Assessment of Stroke Volume and Cardiac Output in Response to Varying Heart Rates
Assessment of Stroke Volume and Cardiac Output in Response to Varying Heart Rates and Body Position - a Pacemaker Based Study
Source: ClinicalTrials.gov · Last updated 5 May 2026
Brief summary (registry, in English)
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.
