Spanish Pacemaker Registry. 17th Official Report of the Section on Cardiac Pacing of the Spanish Society of Cardiology (2019)

Introduction and objectives: This report describes Spanish cardiac pacing activity during 2019: quantities and types of devices and demographic and clinical factors. Methods: The analysis is based on data obtained from the European Pacemaker Patient Identification Card, data submitted to the online platform cardiodispositivos.es, and supplier-reported data on the total number of implanted pacemakers. Results: Information was received on 15 833 procedures from 102 implantation centers, representing 39% of the estimated total activity. The implantation rates of conventional and resynchronization pacemakers were 832 and 32 units per million population, respectively. A total of 431 leadless pacemakers were implanted. Most implantations were performed in elderly patients (mean age, 78.7 years). Most electrodes were bipolar and with active fixation and 34.1% were magnetic resonance imaging-compatible. Atrioventricular block was the most common electrocardiographic abnormality. Dual-chamber sequential pacing predominated; nonetheless, up to 20% of patients in sinus rhythm received a single-chamber ventricular pacemaker, mainly those older than 80 years of age and women. Remote monitoring capability was present in 41% of cardiac resynchronization therapy pacemakers and in 14.8% of conventional pacemakers. Conclusions: Consumption of pacing generators increased by 1.6%, mainly due to a 15.1% increase in cardiac resynchronization therapy pacemakers. Sequential pacing predominates; its use is influenced by age and sex. Remote monitoring increased by 20.6% in cardiac resynchronization therapy pacemakers and continues to be scarce in conventional pacemakers. (C) 2020 Sociedad Espanola de Cardiologia.
