Ventricular tachycardia (VT)

This study is testing a new device called the Sphere-9 catheter, used with the Affera mapping system, to treat ventricular tachycardia (VT) — a fast, dangerous heart rhythm. The procedure uses heat to destroy small areas of scarred heart tissue that cause the abnormal rhythm. The…

This trial tests whether a non-invasive mapping system called VIVO can help doctors locate the source of a dangerous heart rhythm called ventricular tachycardia (VT) before an invasive procedure. Patients with structural heart disease who need catheter ablation will be randomly a…

This study follows 50 patients with ventricular tachycardia that hasn't responded to standard treatments. They receive a single, high-dose radiation treatment (STAR) aimed at the heart tissue causing the abnormal rhythm. Researchers will track how well the treatment controls the …

This study looks at people with an implanted defibrillator who had a successful first procedure to fix a dangerous fast heart rhythm (ventricular tachycardia). A few days later, they get a non-invasive heart stimulation test. If the test triggers the rhythm again, patients are ra…

Researchers are testing a targeted ablation method for people with structural heart disease who have ventricular tachycardia, a dangerous fast heart rhythm. The procedure maps conducting channels inside heart scar tissue by pacing many sites, then uses radiofrequency energy to bl…

People admitted for acute coronary syndrome, which includes heart attacks and unstable angina, face a higher risk of dangerous heart rhythms such as sustained ventricular tachycardia and ventricular fibrillation. Hospitals monitor these patients, but the exact rate of these rhyth…

This study tests whether artificial intelligence can use continuous ECG data to predict and detect life-threatening heart arrhythmias in patients admitted with acute cardiac illness. Researchers will analyze stored ECG data from 3000 adult patients to see if AI models can forecas…

This international study looks at data from thousands of patients who had ablation procedures for ventricular tachycardia or premature ventricular complexes—heart rhythm problems. The goal is to understand how often severe complications like stroke, cardiac arrest, or major bleed…

This observational study will follow 1,500 adults with ventricular tachycardia (VT) to see how well different treatments work over the long term. Participants will receive either catheter ablation or non-ablation management (including drugs or an implantable defibrillator). The g…

This study is a registry that will follow 4,000 people in China who are having a procedure called catheter ablation to treat atrial fibrillation or ventricular tachycardia. The goal is to see how well the procedure works over the long term and how safe it is. Participants will be…

This observational study looks at how signals from a left bundle branch pacing lead change during daily activities and overdrive pacing in 50 people with an ICD or CRT-D. Researchers want to see if these leads can accurately detect ventricular tachycardia or fibrillation. Partici…

This registry collects information from 1,000 patients who have had or will have a heart rhythm procedure at University Hospital Düsseldorf. The goal is to track safety and success of these standard procedures in everyday care. No new treatments are being tested; instead, researc…
