Mode Selection Trial in Sinus Node Dysfunction (MOST) - Full Text View

Purpose

To determine if dual chamber rate-modulated pacing (DDDR) in patients with sick sinus syndrome is superior to single chamber pacing (VVIR) with respect to subsequent frequency of adverse clinical events such as stroke, quality of life and function, and cost effectiveness.
