Trends in Permanent Pacemaker Implantation in Indian Population: A Single Centre Experience

Abstract

Introduction: More than 20,000 pacemakers are implanted each year in India and the numbers are growing annually. Despite this growing numbers, there is no national registry in India who collects or tracks data of implanted devices. Aim: The present study aimed to provide a small fraction of demographic profile of patients who underwent Permanent Pacemaker (PPM) implantation at our premises, one of the largest tertiary care centres in South-east Asia. Materials and Methods: This was a single centre, retrospective study. Patients who underwent pacemaker implantation between December 1999 and February 2014 were included in this study. The data were extracted from a prospectively maintained database, 1551 patients were included in this study. The data analysis was based on patient’s age, gender, indication of PPM implantation, surgical parameters and modes of pacing and pacing parameters. Data were analysed with SPSS. Results: Of the PPM implantation procedures, 56.8% were performed on males and the mean age of population was 60.1 years. The prime indication for pacemaker implantation was degenerative complete heart block (68.3%) followed by sick sinus syndrome (9.0%). Of the total population, 68.3% patients acquired single chamber PPM and 55.9% patients received VVI pacemakers followed by DDDR pacemakers (20.8%). Conclusion: More number of pacemakers was implanted to male patients than female and there was no major age difference between genders. Degenerative complete heart block was the prime indication for PPM implantation. Single chamber devices were used significantly more than the dual chamber devices.
