Recruiting studies
- NCT05594368RecruitingPhase 1
Test targeted radiation to treat recurrent ventricular tachycardia
This trial studies a radiation approach (called stereotactic body radiation therapy, or SBRT) to treat ventricular tachycardia (a dangerous heart rhythm) that keeps coming back. It aims to reduce the rhythm episodes in people who have already tried catheter ablation (a procedure to cauterize rhythm sources) or cannot have it.
OstravaAges 18 years+ - NCT05696522Recruiting
Radiation to treat hard-to-control dangerous heart rhythm
This trial tests a focused type of radiation to treat ventricular tachycardia (VT) that keeps coming back despite other treatments. It may help people who cannot (or do not want to) have the usual catheter procedure to fix the rhythm.
LondonAges 18–85 - NCT05765175Recruiting
Radioablation versus repeat ablation for hard-to-treat VT
This trial compares a heart procedure using targeted radiation (called radioablation) to a repeat catheter ablation for people with high-risk, hard-to-control ventricular tachycardia (VT). It aims to find which approach is safer and works better after standard ablation and amiodarone have not stopped the abnormal rhythm.
Los Angeles, CaliforniaAges 18 years+ - NCT06292104Recruiting
Understanding POTS: A study on heart rate and standing
This study looks at how the body controls heart rate and blood flow in people with POTS (a condition that causes dizziness and a fast heart rate upon standing). It helps researchers understand POTS better by comparing patients with healthy volunteers.
Dallas, TexasAges 14 years+ - NCT06294028Recruiting
Ablation vs Defibrillator for Well-Tolerated Fast Heartbeat
This study compares two treatments for a fast heartbeat called ventricular tachycardia in people with prior heart attacks and relatively preserved heart function: one uses heat energy (ablation) to fix the electrical problem, and the other places an implantable defibrillator that shocks the heart to restore normal rhythm. The goal is to find which approach works better for people whose symptoms are well-tolerated.
Toulouse, FranceAges 18–90 - NCT06360939Recruiting
Radiation or ablation for ventricular tachycardia in heart disease
This trial compares two treatments—radiation therapy or catheter ablation—for people with structural heart disease who have a type of fast heart rhythm called ventricular tachycardia. It aims to see which approach works better to prevent repeat episodes.
WestmeadAges 18 years+ - NCT06505668Recruiting
Comparing two heart rate medicines for clozapine users
This study compares two medications (atenolol and ivabradine) to see which one better controls a fast heart rate (tachycardia) in people with treatment-resistant schizophrenia who are taking clozapine. The goal is to find a safer way to manage this side effect.
Bhubaneswar, OdishaAges 18–60 - NCT06575881Recruiting

This study looks at the risk of a fast heart rhythm (ventricular tachycardia) in people with genetic heart muscle diseases. It tests whether having a specific genetic change affects the success of a heart ablation procedure.
Nashville, TennesseeAges 18 years+ - NCT06661278Recruiting
Exercise testing in kids with inherited heart rhythm conditions
This study looks at how children with certain genetic heart rhythm problems, like long QT syndrome, respond to exercise. It may help doctors understand how to better manage these conditions.
LondonAges 6–16 - NCT06669299Recruiting
A heart-rhythm test after ablation to guide next steps
This trial uses a non-invasive stimulation test (NIPS) about a week after a successful ablation procedure for ventricular tachycardia (VT). It aims to see if the test can help doctors decide on further treatment to prevent the fast heart rhythm from returning.
Milan, ItalyAges 18 years+ - NCT06703489Recruiting
New catheter for ventricular tachycardia
This trial tests a new catheter system (Sphere-9 and Affera) to treat a fast, dangerous heartbeat called ventricular tachycardia (VT) in people with heart scarring. It aims to see if this system is safe and effective at stopping VT, especially if past treatments haven't worked.
Boston, MassachusettsAges 18–85 - NCT06281977RecruitingPhase 3
Dexmedetomidine for electrical storm in the ICU
This trial tests if a medication called dexmedetomidine (a sedative that can also stabilize heart rhythm) helps calm electrical storms—dangerous, repeated episodes of fast heartbeats. It is for people in the intensive care unit who are experiencing this emergency.
Rochester, MinnesotaAges 18 years+ - NCT06717685RecruitingPhase 3
Adenosine vs Verapamil for rapid heart rate
This trial compares two medicines, adenosine and verapamil, to see which works better for stopping a sudden fast heart rhythm called SVT. If you have an episode of SVT that is stable enough to not need emergency shock treatment, you may be able to join.
Lahore, Punjab ProvinceAges 18–70 - NCT06743789Recruiting
Radiation therapy for ventricular tachycardia: one or three sessions
This trial tests whether a single session of targeted radiation (radioablation) is as effective as three sessions for treating a dangerous heart rhythm called ventricular tachycardia in people with heart muscle disease. It's for those who continue to have episodes despite medication and catheter ablation.
New York, New YorkAges 18–90 - NCT06744530Recruiting
Heart radiation therapy for ventricular tachycardia II study
This study tests if targeted radiation therapy can help people with a serious heart rhythm problem called ventricular tachycardia (VT) that hasn't gotten better with other treatments. It aims to see if this approach can reduce dangerous heart rhythm episodes.
LeuvenAges 18 years+ - NCT06891456Recruiting
Pulsed field ablation for ventricular tachycardia after heart attack
This trial tests a new type of energy (pulsed field ablation) to treat a fast heart rhythm called ventricular tachycardia that happens after a heart attack. The goal is to stop the dangerous rhythm without damaging nearby healthy tissue.
Cleveland, OhioAges 18 years+ - NCT06936319Recruiting
Body movements for POTS symptom control
This study tests simple body movements (like squeezing your legs or squatting) to see if they help control POTS symptoms. It may offer a non-drug way to manage dizziness and fast heart rate when standing.
