Recruiting studies
- 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+ - NCT06943365Recruiting
Role of Anti-TREK-1 Antibodies in Sudden Cardiac Arrest Without Blockage
This study looks for a specific type of antibody (called anti-TREK-1) in the blood of people who have had a sudden cardiac arrest without a clear cause. It aims to understand if these antibodies play a role in the condition, which might help with future diagnosis or treatment.
Vancouver, British ColumbiaAges 18 years+ - NCT04576130Recruiting
ICD study after cardiac arrest from an abnormal heart rhythm
This study looks at an implantable defibrillator (ICD) strategy in people who survived a cardiac arrest caused by an abnormal rhythm (ventricular fibrillation or ventricular tachycardia). It aims to reduce the risk of another dangerous rhythm after the blocked heart arteries are fully treated.
CopenhagenAges 18 years+ - NCT07405229RecruitingPhase 4
Medical treatment for idiopathic ventricular fibrillation patients
This study tests medical treatments for people who survived a cardiac arrest with a specific heart rhythm problem called idiopathic ventricular fibrillation. If your cardiac arrest was likely from a heart issue but not from clogged arteries, you might help find better treatments.
Copenhagen, Dr.Ages 18 years+ - 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+ - NCT07116525Recruiting
Study of heart mapping for abnormal rhythms
This trial tests a special catheter to map abnormal heart rhythms like ventricular tachycardia or atrial fibrillation. It may help patients who need a procedure to find and treat the source of these fast or irregular heartbeats.
BrugesAges 18 years+ - NCT07324031Recruiting
Study of a new under-the-skin defibrillator (the Parasternal EV-ICD)
This study tests a new type of defibrillator that goes underneath the skin, near your breastbone, to protect against dangerous heart rhythms. It may be an option if you need an ICD but haven't had certain prior chest surgeries or devices.
Scottsdale, ArizonaAges 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+ - NCT06575881Recruiting
Genetic heart muscle disease and heart rhythm study
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+ - NCT07081711Recruiting
Testing new heart MRI technology in volunteers
This study is testing a new way to take pictures of the heart using MRI. It is looking for healthy volunteers to help make sure the technology works correctly.
Cleveland, OhioAges 18 years+ - NCT03826524RecruitingPhase 4
Finding the best epinephrine dose after EMS-treated cardiac arrest
This study compares two epinephrine doses during the emergency treatment of out-of-hospital cardiac arrest. It aims to find a dose that works better and more safely for people who are in a shockable heart rhythm when paramedics arrive.
Victoria, British ColumbiaAges 18 years+ - NCT05654272Recruiting
Testing CIRC imaging technology for people with heart problems
This study is developing and testing CIRC technologies using heart imaging. You may be able to join if you’re an adult with cardiovascular (heart) disease and can safely have the MRI scans.
Cleveland, OhioAges 18 years+ - NCT05720936Recruiting
Nerve block treatment for dangerous heart rhythm episodes
This trial looks at a procedure called a stellate ganglion block to calm dangerous, repeated heart rhythm attacks that haven’t improved with standard medicines. It may help reduce how often and how long these episodes last while you’re in the hospital.
Alessandria, ALAges Any age - NCT06071910Recruiting
Emergency balloon for cardiac arrest outside hospital
This trial tests if placing a special balloon in the main blood vessel (aorta) can help restart the heart after a cardiac arrest that happens outside the hospital. It is for patients who have not gotten a return of pulse even with CPR.
NorwichAges 18–80 - NCT06964152Enrolling by invitation
AI-Guided Mapping for Ventricular Tachycardia Ablation
This trial uses artificial intelligence to analyze heart images and guide doctors during a procedure to stop dangerous fast heart rhythms called ventricular tachycardia.
La Jolla, CaliforniaAges 21–90 - NCT03360227Recruiting
Registry after heart device implantation planning
This is a registry study that records information from people before they get a heart-related device implanted. It may help doctors understand how the team’s tests and planning relate to the procedure and outcomes later on.
DüsseldorfAges 18–80 - 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+ - NCT04088071Recruiting
Ablation for heart rhythm problems using a specific technology
This study looks at how well catheter ablation works for treating certain heart rhythm disorders (like atrial fibrillation or ventricular arrhythmias) using a specific brand of catheters. The aim is to gather real-world data to better understand the procedure's outcomes.
Birmingham, AlabamaAges 18 years+ - NCT06745778Recruiting
Study of heart device signals in patients with left bundle pacing
This study looks at the electrical signals recorded by a special type of pacing lead placed in the heart's left bundle branch. It aims to understand how these signals change over time in people who already have an ICD or CRT-D device.
Wenzhou, ZhejiangAges 18 years+ - NCT07428967Recruiting
Pacemaker after heart procedure for atrial fibrillation
This trial tests a new type of pacemaker for people with atrial fibrillation who are scheduled for a procedure that disconnects the heart's natural electrical pathway. It may help improve symptoms and heart function.
HagenAges 18 years+ - NCT07775976Enrolling by invitation
Whole-heart checkup with a wearable heart monitor
This study looks at how well a wearable heart monitor and special software can check the health of your whole heart and assess your risk of future heart problems. It may help doctors create more personalized care plans.
Pasadena, CaliforniaAges 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+ - NCT07220525Recruiting
Sleep and heart rhythm study for people with sleep apnea device
This study looks at how turning off your sleep apnea device for short periods affects your heart rhythm, especially if you have a condition like atrial fibrillation. It may help understand the link between sleep and heart health.

Common questions
- Are there clinical trials for ventricular fibrillation?
- Yes. Clin2 currently lists 37 recruiting ventricular fibrillation studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a ventricular fibrillation trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a ventricular fibrillation trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
