Spanish pacemaker registry. 21st official report of Heart Rhythm Association of the Spanish Society of Cardiology (2023)

Introduction: Data on implants of cardiac pacing systems in Spain in 2023 are presented.

Methods: The registry is based on the information provided by centers to the recording platform of the Heart Rhythm Association after device implantations, through Cardiodispositivos, the online platform of the National Registry. Other information sources include: a) data transfers from the manufacturing and marketing industry; b) the European pacemaker patient card; and c) local databases submitted by the implanting centers.

Results: In 2023, 112 hospitals participated in the registry (30 more than in 2022). A total of 24 343 device implantations were reported (48.1% more than in 2022) compared with 45 120 reported by Eucomed (European Confederation of Medical Suppliers Associations). Of these, 1646 were cardiac resynchronization therapy pacemakers. The devices showing the largest increases were leadless pacemakers, with 963 devices implanted, representing an 18.1% increase over 2022. The most frequent indication was atrioventricular block followed, for the first time, by atrial tachyarrhythmia with slow ventricular response. The number of devices included in remote monitoring also increased (cardiac resynchronization therapy defibrillators, 71%; cardiac resynchronization therapy pacemakers, 63%; and conventional pacemakers, 28%), although more moderately.

Conclusions: In 2023, there was an increase in the number of institutions participating in the registry. The reporting of device implantations rose by 48.1%, and the implantation of leadless pacemakers grew by 18.1%. Remote monitoring also experienced modest growth compared with previous years.
