Clinical trial for Pulmonary Artery Hypertension
Official title Right Ventricular Pacing in Pulmonary Arterial Hypertension
ClinicalTrials.gov ID: NCT04194632
What this study is testing
- What it's testing
- This study is testing whether pacing the right ventricle helps it pump blood. It also looks at how this affects the heart's energy use.
- Who it's for
- You may be able to join if you have pulmonary arterial hypertension.
- What's involved
- You would have tests to map your heart's electrical signals. Then, a device would pace your right ventricle to check its effect.
- Time commitment
- The source text does not state the study duration or visit schedule.
