An observational study of pattern of bradyarrhythmia and pacing management modality in geriatric population: A single-center 2-year analysis data

Abstract

Background: Incidence of cardiac conduction disorders are escalating in the current era especially due to enhanced life expectancy in the geriatric population and better standards of medical care and coronary revascularization. Aims and Objectives: This study aimed to analyse the demographical aspect and temporal trends of permanent pacemaker (PPM) therapy in patients aged above 60 years of age from an observational 2-year retrospective data from a single-center tertiary care academic hospital. Results: Males consisted of more than two-third of the patients and complete atrioventricular block was the most common conduction pathology. Fascicular and Bundle branch blocks appeared to have a male preponderance, whereas sinus node dysfunction was found to have statistically significant association with the female cohort. Most of the patients were implanted out of admission from cardiac emergency and single chamber ventricle paced and sensed, inhibition response with rate adaptation (VVIR) mode was the predominant modality of pacing management, not found to be influenced by the age or sex of the patients. However, there was a statistical correlation noted of utilization of dual chamber Dual paced and sensed, dual inhibition with rate adaptation (DDDR) mode in patients with sick sinus pathology. Conclusion: Implantation of PPM is on the rise as a modality of bradyarrhythmia treatment in the increasing proportion of geriatric population with advanced life expectancy.
