Effect of atrioventricular synchronous pacing on cardiac output determined by CO2 rebreathing at constant submaximal exercise.
This study compared cardiac output assessed by a noninvasive CO2 rebreathing method at identical submaximal exercise and heart rate response in patients undergoing DDD or VVI pacing. Our results did not show any hemodynamic superiority of AV synchronous pacing.
