ARRHYTHMIA

This study is a worldwide registry that will follow 1,000 people who have a heart rhythm problem (arrhythmia) and are scheduled for a procedure using the DiamondTemp ablation system. The goal is to see how well the system stops the abnormal rhythm from coming back and to track an…

This study compares two portable heart monitors—a continuous patch worn on the chest and a handheld device used as needed—to see which one better detects arrhythmias (irregular heartbeats) in people who have symptoms but a normal in-clinic ECG. About 588 adults who can use a smar…

This study looks at whether a heart procedure called transcatheter ablation improves daily life for children aged 5 to 17 with arrhythmia. About 200 kids who need the procedure will fill out questionnaires about their physical, emotional, social, and school functioning before and…

This study follows 1,500 people with heart failure who already have an implantable defibrillator (ICD). The goal is to learn which patients are at highest risk of sudden cardiac death by looking at heart structure, electrical signals, genetics, and blood markers. This information…

This study will follow 10,000 people with heart conditions (like heart failure, heart attack, or bypass surgery) who are going through cardiac rehab at a clinic in Davos, Switzerland. Researchers will collect health data, blood samples, and patient reports to learn what helps peo…

This study enrolls 300 people with heart failure who do not have standard heart devices like ICDs or CRTs. Researchers use the BIOMONITOR IV, a small implant that tracks heart activity, breathing, and fluid levels remotely. The goal is to learn how often irregular heartbeats occu…

This study looks at how modern, minimally invasive lung cancer surgery affects the heart's electrical signals and stress levels. Researchers will monitor 100 adult patients before, during, and after surgery to see if any heart changes occur and if they are temporary. The goal is …

This study aims to find the genes and mutations that cause inherited heart conditions like cardiomyopathy and arrhythmia, as well as muscular dystrophy. Researchers will collect DNA samples from patients and their families, focusing on those with multiple affected relatives. The …

This study follows 20,000 people who have or will receive a Medtronic heart device (like a pacemaker or defibrillator) to see how long the devices last and how often problems occur. Participants have conditions such as irregular heartbeat, slow heart rate, or heart failure. The g…
