catheter ablation of AF in patients with CIED and TVL.

“…Most dualchamber pacemakers employ an automatic mode switch (AMS) algorithm to detect atrial tachyarrhythmias, which was designed to prevent its tracking through to the ventricles and thereby maintain atrioventricular synchrony. By doing so, it also triggers an electrogram (EGM) storage of an AHRE [10]. AMS proves a reliable marker for detection of atrial tachyarrhythmias with a reported sensitivity and specificity of 98.1% and 100%, respectively [11].…”

Aims Undiagnosed atrial fibrillation (AF) accounts for 6% of all strokes, therefore early detection and treatment of the arrhythmia are paramount. Previous research has illustrated that the Microlife WatchBPO3 AFIB, an automated blood pressure (BP) monitor with an inbuilt AF algorithm, accurately detects permanent AF. Currently, limited data exist on whether the modified BP monitor is able to detect paroxysmal AF (PAF). Therefore, this study aims to assess the accuracy of the Microlife WatchBPO3 AFIB monitor to detect PAF against a pacemaker reference standard over a 24-h period. Methods and results Forty-eight patients with a pacemaker implanted for sick sinus syndrome and previously documented fast AF participated. Sensitivity of the atrial pacemaker lead was set to allow detection of signals of ≥ 0.5 mV. Patients engaged in their normal daily routine whilst wearing the modified BP monitor. The modified BP monitor demonstrated an overall sensitivity of 76.0% and specificity of 80.8% for detecting PAF. This sensitivity and specificity increased to 100% and 83.1%, respectively, for patients that achieved more than 80% successful BP readings. Compared to day-time readings, night-time readings also demonstrated a lower proportion of movement artefact (14.4% vs. 3.4%), and therefore, a higher sensitivity and specificity of 100% and 84.9%, respectively, for detecting PAF. Conclusion The Microlife WatchBPO3 AFIB device has an acceptable diagnostic accuracy to detect PAF; however, movement artefact affects the accuracy of the readings. This modified BP monitor may potentially be useful as a screening tool for AF in patients at high risk of developing stroke.
