Recruiting studies
- NCT05258422Enrolling by invitationPhase 2
Radiation ablation for recurring heart rhythm tachycardia
This study tests a targeted form of radiation therapy to stop a dangerous, repeat heart rhythm called ventricular tachycardia. It’s for people whose rhythm keeps coming back even after standard treatments like antiarrhythmic medications and prior heart procedure studies.
Montreal, QuebecAges 18 years+ - NCT05239364Recruiting
Ablation for an abnormal heart rhythm after prior AF surgery
This trial tests a procedure to “ablate” (treat) a specific fast heart rhythm in the upper chambers of the heart that happens after previous atrial fibrillation (AF) ablation or heart surgery. It may help by stopping the rhythm and reducing symptoms, while doctors check how well the targeted mapping and ablation work.
Hamburg, Free and Hanseatic City of HamburgAges 18 years+ - NCT05047198RecruitingPhase 3
Catheter procedures to stop dangerous heart rhythm episodes
This study compares two catheter-based procedures to treat ventricular tachycardia (VT), a fast, dangerous heart rhythm. It looks to see which approach works better at reducing repeat VT events in people with weakened heart pumping.
Ottawa, OntarioAges 55 years+ - NCT04520347Enrolling by invitation
Registry for heart rhythm ablation in VT or PVC
This study is a “registry,” meaning it collects information about people undergoing a procedure to treat abnormal heart rhythms like ventricular tachycardia (VT) or premature ventricular contractions (PVCs). It may help researchers better understand which patients benefit from the procedure and how it is done over time.
Phoenix, ArizonaAges Any age - NCT04271878Recruiting
Test breathing and blood-pressure response in POTS patients
This study measures how breathing patterns and heart rate/blood pressure change when you move from lying to standing in people with POTS. It may help researchers understand symptoms better and improve ways to manage them.
Calgary, AlbertaAges 18–60 - NCT03713866Recruiting
Imaging heart scar during ablation for certain fast heart rhythms
This trial uses special heart imaging during a catheter ablation to better map scar tissue that may be causing a dangerous fast heart rhythm (monomorphic ventricular tachycardia). It may help doctors target the problem more accurately during the procedure.
Halifax, Nova ScotiaAges 18–85 - NCT03049254Recruiting
Registry and blood/tissue study for certain sudden heart death causes
This study builds a registry and collection of samples to better understand families affected by sudden heart death and related heart rhythm problems that are not clearly caused by a heart attack. It may help researchers identify patterns and improve future care, and it offers a way for patients and families to contribute to research.
Rochester, MinnesotaAges Any age - NCT00409435RecruitingPhase 2
Pyridostigmine trial for postural tachycardia syndrome symptoms
This trial tests whether pyridostigmine helps people with postural tachycardia syndrome (POTS), which causes heart rate to rise when you stand up and can lead to unpleasant symptoms. You would be screened based on your tilt-table heart-rate response and your standing-related symptoms.
Rochester, MinnesotaAges 15–55 - NCT05236153Recruiting
Study of heart valve procedure in repaired Tetralogy of Fallot
This study looks at how a transcatheter pulmonary valve replacement works in people with repaired Tetralogy of Fallot or double outlet right ventricle. The goal is to better understand the heart’s anatomy and how it may affect the valve procedure.
Boston, MassachusettsAges Any age - NCT06324682Recruiting
Comparing heart pacemaker types for better treatment
This trial looks at different ways to pace the heart (like left, right, or both sides) to see which works best for people who need a pacemaker. If you have a heart condition requiring a pacemaker, this study may help find the safest and most effective option for you.
Ferrara, FEAges 18 years+ - NCT04186286RecruitingPhase 2
Testing propranolol vs ivabradine for POTS symptoms
This study compares two heart-rate medicines—propranolol and ivabradine—to see which better improves symptoms in people with POTS. It uses a “crossover” design, meaning you may try one medicine and then switch to the other.
Calgary, AlbertaAges 18–60 - NCT07849738Recruiting
Genetic testing after sudden cardiac death
This study looks at the DNA of young people who died suddenly without a clear cause, to find inherited heart conditions. If a genetic cause is found, close family members can be tested to learn their own risk and get preventive care.
São Paulo, São PauloAges 5–50 - NCT07824050Recruiting
Studying dangerous heart rhythms after a heart attack
This study looks at people who had a heart attack or cardiac arrest to find out which dangerous heart rhythms can happen afterward. The goal is to improve care and prevent future problems.
Eindhoven, North BrabantAges 18 years+ - NCT05835791Recruiting
Study of new ventricular arrhythmia patients getting ICD follow-up
This study looks at people who are newly diagnosed with a dangerous heart rhythm called ventricular tachycardia (VT) and who are getting an implantable cardioverter-defibrillator (ICD). It may help improve how patients are followed in the ICD clinic after the initial hospitalization.
Vancouver, British ColumbiaAges 18 years+ - NCT07792694Recruiting
Predicting dangerous heart rhythms with smart software
This study uses computer software to analyze heart rhythm recordings from patients in the hospital to predict dangerous irregular heartbeats (arrhythmias). It aims to improve early detection and care for patients with heart conditions.
Eindhoven, North BrabantAges 18 years+ - NCT06607471Recruiting
Study on non-ischemic heart muscle diseases
This study looks at different types of heart muscle diseases that are not caused by blocked arteries (non-ischemic cardiomyopathies). It aims to better understand how to diagnose, predict outcomes, and treat these conditions by gathering information from many patients over time.
Milan, MilanoAges 18 years+ - NCT04976348Recruiting
Heart monitoring registry for teens and adults with heart symptoms
This study registers people who are referred to cardiology or genetics for heart-failure–type symptoms or heart/cardiogenetic screening. It helps doctors understand how monitoring platforms may support diagnosis and follow-up.
Maastricht, LimburgAges 16 years+ - NCT07579026Recruiting
Breathing exercises for pregnant women with POTS
This study tests whether special breathing exercises can help pregnant women with POTS (a condition where your heart races when you stand up). POTS causes dizziness, lightheadedness, and fainting, and this trial aims to see if breathing retraining makes these symptoms better during pregnancy.
Sialkot, Punjab ProvinceAges 19–35 - NCT06730607Recruiting
Predicting heart rhythm problems after myocarditis
This study uses heart MRI scans to predict who might develop dangerous heart rhythms after recovering from myocarditis. It aims to find better ways to monitor patients and prevent emergencies.
Rozzano, MilanAges 18 years+ - NCT06730464Recruiting
Predicting dangerous heart rhythms in non-ischemic heart disease
This study uses heart MRI scans to predict who might develop dangerous heart rhythms. It's for people with certain types of non-ischemic heart disease who have already had an MRI with contrast.
Milan, ItalyAges 18 years+ - NCT07556133Recruiting
Comparing two sedation medicines during cataract surgery
This study tests two sedation medicines (dexmedetomidine and propofol) used to keep patients calm and comfortable during cataract surgery. Researchers want to see which combination works best and is safest for this common procedure.
BeirutAges 18 years+ - NCT07503769Enrolling by invitation
Dual-energy cardiac ablation for ventricular arrhythmia
This study tests a new method using two types of energy to treat a fast heartbeat coming from the lower heart chambers. It is designed for people whose symptoms have not been controlled by medication and who do not have other serious heart conditions.
Ningbo, ZhejiangAges 18–75 - NCT07501299Recruiting
