Experience Of Permanent Pacemaker Implantation At NICVD

Abstract

Our study group com pared 252 new patients who had permanent pacemakers im- planted in the year 1994. Commonest presenting symptom was syncope found in 34.1 % of patients, followed by vertigo in 30.1 %. The most common ECG findings were com- plete heart block with atrioventricular asynchrony, seen in 71.4% followed by Mobitz Type II block in 10.3% and sick sinus syndrome in 7.9%. Mostly VVI type ofPPMs were implanted and other more sophisticated type were used rarely. Aim of Study: In this retrospective study we focused on the com- mon presenting features and ECG findings of patients who required permanent pacemakers. The ages of pa- tients, site of implantation and types ofPPMs used and complications of the procedure were also reviewed. Results: Of the 252 patients 140 (55.55%) were males and 112( 44.45%) were females, with ages varying from 10 yrs. to 94 yrs. The bulk of patients were in 50-70 years age group, 86(34.1 %) of the patients presented with syncope, 76 (30.1 %) with vertigo and 34 (13.4%) with chest pain. Discussion: Each year in our institute we implant between 250-300 new permancent pacemakers besides this patients are admitted for lead repositioning and for change of pulse generator. Conclusion: It is evident that this is an extremely safe procedure in experienced hands and the incidence of serious complications is very low.
