Using heart rate to predict brain injury after cardiac arrest
This study looks at how your heart rate changes (heart rate variability) to predict brain injury after a cardiac arrest. It may help doctors identify brain damage earlier so they can provide better care.
Brest, Brittany RegionAges 18 years+ - NCT07548723Enrolling by invitation
Nerve Stimulation Device Reliability Study
This study tests how reliably a small ear-stimulation device measures heart-rhythm patterns. Researchers want to see if the device gives consistent readings across multiple measurement sessions, which could help doctors monitor heart health in the future.
SinopAges 18–40 - NCT07521956Recruiting
Mindfulness training for recreational runners
This study tests whether a mindfulness program can help recreational runners improve their performance, breathing, and heart rate patterns. If you're a regular runner, this trial explores whether mental training alongside your running could enhance your physical abilities.
Chilliwack, British ColumbiaAges 19 years+ - NCT07504640Recruiting
Spinal manipulation for heart health in children with cerebral palsy

Heart rate changes in people with a specific dizziness condition
This study looks at heart rate differences in people who have brief episodes of spinning dizziness (BPPV) compared to healthy people. It aims to see if the dizziness affects how the heart responds.
Istanbul, KüçükçekmeceAges 18–65 - NCT04829877Recruiting
Study stress changes in women trying to get pregnant
This study follows how emotional distress changes over time in women who are starting infertility treatment and trying to conceive. It may help researchers understand what support might be most helpful during the start of fertility care.
TaipeiAges 20–60 - NCT07455214Recruiting
Heart rate variability and breathing trial success in ventilated patients
This study looks at whether heart rate patterns can help predict if a person on a breathing machine is ready to breathe on their own. It may help doctors decide the best time to try removing the breathing tube.

Common questions
- Are there clinical trials for heart rate variability?
- Yes. Clin2 currently lists 75 recruiting heart rate variability studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a heart rate variability trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a heart rate variability trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
