Mode Selection Trial in Sinus Node Dysfunction (MOST)

This study has been completed.

Sponsored by:	National Heart, Lung, and Blood Institute (NHLBI)
Information provided by:	National Heart, Lung, and Blood Institute (NHLBI)
ClinicalTrials.gov Identifier:	NCT00000561

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.
