ARRHYTHMIA

This study looks at whether using a CPAP machine for sleep apnea after a heart procedure (catheter ablation) can help prevent atrial fibrillation from coming back. About 658 adults with both conditions will be randomly assigned to use CPAP for a year or receive usual care. The go…

This study compares two types of portable heart monitors in people who have symptoms of an irregular heartbeat (arrhythmia) but whose standard heart test was normal. About 588 participants will wear either a continuous ECG patch or use a handheld ECG device for one month. The goa…

This study looks at how a child's quality of life changes after a procedure called transcatheter ablation, which treats abnormal heart rhythms. Researchers will ask 200 children aged 5 to 17 and their parents to fill out questionnaires about physical, emotional, social, and schoo…

This study is not testing a drug or treatment. Instead, researchers are using artificial intelligence to analyze electrocardiogram (ECG) data from over 127,000 people. The goal is to create computer models that can quickly and accurately predict life-threatening heart rhythm prob…

This study monitors how long Medtronic heart devices (like pacemakers) last and how often they have problems. It includes up to 20,000 people who have or will get one of these devices. The goal is to collect real-world data to improve future device safety and performance.

This study follows 1500 people who already have an implantable cardioverter-defibrillator (ICD) to prevent sudden cardiac death. Researchers will track heart function, genetics, and blood markers to find better ways to predict who is at highest risk. The goal is to improve how do…

This study will follow 10,000 people who come to a clinic in Davos, Switzerland for cardiac rehabilitation after a heart attack, surgery, or other heart problem. Researchers will collect health data, blood samples, and genetic information to understand what helps people recover b…

This study looks at how modern, minimally invasive lung cancer surgery affects the heart's electrical signals. Researchers will monitor 100 adults before, during, and after surgery to see if temporary changes occur. The goal is to better understand the heart stress caused by the …

This study aims to find the genes that cause inherited heart and muscle diseases like cardiomyopathy, arrhythmias, and muscular dystrophy. Researchers will collect blood samples from up to 2,000 patients and their families to look for genetic mutations. The goal is to better unde…

This study is testing a special heart monitor, the BIOMONITOR IV, in 300 people with heart failure who also have irregular heartbeats. The device tracks heart activity, fluid levels, and breathing patterns to see if it can predict when heart failure gets worse. Researchers hope t…
