Recruiting studies
- NCT06744244Recruiting

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 - 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+ - 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+ - 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+ - NCT03232918RecruitingPhase 4
Oxytocin effects on baby’s heart rate during labor
This study looks at how oxytocin (a labor-inducing/strengthening medicine) may affect your baby’s heart rate during labor. It also compares what happens when labor pain relief is given as a spinal/epidural injection.
Iowa City, IowaAges 18–55 - 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.

Ivabradine to slow heart rate in sepsis ICU patients
This study tests whether ivabradine (a heart-rate medicine) can improve blood flow and other vital measurements in adults with sepsis in the ICU. It may help by lowering a fast heart rate when blood pressure is already being supported.
Guangzhou, GuangdongAges 18 years+ - 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 - 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+ - NCT07297901Enrolling by invitation
Breathing app study for migraine relief
