Spanish pacemaker registry. 22nd official report of the Heart Rhythm Association of the Spanish Society of Cardiology (2024).

Introduction: This report presents data on cardiac pacing system implants in Spain during 2024.

Methods: The registry is based on data voluntarily submitted by implanting centers to the Heart Rhythm Association of the Spanish Society of Cardiology via the national online platform, CardioDispositivos. Additional data sources included: a) data provided by device manufacturers and distributors, b) the European pacemaker patient card, and c) local databases submitted by implanting centers.

Results: A total of 128 hospitals submitted data to the registry (16 more than in 2023 and 46 more than in 2022). In total, 26 412 units were reported (an 8.5% increase compared with 2023 and 60.8% compared with 2022), vs 47 162 units reported by Eucomed (European Confederation of Medical Suppliers Associations). Among these, 1715 were cardiac resynchronization pacemakers. Leadless pacemaker use continued to rise (1049 devices), accounting for 2.2% of all pacemakers. The most common indication was atrioventricular block, followed by atrial tachyarrhythmia with slow ventricular response. Devices included in remote monitoring also increased: the most notable growth was observed in high-energy resynchronization devices (87%) and leadless pacemakers (38%). Moderate increases were also noted for conventional cardiac resynchronization pacemakers (59%) and standard pacemakers (39%).

Conclusions: Participation in the pacemaker registry continues to grow, reaching 56% of the number of units reported by manufacturers to Eucomed. Remote monitoring maintains the slow but steady growth trend observed in recent years.
