   “A pacemaker, also known as an artificial cardiac pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart. Each pulse causes the targeted chamber(s) to contract and pump blood, thus regulating the function of the electrical conduction system of the heart. The primary purpose of a pacemaker is to maintain an even heart rate, either because the heart's natural cardiac pacemaker provides an inadequate or irregular heartbeat, or because there is a block in the heart's electrical conduction system. Modern pacemakers are externally programmable and allow a cardiologist to select the optimal pacing modes for individual patients. Most pacemakers are on demand, in which the stimulation of the heart is based on the dynamic demand of the circulatory system. Others send out a fixed rate of impulses. A specific type of pacemaker, called an implantable cardioverter-defibrillator, combines pacemaker and defibrillator functions in a single implantable device.”

   Volume-outcome analysis of in-hospital complications after cardiac implantable electronic device implantation: a 250 000-case study‡.

   “All peri- and post-operative complications documented in mandatory quality assurance were included. A possible association between implantation volume and quality was assessed using a flexible generalized additive mixed model. Out of 249 118 cases, the overall complication rate was 2.4%, with lead-related issues being the most common (1.5%). Forest plot analysis identified American Society of Anaesthesiologists Class 4-5, New York Heart Association Class IV, subclavian vein access, and dual-chamber pacemaker systems as the strongest predictors of complications. Volume-outcome analysis revealed a significant association between implantation volume and complications, particularly among pacemaker patients [P ConclusionThis study demonstrates a statistically significant association between implantation volume and complication rates across all CIED procedures, with the effect being particularly pronounced among pacemaker patients.”

   Expert Consensus Statement: Committee on Implantable Devices and Committee on Social Issues, Japanese Heart Rhythm Society (JHRS) Statement on Remote Monitoring of Cardiac Implantable Electronic Devices.

   Journal of arrhythmia (Watanabe et al.)Published Sep 1, 2026Checked Oct 11, 2026

   “Remote monitoring (RM) has been established as a standard tool for the management of patients with cardiac implantable electronic devices (CIEDs), offering advantages such as early event detection, fewer routine outpatient visits, and reduced mortality. As RM becomes more common, its appropriate implementation and the need for safe, efficient management have become increasingly important. This statement of the Japanese Heart Rhythm Society (JHRS) provides comprehensive guidance for medical professionals and device manufacturers involved in RM. Specifically, it outlines recommendations on personnel placement, workflow optimization, patient and caregiver education, alert notification settings, physiological parameter monitoring, and insurance claims. It also addresses the responsibilities of device manufacturers, the use of third-party resources, and strategies for reducing workload based on alert notifications. Recommendation classes and evidence levels were determined by the consensus of the writing team, and the proposed recommendations were reviewed and peer-reviewed by the JHRS' Committee on Implantable Devices.”

   Feasibility and Safety of Medium-Term Remote-Only Monitoring in a Large Cohort of Biotronik Pacemaker Patients.

   “Data on the number and causes of additional in-office device interrogations, actions due to the transmissions, hospitalizations and performance of RM were collected from a large cohort of PM patients followed by RM-only.ResultsIn total, 606 patients (302 females) with a mean age of 78 ± 12 years were included in the analysis. During the mean follow-up of 2.8 years, 445 additional in-office device interrogations were made in 287 patients (0.3 interrogations/year), and in 110 (25%) of these cases, changes to device programming were made. In a subgroup analysis of 100 patients with at least one year of prior appointment-based device monitoring, the need for in-office visits was 6.9 times higher per follow-up year than in RM (IRR = 6.9, 95% CI 4.9-9.9; p ConclusionOur real-world data indicate that RM-only may be a viable option for long-term follow-up of PM patients. Portions of this manuscript contain text overlap with our previously published work because they describe the same methodology and standard clinical procedures. All overlapping material has been appropriately cited, and no previously published data, results, or conclusions have been duplicated without attribution.”

   Pacing cessation just before generator replacement - A life-threatening consequence of pacemaker battery depletion: A case report.

   Journal of cardiology cases (Mitsumizo et al.)Published May 7, 2026Checked Oct 11, 2026

   “This lack of surveillance resulted in a critical reduction of the pacing rate to 14 ppm, culminating in the complete cessation of pacing immediately before generator replacement. Despite the Abbott device's specified End-of-Life (EOL) safety mechanism, pacing function failed entirely-a rare but life-threatening complication. Uniquely, this case provides serial electrocardiographic documentation capturing the full progression of severe battery depletion. These findings underscore that continuous follow-up and remote monitoring, as emphasized in recent guidelines, are pivotal for preventing such critical outcomes.Learning objectiveThis case highlights the potential for profound pacemaker rate reduction and complete pacing cessation beyond manufacturer-defined End-of-Life settings in the setting of extreme battery depletion. It emphasizes the importance of regular device follow-up, timely generator replacement, and the use of remote monitoring to detect critical battery status changes and prevent life-threatening complications during pacemaker management.”
