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

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.
