A Methodological Open Label Cross-Over Controlled Study To Assess The Effect Of Drugs On Ventricular Repolarization and QT Interval At Fixed Heart Rate Under Autonomic Blockade

This study has been completed.

Sponsored by:	Pfizer
Information provided by:	Pfizer
ClinicalTrials.gov Identifier:	NCT00174512

Purpose

To assess the effects of GTN on QT and QTc in subjects with And without atrial pacing. This will be done with and without autonomic blockade at two different pacing rates. Moxifloxacin effect on QT and QTc will also be assessed in atrially paced patients at two different pacing rates with and without autonomic blockade
