The Relationship between Intracardiac Atrial Sensing Values and Atrial High-rate Episodes in Patients With Permanent Pacemakers Implanted due to Sick Sinus Syndrome

Abstract

Aim: An increase in fibrosis and collagen in the atrium and sinus node tissues constitutes the basic pathophysiology of sick sinus syndrome (SSS). We aimed to investigate the relationship between P-wave sensing values and atrial high rate episodes (AHRE) in patients with dual-chamber (DDDR) pacemakers implanted due to SSS.
