• Risk of malignant arrhythmias after acute coronary syndrome

  This study tracks how often dangerous heart rhythms occur in adults admitted for ACS and looks for patterns that might predict them.

  Recruiting Catharina Ziekenhuis Eindhoven · Eindhoven, North Brabant · NCT07824050

• Predict Arrhythmia Risk with Intelligent Software

  Researchers are testing AI-powered predictions to see if clinicians can spot patients at risk for dangerous heart rhythms using bedside ECG data.

  Recruiting Catharina Ziekenhuis Eindhoven · Eindhoven, North Brabant · NCT07792694

• Parasternal EV-ICD System Pivotal Study

  This study tests the Parasternal Extravascular ICD System in adults who need an ICD to see if it can safely provide defibrillation without traditional leads.

  Recruiting at 17 sites AtaCor Medical, Inc. · Scottsdale, Arizona and 34 other locations · NCT07324031

• Early double sequential defibrillation for cardiac arrest outside the hospital

  We test whether using two defibrillators in quick succession after the first failed shock helps adults with out‑of‑hospital cardiac arrest and a shockable rhythm survive more often than continuing standard single shocks.

  Recruiting at 9 sites Phase 2/3 Karolinska Institutet · Amsterdam and 13 other locations · NCT07174986

• Longitudinal Assessment of Cardiac MRI Microstructure in Patients and Healthy People

  This study tests advanced, non-contrast and extended clinical cardiac MRI techniques to see how heart tissue features differ between people with heart disease and healthy individuals.

  Recruiting The Cleveland Clinic · Cleveland, Ohio · NCT07081711

• Initial double sequential defibrillation for out-of-hospital ventricular fibrillation

  This trial will test whether using two defibrillators to give double sequential shocks first improves survival for adults with out-of-hospital cardiac arrest and a shockable rhythm.

  Recruiting St. Olavs Hospital · Trondheim · NCT06672159

• Evaluating different approaches to cardiac pacing in patients

  This study is testing different ways to place pacemakers in adults to see which methods work best and are safest for patients needing heart support.

  Recruiting at 31 sites University Hospital of Ferrara · Ferrara, FE and 30 other locations · NCT06324682

• Evaluating dexmedetomidine for treating electrical storm in patients

  This study is testing if a sedative called dexmedetomidine can help adults with electrical storm, which causes dangerous heart rhythms, by reducing these episodes and improving their recovery.

  Recruiting Phase 3 Ottawa Heart Institute Research Corporation · Rochester, Minnesota and 1 other locations · NCT06281977

• Effect of early nasal cooling on survival after cardiac arrest

  This study is testing if cooling patients right after a cardiac arrest can help them survive better and recover their brain function compared to standard care.

  Recruiting at 15 sites Karolinska Institutet · Graz and 16 other locations · NCT06025123

• Using Stellate Ganglion Block to Treat Arrhythmic Storm

  This study is testing if a special nerve block can help people having a severe heart rhythm problem called arrhythmic storm by reducing the number of shocks they need from a defibrillator.

  Recruiting at 36 sites Fondazione IRCCS Policlinico San Matteo di Pavia · Alessandria, AL and 37 other locations · NCT05720936

• Development of advanced MRI techniques for heart disease assessment

  This study is testing new MRI techniques to see how heart tissue differs between people with heart disease and healthy individuals to improve heart assessments.

  Recruiting The Cleveland Clinic · Cleveland, Ohio · NCT05654272

• Assessing the benefits of ICD implantation in patients with coronary artery disease after cardiac arrest

  This study is testing if getting an implantable defibrillator helps people with coronary artery disease who have survived a cardiac arrest feel better and live longer.

  Recruiting Copenhagen University Hospital, Rigshospitalet · Copenhagen · NCT04576130

• Evaluating low versus standard doses of epinephrine for out-of-hospital cardiac arrest

  This study tests whether giving a lower dose of epinephrine can help adults who have a cardiac arrest outside of the hospital more effectively than the standard higher dose.

  Recruiting at 9 sites Phase 4 Unity Health Toronto · Victoria, British Columbia and 8 other locations · NCT03826524

• Registry for implantable cardiac devices

  This study is tracking how well pacemakers and defibrillators work for people with heart rhythm problems to see if they can improve patient care and outcomes.

  Recruiting Heinrich-Heine University, Duesseldorf · Düsseldorf · NCT03360227

Quick answers

How many Ventricular Fibrillation clinical trials are recruiting right now?

14, as of November 12, 2026. We update this list each time we refresh our data from ClinicalTrials.gov.

Where are these trials running?

In 13 countries. The most sites are in United States (4 trials), Netherlands (4 trials), Italy (3 trials), Canada (2 trials), Germany (2 trials). Each study page lists its sites and which ones are recruiting.

What phases are they in?

Phase 4: 1, Phase 2/3: 1, Phase 3: 1. Trials with no phase listed are usually device, behavioural or observational studies.

How do I join one?

Open a study, check the "Is this trial a fit for you?" section, then contact the study team listed on the page. They will ask a few screening questions. Asking is free and does not commit you to anything. Talk it over with your doctor first.
