Assessment of Stroke Volume and Cardiac Output in Response to Varying Heart Rates
Sponsor: University of Calgary
Summary
The investigators will seek to determine the effects of different heart rates on both stroke volume and cardiac output using non-invasive hemodynamic assessments. In order to safely manipulate the HR, the investigators will study patients with permanent pacemakers in whom heart rate manipulation can be done in a safe and non-invasive manner.
