Assessment of Stroke Volume and Cardiac Output in Response to Varying Heart Rates

RecruitingNAAges 18 Years - 70 YearsAllUniversity of Calgary
NCT03446326 on ClinicalTrials.gov ↗
💬

In plain words

What the trial is, and whether it could suit you

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.
