Ventricular arrythmia

This early study tested a new device called the FieldForce™ Ablation System in 34 people with ventricular arrhythmias (dangerous heart rhythms). The device uses pulsed electric fields to destroy the small areas of heart tissue causing the problem. The main goal was to see if the …

This pilot study tested a procedure called bilateral sympathectomy, which cuts certain nerves to the heart, in 45 Chagas disease patients with implantable defibrillators (ICDs) who had frequent dangerous heart rhythms. Participants were randomly assigned to receive the nerve-cutt…

This completed study tested a new type of implantable defibrillator (EV ICD) in 14 Japanese patients with dangerous heart rhythms. The device is placed under the skin, outside the heart and blood vessels, to deliver a shock if a life-threatening rhythm occurs. Researchers checked…

Researchers are testing whether a wearable armband called HeartWatch can record heart rhythm data as well as standard Holter and event monitors. Adults who need extended heart rhythm monitoring wear the armband alongside a standard device for up to three days. The study checks wh…

This study tests whether wearing a heart monitor for 14 days can detect dangerous heart rhythms in people with mitral valve prolapse (a common heart valve condition) better than the usual 24-hour test. About 60 adults with MVP will wear a patch monitor for two weeks. The goal is …

This study looked at whether it's safe to skip the defibrillation test when implanting a subcutaneous implantable cardioverter-defibrillator (S-ICD). The test involves purposely triggering a dangerous heart rhythm to make sure the device can stop it. About 965 people took part. T…

This pilot study enrolled 5 people with hypertrophic cardiomyopathy who needed an implantable cardioverter defibrillator (ICD) but did not require pacing. Participants were randomly assigned to receive either a subcutaneous ICD (placed under the skin) or a transvenous ICD (with l…

This study looked at 72 healthy male triathletes aged 20-54 who competed in a long-distance triathlon. Researchers checked heart function and rhythm before, during, and after the race to see if intense exercise causes temporary heart strain or irregular beats. The goal was to bet…
