ARRHYTHMIA

This study is a worldwide registry that will follow 1,000 people who have a heart rhythm problem (arrhythmia) and are treated with the DiamondTemp ablation system. The goal is to see how often the heart rhythm stays normal one year after the procedure and to track any serious sid…

This study compares a continuous ECG patch (worn for days) to a handheld ECG device (used as needed) in 588 people who have symptoms of an irregular heartbeat but haven't been diagnosed yet. The goal is to see which device finds more heart rhythm problems and is more cost-effecti…

This study looks at how a child's quality of life changes after a procedure called transcatheter ablation, which corrects irregular heartbeats. About 200 children aged 5 to 17 who need this treatment will fill out questionnaires about their physical, emotional, social, and school…

This study is for people with heart failure who do not have a pacemaker or defibrillator. Researchers will use a small implanted device called BIOMONITOR IV to track heart rhythms and other body signals over time. The goal is to learn how often irregular heartbeats happen and to …

This study aims to find the genes that cause inherited heart and muscle diseases, such as cardiomyopathy, arrhythmia, and muscular dystrophy. Researchers will analyze DNA from patients and their families to identify mutations. The goal is to better understand these conditions, no…

This study is observing how well Medtronic heart devices (like pacemakers and defibrillators) work over time in 20,000 people with heart rhythm problems or heart failure. Researchers are tracking device survival and complications to improve future products. Participants must alre…

This study looks at how minimally invasive lung cancer surgery affects the heart's electrical activity. Researchers will monitor 100 adult patients before, during, and after surgery to see if temporary changes occur. The goal is to better understand heart stress from this procedu…

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…
