Pregnancy exercise and baby heart health
This trial looks at how a mother's physical activity during pregnancy might affect her newborn's heart function. It is part of a larger study called PregMouv, and researchers want to see if staying active leads to better heart rate variability in babies.
Clermont-FerrandAges 1 day–3 days - NCT07297901Enrolling by invitation
Breathing app study for migraine relief
This trial tests a smartphone-based breathing program to help reduce migraines. It uses heart rate data to guide breathing exercises tailored to you.
Phoenix, ArizonaAges 18 years+ - NCT04777825Recruiting
Biofeedback training to help heart-rate stress signals
This trial studies whether heart-rate variability biofeedback training can reduce distress and symptoms in people whose symptoms seem physical but are linked to psychological factors (somatoform-related issues). It may help you learn to better control stress-related body signals through training sessions.
MontpellierAges 18–75 - NCT06305195Recruiting
Heart rate and risk in metabolic syndrome
This trial looks at how heart rate variability relates to heart disease risk in people with and without diabetes or pre-diabetes. It may help understand which patients need closer monitoring.
AlexandriaAges 18–70 - NCT06739993Recruiting
Can breathing exercises improve blood sugar in prediabetes?
This study tests if a special breathing technique (heart rate variability biofeedback) can help people with prediabetes improve their blood sugar control. You will attend screening visits and practice breathing exercises at home to see if this lowers your risk of developing diabetes.
Mainz, MainzAges 18–65 - NCT06744244Recruiting
Smell test for newborns with birth asphyxia
This study tests whether a simple smell test can help doctors better understand the risk of brain injury in newborns who had oxygen loss at birth. It may help identify babies who need extra monitoring without requiring cooling treatment.
ParmaAges 6 hours–3 days - NCT06813495Recruiting
ACT for injury prevention in nurses and aides
This study tests a program called Acceptance and Commitment Therapy (ACT) to help nurses and nursing aides prevent injuries at work. If you work in a long-term care facility in specific areas of the US or Thailand, you may be able to join.
Bowling Green, OhioAges 18 years+ - NCT07350759Recruiting
Using a wearable to detect heart failure worsening
This study tests if a wearable device can spot early signs of heart failure getting worse. If you already use a heart monitor and have stable readings, you may help show how a non-invasive wearable could alert you sooner.
Tampa, FloridaAges 18 years+ - NCT07389135Recruiting
Heart rate and anxiety after nose surgery study
This study looks at whether your heart rate patterns and anxiety levels before surgery can predict how you will wake up after nose surgery (septorhinoplasty). If you are scheduled for this surgery, they will measure your heart rate and ask you questions about anxiety to see if these can help reduce confusion or agitation when you wake up.
Konya, KaratayAges 18–65 - NCT07518862Recruiting
Using heart rate to guide oxygen therapy settings
This study uses a simple, non-invasive test (heart rate monitoring) to help doctors adjust the flow of oxygen therapy through a nasal cannula. It may help improve how well this breathing support works for you.
Toronto, OntarioAges 18 years+ - NCT06954103Recruiting
Stroke and heart health study for recent stroke patients
This study looks at how a moderate to severe stroke can affect your heart. It aims to understand the link between stroke and heart problems, which may help improve future care.
Wuhan, HubeiAges 18 years+ - NCT04014829Recruiting
Study of pain processing after planned hysterectomy
This trial looks at how the nervous system and fear of pain may affect pain after a planned hysterectomy. If you qualify, you may be asked about pain levels and pain sensitivity to better understand who may have more pain recovery challenges.
SingaporeAges 21–80 - NCT07756723RecruitingPhase 2/Phase 3
Comparing PTSD treatments for veterans with substance use
This study compares two proven treatments for veterans who have both PTSD and substance use problems. It aims to find which treatment works best to help with trauma recovery.

Heart rate measurement on arm vs. chest during nerve stimulation
This study compares two ways of measuring heart rate variability (a sign of how well your nervous system is working) during a gentle nerve stimulation therapy. It looks for healthy volunteers to see if a simple arm measurement works as well as a chest measurement.
Trabzon, OrtahisarAges 18–45 - NCT04959838Recruiting

- Yes. Clin2 currently lists 76 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.
