Clinical Trial: Minimizing Ventricular Pacing

Study Status: Recruiting
Recruit Status: Unknown status
Study Type: Interventional

Official Title: Minimizing Right Ventricular Pacing in Dual-chamber Pacemaker Patients With Sinus Node Disease and First Degree Atrioventricular Block.

Brief Summary: The aim of this study is to evaluate the effect of minimizing right ventricular pacing in dual-chamber pacemaker patients with sinus node disease (SND) and first degree atrioventricular block (AVIB)on exercise capacity, quality of life and other heart failure measures.
