Ventricular tachycardia

This trial tests whether a procedure called pulsed field ablation can safely treat ventricular arrhythmias—abnormal heart rhythms that can be life-threatening. About 30 people with frequent premature heartbeats or ventricular tachycardia will receive the treatment using a special…

This study tests whether a wearable monitoring system (ECG patch, temperature patch, and pulse oximeter) can reduce major heart complications in hospitalized patients with heart disease. About 1500 adults will be monitored either with standard care (vital signs every 4-8 hours) o…

This study tests a non-invasive radiation treatment called STAR for people with a dangerous fast heart rhythm caused by heart scarring. Instead of using medications or a catheter procedure, a single targeted dose of radiation is delivered to the scarred area. The goal is to see i…

This study tests a new technique called Dynamic Voltage Mapping (DVM) to better identify scar tissue in the heart that causes ventricular tachycardia (VT), a life-threatening heart rhythm. The approach uses catheters to create a personalized electrical map, aiming to guide ablati…

This study tests whether mirabegron, a drug typically used for overactive bladder, can reduce dangerous heart rhythms in people with heart disease. Twenty adults with an implanted defibrillator and frequent ventricular tachycardia will take the drug for two months. Researchers wi…

This study tests a new radiation treatment for people with a life-threatening fast heart rhythm called ventricular tachycardia that hasn't been helped by medication or prior procedures. About 24 adults with an implanted defibrillator will receive a single, targeted dose of radiat…

This study tests a device that uses extreme cold to destroy small areas of heart tissue causing ventricular tachycardia, a fast and dangerous heart rhythm. Up to 130 people with recurrent VT will receive the procedure and be followed for 6 months. The goal is to see if the treatm…

This early study tests a procedure that uses a catheter to ablate (destroy) a nerve near the heart, aiming to reduce signals that trigger ventricular tachycardia (VT), a dangerous fast heart rhythm. Ten adults with an implanted defibrillator (ICD) and recurrent VT will be enrolle…

This study looks back at the medical records of 300 people with arrhythmogenic cardiomyopathy who have an implantable cardioverter-defibrillator (ICD) and have had dangerous heart rhythms. Researchers want to count how often ICD-related problems occur, such as lead failure or ina…

This study follows 25,000 people referred to a specialized heart clinic with symptoms like chest pain or shortness of breath. Researchers will track which heart conditions are actually diagnosed and how patients are evaluated. The goal is to improve diagnostic accuracy and unders…

This study checks whether three common ECG-based methods can accurately locate where abnormal heart rhythms start in adults who had Tetralogy of Fallot repair. Researchers will pace the heart from known spots during a scheduled procedure and compare the predicted location to the …

This study looks back at medical records of 1500 adults hospitalized for acute myocarditis (heart muscle inflammation). The goal is to find out how often dangerous heart rhythms occur and what factors predict them. No new treatments are tested—researchers will use existing data t…

This study tests a machine learning device that uses heart tracings (ECG) to predict if a person will have another cardiac arrest after being revived. Researchers will first see if EMS providers find the device useful in simulated scenarios, then test its accuracy in 68 real pati…

This study aims to see if artificial intelligence can predict serious heart rhythm problems, like atrial fibrillation, after high-risk surgeries. Researchers will record ECGs from 300 adults before surgery and analyze over 200 heart cycle parameters to find the best prediction me…

This study will measure various biomarkers in 200 people with certain heart rhythm problems (ventricular tachycardia, premature ventricular contractions, and AVNRT) who are scheduled for a catheter ablation procedure. The goal is to see if these biomarkers are linked to the speci…

This study tests a small, sticky patch that records heart rhythms in hospitalized patients who need continuous monitoring. The patch sends data to a central system for real-time alerts and later review. Researchers want to see if it helps doctors make faster decisions about treat…

This study looks at whether people with certain heart rhythm disorders also carry genetic variants linked to a rare muscle condition called non-dystrophic myotonia. Researchers will review medical records of 570 participants and invite some for a neurological exam and electromyog…

This study tests new MRI and CT imaging methods to better identify scar tissue in the heart that causes a dangerous fast heartbeat called ventricular tachycardia (VT). About 15 adults with VT and heart disease will get these scans. The goal is to see if the scans can clearly show…

This study looks at 100 adults with frequent extra heartbeats (PVCs) to see if hidden heart inflammation (myocarditis) is the cause. Participants will get advanced heart scans and lab tests. The goal is to better understand the link and see if anti-inflammatory therapy helps thos…
