Spanish Pacemaker Registry. Seventh official report of the Spanish Society of Cardiology Working Group on Cardiac Pacing (2009).

INTRODUCTION AND OBJECTIVES: This article describes the finding of an analysis of all pacemaker implants reported to the Spanish Pacemaker Registry in 2009. Particular attention is paid to patients' demographic characteristics and to the pacing modes selected for various electrocardiographic indications. METHODS: The information provided by the European Pacemaker Identification Card was analyzed using a specially developed computer program. RESULTS: Data were received from 106 centers, covering a total of 11,939 cards and corresponding to 35% of all pacemakers implanted. The average age of patients receiving pacemakers was 76.6 years. Overall, 58.4% of pacemakers were implanted in men. The largest number of electrocardiographic indications for a pacemaker was for third-degree atrioventricular block, which comprised 56% of all atrioventricular blocks. The VVIR pacing mode was used for 24.0% of patients with sick sinus syndrome and 23.5% with atrioventricular block. Over 50% of leads employed an active fixation system, and 65% were placed in the atrium. CONCLUSIONS: The trend of increasing pacemaker use continued in 2009, reaching 729 units per million population. Pacemaker implantation was more frequent in males, who received them at a slightly younger age than women. Age was a more significant determinant of inappropriate pacing mode selection than electrocardiographic abnormalities. Active fixation of pacemaker leads was used in more than 50% of cases.

Registro Español de Marcapasos. VII Informe Oficial de la Sección de Estimulación Cardiaca de la Sociedad Española de Cardiología (2009) / Spanish Pacemaker Registry. Seventh Official Report of the Spanish Society of Cardiology Working Group on Cardiac Pacing (2009)

Introducción y objetivos. Se describe el análisis de los implantes de marcapasos remitidos al Registro Español de Marcapasos de 2009, con especial referencia a la distribución poblacional y la selección de los modos de estimulación en las diversas indicaciones electrocardiográficas. Métodos. Procesamiento de la información aportada por la Tarjeta Europea del Paciente Portador de Marcapasos en sus diversos campos empleando una aplicación informática específica. Resultados. Se recibió información de 106 centros, con un total de 11.939 tarjetas, el 35% de todos los marcapasos implantados. La media de edad del paciente que recibió el implante era 76,6 años. El 58,4% de los implantes se hicieron en varones. El mayor número de las indicaciones electrocardiográficas de los implantes fueron los bloqueos auriculoventriculares de tercer grado; los bloqueos auriculoventriculares fueron el 56%. Se estimuló en modo VVI/R al 24% de los pacientes con enfermedad del nódulo sinusal y el 23,5% de aquellos con bloqueos auriculoventriculares. Los cables utilizados fueron bipolares y más del 50% con sistema de fijación activa, el 65% en la posición auricular. Conclusiones. En 2009 persiste la tendencia al aumento del consumo de generadores de marcapasos (729/millón de habitantes), con mayor incidencia en los varones y a una edad ligeramente inferior que en las mujeres. El factor edad es más determinante que la alteración electrocardiográfica en la inadecuada selección del modo de estimulación. La elección de fijación activa de los cables supera el 50% (AU)
