ARRHYTHMIAS, CARDIAC

This study tests if a non-invasive radiation treatment (SBRT) can reduce dangerous heart rhythms better than the standard catheter ablation procedure in 60 people with advanced heart disease. Participants will be randomly assigned to receive either radiation or catheter ablation.…

This study tests whether a personalized, sensor-based exercise program can reduce symptoms in 120 adults with atrial fibrillation (AFib). Participants will use a digital tool to guide their activity over several weeks. The goal is to see if this approach improves how patients fee…

This study looks at two ways to treat atrial tachycardia (a fast heart rhythm) that happens after atrial fibrillation treatment or heart surgery. Researchers will use a new ultra-high-density mapping technique to better understand the heart's electrical signals. They want to see …

This study at Stanford University is observing 200 people with persistent atrial fibrillation (AF) who are already scheduled for a heart procedure. Researchers will map the heart's electrical signals to see if the size of organized areas predicts success from ablation. No new tre…

This study looks at whether a new mapping tool called vMap can help doctors perform heart ablations more quickly and effectively. Researchers will compare procedure times and success rates in 110 adults with irregular heartbeats. The goal is to see if vMap improves workflow and o…

This study collects blood and tissue samples from 2,000 adults with or without heart rhythm problems (arrhythmias) to find genetic variants linked to these conditions. Participants include those with arrhythmias, their family members, and healthy controls. No treatment is given; …

This study is following 8,000 people with heart rhythm problems who are getting a standard procedure called catheter ablation. The goal is to check how safe and effective the approved devices are in everyday use. Researchers will track complications and how well the procedure wor…

This study enrolls 500 people who have had a stroke and also have atrial fibrillation (an irregular heartbeat). Researchers want to understand why some strokes happen even when patients take blood thinners. They will collect blood samples and heart ultrasound images, then follow …

This study at Stanford University is testing whether a computer program can help doctors better treat atrial fibrillation, a common heart rhythm problem. About 120 adults with AF who are scheduled for a procedure called ablation will take part. The researchers will use machine le…

This study is testing a digital app called VIRTUES to help people with heart conditions manage their health at home. The app provides personalized recommendations on medications, diet, exercise, and more. Researchers will enroll 2000 participants to use the app for one month and …
