Spanish Pacemaker Registry. 15th Official Report of the Spanish Society of Cardiology Working Group on Cardiac Pacing (2017)

Abstract Introduction and objectives This report describes the data reported to the Spanish Pacemaker Registry concerning the activity in cardiac pacing in 2017 in Spain. Methods The analysis is based on the data obtained from the European Pacemaker Identification Card and the information reported by supplier companies related to global number of implanted pacemakers. Results Information was received from 106 hospitals, with a total of 12672 cards, representing the 32.1% of the total pacing activity. Conventional pacemaker and resynchronization pacemaker rate was 820 units/million and 26 units/million inhabitants respectively. A total of 333 leadless pacemakers were implanted. The mean age was 77.9 years, predominantly men (58.5%). Most electrodes were bipolar, with active fixation and only 20% had magnetic resonance protection. Atrioventricular block was the most common electrocardiographic disturb. Most patients received bicameral sequential pacing although single chamber VVIR pacing was used in up to 21.8% of patients. Patients older than 80 years benefited less from physiological pacing and resynchronization therapy. Conclusions Total use of pacemaker generators remains stable with respect to 2016. Age is the main factor that influences pacing mode selection, which could be improved in around 22% of patients. Leadless pacing continues to rise.
