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+ - NCT07545512Recruiting
Finding heart attack risk markers in moderate heart weakness
This study helps doctors identify which heart attack survivors with moderate heart weakness are at highest risk of sudden cardiac death. Researchers will collect health information and heart imaging over 5 years to find early warning signs.

French cohort study of an extra-vascular ICD
This study follows patients who receive a new type of implantable defibrillator that sits outside the heart and blood vessels. It aims to collect information about how well the device works and how safe it is over time.
ParisAges Any age - NCT04921501Recruiting
Testing a detailed heart tracing to evaluate rhythm risks
This study checks a more detailed kind of heart recording (ECG) using many small sensors to better measure electrical rhythm problems. It may help doctors refine how they assess risk in people with serious or suspected dangerous heart rhythm issues.
Clermont-FerrandAges 14 years+ - NCT07541092Recruiting
Optrell Catheter for Heart Rhythm Problems from Papillary Muscles
This study compares how well a special heart mapping catheter (Optrell) works in treating irregular heartbeats that start in specific heart muscle areas called papillary muscles. If you're having frequent or bothersome extra heartbeats, this trial may help you get a procedure your doctor already recommends.
New Hyde Park, New YorkAges 18–75 - NCT07501299Recruiting
HeartBeam ECG Registry for heart monitoring
This registry collects ECG data from people who are already getting an ECG for their heart health. It uses a device called HeartBeam to see if it works as well as the standard ECG machine.
Pittsburgh, PennsylvaniaAges 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 - NCT07491237Recruiting
Heart rhythm and function study
This study looks at how heart rhythm problems affect heart function. It may help doctors better understand and treat these conditions.
RomaAges 18 years+ - NCT07444372Recruiting
Starting CPAP therapy after atrial fibrillation ablation
This study tests whether starting CPAP therapy soon after a heart procedure called catheter ablation helps people with sleep apnea and atrial fibrillation (an irregular heartbeat) recover better and stay in normal rhythm. CPAP is a machine that helps keep your airway open while you sleep.
Beijing, Beijing MunicipalityAges 18–75 - 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+ - NCT07425132Recruiting
Non-invasive heart mapping for congenital heart disease
This trial tests a new, non-invasive way to create detailed 3D maps of the heart's electrical activity in people with congenital heart disease. It aims to help guide procedures like heart catheterization or device implantation, potentially making them safer and more personalized.
Madrid, MadridAges 18–80 - NCT06157437Recruiting
Focal pulse ablation for atrial flutter
This study tests a new device that uses focused pulses of energy to treat a common type of fast heartbeat called typical atrial flutter. It aims to see if this approach is safe and effective for people who have had at least one episode in the past 6 months.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07407790Recruiting
Smartphone heart check after stroke
This study tests whether using a smartphone app to check your heart rhythm after a stroke can find hidden atrial fibrillation (an irregular heartbeat). If you had a recent stroke or TIA and are not already on blood thinners, you may be able to help doctors detect and prevent future strokes.
KristiansandAges 18 years+ - NCT07388108Recruiting
Predicting heart rhythm problems after heart surgery
This trial studies whether measuring how the upper chambers of the heart work together can help predict dangerous heart rhythms after heart surgery. If you are in normal heart rhythm and not having mitral valve surgery, this study may help doctors better prevent complications.
Mendoza, MendozzAges 18–80 - NCT07374263Recruiting
Do heart rhythm drugs pose risks in hospital?
This study looks at whether certain medications that can affect heart rhythm (QT-prolonging drugs) are linked to serious heart problems in adults who were hospitalized. It includes patients admitted to St. Joseph's Healthcare Hamilton or other GEMINI hospitals between 2017 and 2025.
Hamilton, OntarioAges 18 years+ - NCT07353710Recruiting
Testing a new imaging system during heart ablation
This study tests a new imaging system (CHORUS IDx) that uses 2D ultrasound pictures to help doctors during a heart ablation procedure. It may help guide the procedure more safely.
MerewetherAges 18 years+ - NCT07336225Recruiting
CMR Study for Heart Device Patients
This study looks at people who already had a heart MRI before getting a pacemaker, defibrillator, or other heart device. It aims to learn how MRI results might predict long-term outcomes for these patients.
BeijingAges 18 years+ - NCT07271238Recruiting
Study of a new imaging system for heart ablation
This study tests a new imaging system (VERAFEYE) that helps doctors guide catheter ablation, a procedure to fix irregular heartbeats like atrial fibrillation. It aims to see if the system makes the procedure safer or more effective.
SplitAges 18 years+ - NCT07276139Recruiting
Heart device experience and outcomes study
This study collects information from people who have a heart device (like a pacemaker) to learn how these devices work in real life and how they affect patients. By joining, you help doctors improve care for future patients.
Canberra, Australian Capital TerritoryAges 18 years+ - NCT06898307Recruiting
Genetic test study for inherited heart rhythm conditions
This study uses genetic testing to better diagnose, predict, and manage inherited heart rhythm diseases. It is designed for patients at the University of Ferrara's Cardiogenetic Center who have a confirmed genetic heart condition.
FerraraAges Any age - NCT05521451Recruiting
Study for adults with heart rhythm problems
This trial is a “clinical cohort” study, meaning it follows adults with certain heart rhythm issues to understand them better. Your participation may help researchers learn what to expect and how best to support people over time.
HamburgAges 18 years+ - NCT06272396Recruiting
Testing a smartwatch to record heart rhythms
This study is testing whether a connected watch (like a smartwatch) can accurately record your heart's electrical activity (an ECG) during a hospital stay or clinic visit. If it works well, it could make checking your heart easier and more convenient.
PessacAges Any age - NCT06906432Recruiting
Brain-Heart Injury After Brain Bleed Study
This study looks at how a brain bleed can affect the heart. Researchers hope to understand the link between brain and heart injury to help improve care for people who have had a brain bleed.

Common questions
- Are there clinical trials for arrhythmia?
- Yes. Clin2 currently lists 163 recruiting arrhythmia 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 arrhythmia 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 arrhythmia 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.
