Ventricular tachycardia

This trial tests whether a wearable ECG patch called MEMO Patch Plus can detect clinically significant arrhythmias in adults hospitalized with acute heart failure. Participants wear the patch for up to 14 days in the hospital and again for up to 14 days after discharge. The study…

This trial tests whether a new physical technique, the reverse vagal maneuver, can restore normal heart rhythm in adults with paroxysmal supraventricular tachycardia (PSVT) more effectively than the standard modified Valsalva maneuver. Participants are randomly assigned to one of…

This study tested whether using a CT scan before heart ablation can make the procedure faster and safer for people with ventricular tachycardia, a fast heart rhythm that can be life-threatening. 119 adults who had a prior heart attack and an implanted defibrillator were randomly …

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 study tested a wearable defibrillator patch (the Jewel) in 18 adults who were already scheduled for a heart procedure. The patch was used to deliver a shock to stop dangerous heart rhythms that could lead to sudden cardiac arrest. The goal was to see how often the patch coul…

This trial tested a new ablation catheter (DiamondTemp) against the current standard (Tacticath/Tactiflex) for treating ventricular tachycardia (VT), a life-threatening fast heart rhythm. 61 adults with VT who needed ablation took part. The goal was to see if the new catheter is …

This study tested a new freezing method (cryoablation) to treat a fast, dangerous heart rhythm called ventricular tachycardia. 64 adults who had not responded well to medication took part. The goal was to see if freezing the small area causing the problem could safely stop the rh…

This study tested whether a single dose of dantrolene, a muscle relaxant, could reduce the risk of dangerous heart rhythms in 68 people with structural heart disease who were scheduled for a procedure to treat ventricular tachycardia. Participants received either dantrolene or a …

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 study tested a new computer simulation, called a 'virtual heart,' to help doctors find the best spots to burn heart tissue (ablation) in patients with ventricular tachycardia (VT) caused by prior heart attacks. Ten adults with VT and scarred heart muscle were enrolled. The a…

This study tested whether using cardiac MRI to guide ablation (a procedure that destroys small areas of heart tissue) can improve outcomes for people with ventricular tachycardia, a dangerous fast heart rhythm. 104 adults with structural heart disease were randomly assigned to on…

This study tested a nasal spray called etripamil for people with a condition that causes sudden rapid heartbeats (PSVT). Participants, who had been in earlier studies, used the spray themselves at home to stop an episode. The main goal was to see if it was safe and easy to use ou…

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 study tested whether a CT scan before a heart procedure could help doctors better target the source of a dangerous heart rhythm called ventricular tachycardia. 23 people who had a prior heart attack and needed catheter ablation took part. The approach aimed to see if using C…

This study used computer simulations to compare three types of radiation (photons, protons, and carbon ions) for treating a dangerous heart rhythm called ventricular tachycardia. Researchers created treatment plans for 23 patients who were already scheduled for standard catheter …

This study tested whether a special pacing technique in the heart's right ventricle can more accurately predict where certain rapid heartbeats originate, compared to standard ECG criteria. Researchers enrolled about 200 patients undergoing catheter ablation for ventricular arrhyt…

This completed study looked at 60 heart failure patients with reduced pumping function and dangerous heart rhythms. Researchers compared metabolic profiles between those with ischemic (blocked arteries) and non-ischemic (other causes) heart disease. By analyzing blood samples, th…

This study looked at 537 people with myotonic dystrophy type 1 to understand their risk of serious heart rhythm problems, including sudden cardiac arrest. Researchers tracked participants for two years to see how often these events happened and what factors might predict them. Th…
