A pesar del predominio de la estimulación secuencial bicameral (55%), hasta un 21,8% de los pacientes en ritmo sinusal reciben un marcapasos VVI/R. El bloqueo auriculoventricular es la alteración electrocardiográfica más frecuente. Se utilizan mayoritariamente electrodos bipolares y de fijación activa, y tan solo un 20% son compatibles con resonancia magnética. La media de edad al implante es 77,9 años, la mayoría en varones (58,5%). La tasa de implante de generadores de marcapasos convencionales es de 820 unidades/millón y la de terapia de resincronización cardiaca de baja energía, 26 unidades/millón. Se recibe información de 106 centros implantadores, con un total de 12.672 tarjetas europeas, el 32,1% de la actividad total estimada. Se analiza la información aportada por la Tarjeta Europea del Paciente Portador de Marcapasos y la información remitida por la industria sobre el número total de dispositivos implantados. Se describen e interpretan los datos del Registro Español de Marcapasos referentes a la actividad de estimulación cardiaca llevada a cabo en España en 2017. Age is the main factor that influences pacing mode selection, which could be improved in around 22% of patients. Total use of pacemaker generators remains stable with respect to 2016. Patients older than 80 years benefited less from physiological pacing and resynchronization therapy. Most patients received bicameral sequential pacing although single chamber VVIR pacing was used in up to 21.8% of patients. Atrioventricular block was the most common electrocardiographic disturb. Most electrodes were bipolar, with active fixation and only 20% had magnetic resonance protection. The mean age was 77.9 years, predominantly men (58.5%). A total of 333 leadless pacemakers were implanted. Conventional pacemaker and resynchronization pacemaker rate was 820 units/million and 26 units/million inhabitants respectively. Information was received from 106 hospitals, with a total of 12672 cards, representing the 32.1% of the total pacing activity. 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. This report describes the data reported to the Spanish Pacemaker Registry concerning the activity in cardiac pacing in 2017 in Spain.
