ARRHYTHMIAS, CARDIAC

This study tests whether a more targeted ablation approach, guided by advanced heart mapping, can reduce the return of atrial tachycardia in people who have already had treatment for atrial fibrillation or heart surgery. About 100 adults with stable, map-able atrial tachycardia w…

This study tests a digital app called VIRTUES that helps people with heart conditions manage their health from home. The app provides personalized recommendations for medications, diet, exercise, and more. Researchers will enroll 2,000 patients to see if the app is easy to use an…

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

This study tests if a personalized, app-based exercise program can reduce symptoms like heart fluttering and shortness of breath in people with atrial fibrillation (AFib). Researchers will enroll 120 adults with AFib who are already somewhat active. Participants will use a sensor…

This study looks at the heart signals of 200 people with atrial fibrillation (AF) to understand why some respond better to a procedure called ablation. Researchers will map organized electrical areas in the heart and see if larger areas predict success. The goal is to help doctor…

This study will follow 8,000 people with heart rhythm disorders who are scheduled for a standard catheter ablation procedure using approved Biosense Webster devices. The goal is to collect real-world data on how safe and effective these devices are during routine use. Participant…

This study looks at 500 people who have had a stroke and also have atrial fibrillation (an irregular heartbeat). The goal is to understand why some people still have strokes even when taking blood thinners. Researchers will collect blood samples and heart ultrasound images to fin…

This study collects blood and tissue samples from up to 2,000 adults with or without heart rhythm problems (arrhythmias) to find genetic links. Researchers will analyze DNA to understand why some people develop arrhythmias. No treatment or medication is given—this is a research-o…

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…
