May support minute-ventilation rate-responsive pacing for exercise tolerance in bradycardia; hypothesis-generating and requires randomized confirmation.
Does a minute ventilation sensing rate responsive pacemaker improve exercise capacity and cardiac output compared to VVI mode in patients with bradycardias?
Minute ventilation sensing rate responsive pacing significantly improves exercise capacity and cardiac output compared to fixed-rate VVI pacing in patients with bradycardia.
