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 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…

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…
