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.
