Heart rate variability and delirium after major abdominal surgery in older adults
This study looks at whether heart rate variability (a measure of your heart's ability to adapt to stress) can help predict delirium (confusion or disorientation) after major abdominal surgery in older adults. You may qualify if you are 65-85 years old, having major abdominal surgery, and do not have serious heart, nervous system, or memory problems.
Nanjing, JiangsuAges 65–85 - NCT07709364Recruiting
Heart rate feedback to help nurses make better decisions

Cambridge, CambridgeshireAges 21 years+ - 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 - 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.

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+ - 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 - NCT07386951Recruiting
Heart rate biofeedback for security force personnel
This trial tests whether a biofeedback technique that improves heart rate control can help military personnel manage stress and perform better in their duties. You would learn a simple relaxation method while on active duty.
SetúbalAges 18–55 - NCT07376616Recruiting
Heart health study during pregnancy and after birth
This study looks at how the heart adapts during pregnancy and the months after giving birth. It uses simple tests to measure heart rate and blood flow, which may help doctors better understand normal changes and identify risks early.
Vigo, PontevedraAges 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+ - 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+ - NCT07264400Recruiting
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 - NCT06929208Recruiting
Music and heart rate during procedures
This trial studies how listening to music affects your heart rate and stress response during a procedure like surgery or a pain treatment. It may help you relax and feel more comfortable.
SingaporeAges 21–90 - 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 - NCT04367987Recruiting
Heart Rate Changes After Colorectal Surgery
This study measures how your heart rate varies after planned colorectal surgery to see if these changes can predict complications. Researchers will monitor your heart rhythm before and after your operation to understand whether certain patterns might warn of problems early.
NîmesAges 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+ - NCT07376733Recruiting
Breathing exercises for heart and lung health in multiple myeloma
This study looks at whether simple, guided breathing exercises can improve heart and lung health in people with multiple myeloma. It may help you feel stronger and manage side effects during treatment.
MadridAges 18 years+ - NCT07874750Recruiting
Slow breathing for stress relief in healthy young adults
This study tests whether a 6-week slow-breathing exercise program can lower stress, improve heart rate variability (a sign of healthy heart function), and fix shallow or irregular breathing patterns in healthy young adults between ages 18 and 25. It might help you feel calmer and more in control of your stress.
IstanbulAges 18–25 - NCT05950698Recruiting
Study of obesity and bariatric surgery with mental and social factors

Clermont-Ferrand, Auvergne-Rhône-AlpesAges 18 years+ - NCT07872098Recruiting
Breathing exercises for recovery after heart stent procedure
This study tests whether special breathing exercises (Pilates-style and diaphragmatic) can improve oxygen levels and heart health after a heart stent procedure. It may help patients recover better by strengthening their breathing.
RawalpindiAges 44–75 - NCT07867431Recruiting
Breathing exercises after heart stent procedure

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.
