OsloAges 18 years+ - NCT06250712Recruiting
Home ECG monitoring for unexplained heart symptoms
This study tests whether using a handheld ECG device at home can help monitor and detect heart rhythm problems in people with unexplained palpitations or dizziness. Participants will use a smartphone-connected device to record their heart's electrical activity and improve diagnosis.
Gwangju, Dong-gu Jaebongro 42Ages 19 years+ - NCT06164808Recruiting
Comparing a wearable heart monitor to a standard Holter monitor
This study compares a new wearable heart monitor (HeartWatch) that you wear on your left bicep to the standard Holter monitor. It aims to see if the HeartWatch is as good at recording your heart's rhythm over 24-48 hours, so you might have a more comfortable option for heart monitoring.
Calgary, AlbertaAges 22 years+ - NCT05724121Recruiting
Study heart rhythm changes during BTK or venetoclax treatment
This observational study tracks how your heart rhythm (heartbeat pattern) changes while you take a BTK inhibitor or venetoclax. It may help doctors better understand heart rhythm risks in people receiving these cancer-related medicines.
Bethesda, MarylandAges 18–110 - NCT05510167Recruiting
How quitting alcohol affects heart rhythm after ablation
This study looks at whether stopping alcohol after a heart procedure called catheter ablation helps prevent irregular heartbeats from coming back and improves your thinking and quality of life.
Austin, TexasAges 18–85 - NCT05439031RecruitingPhase 2
Stereotactic radiation to reduce recurrent dangerous heart rhythm episodes
This Phase 2 study tests a precise form of radiation therapy to control recurrent ventricular tachycardia (VT), a dangerous fast heart rhythm. It may help people whose VT keeps coming back despite heart medicines and/or ablation, especially when ablation is not possible.
Amsterdam, North HollandAges 18 years+ - 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+ - NCT04844801Recruiting
Prevent fast heart rhythms during sepsis shock with rate control drugs
This trial tests whether a heart-rate–controlling medication can better manage a new fast heart rhythm that happens during sepsis shock. It may help reduce heart strain and improve safety compared with standard care.
ParisAges 18 years+ - NCT04843683Recruiting
Stereotactic radiation treatment for abnormal heart rhythms
This trial studies using a precise type of radiation (stereotactic ablative radiotherapy) to treat abnormal heart rhythms when medicines or prior procedures haven’t worked. It may help by targeting the heart area causing the rhythm problem without doing another invasive ablation.
Toronto, OntarioAges 18 years+ - NCT04750798Recruiting
Monitoring approved catheter devices during heart rhythm ablation
This study is observing people with common abnormal heart rhythms who are already scheduled for a catheter ablation using an approved Biosense Webster catheter. It aims to better understand real-world use and outcomes, without testing a new drug.
GrazAges Any age - 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+ - NCT03047161Recruiting
Fetal heartbeat monitoring in pregnancy
This study looks at how to measure and understand an unborn baby’s heart rhythm using special ultrasound/electrical testing. It may help doctors better evaluate abnormal or possibly abnormal fetal heart rates.
Madison, WisconsinAges 18 years+ - NCT00921986Recruiting
Store heart rhythm samples for arrhythmia research
This study builds a bank of stored heart rhythm-related samples so researchers can study different heart rhythm problems. It may help you or your family contribute to future testing and better care for arrhythmias.
Cleveland, OhioAges 18 years+ - NCT06940752Enrolling by invitation
A new way to treat stubborn heart rhythm problems
This study tests a special navigation technique to improve the success of repeat catheter ablation for ventricular arrhythmias, helping patients who haven't been helped by prior procedures or medications.
Atlanta, GeorgiaAges 21–100 - NCT07137455Enrolling by invitation
New system to record and classify heart electrical signals
This trial is testing a new recording system that helps doctors see and classify the heart's electrical signals during a routine heart procedure. It may improve how doctors treat abnormal heart rhythms or place pacemakers.
Atlanta, GeorgiaAges 21–100 - NCT03821051Recruiting
Registry for heartbeat rhythm problems from structural heart disease
This is a registry that collects information about people with certain dangerous heartbeat rhythm problems caused by structural (anatomical) heart diseases. It may help researchers understand patterns and risks, and improve how these conditions are studied and managed.
Beijing, Beijing MunicipalityAges Any age - NCT03880708Recruiting
Registry for inherited dangerous heart rhythm conditions
This study is a heart rhythm registry for people with inherited conditions that can cause abnormal heart beats. By collecting health and testing information, researchers hope to better understand these conditions and improve care.
Beijing, Beijing MunicipalityAges 1 hour–90 years - NCT04407780Recruiting
Cardio-oncology patient registry
This is a registry (a research database) for people who are being followed in cardio-oncology, which means care for heart problems related to cancer or cancer treatments. It may help doctors better understand these conditions and improve future care.

Registry for people getting a defibrillator implanted in a clinic
This trial is a registry that collects information about outcomes after getting an implantable cardioverter-defibrillator (a device that can help correct dangerous heart rhythms). You may be invited if your doctor recommends the implant to be done at an ambulatory surgical center (a same-day surgery clinic).
Lehi, UtahAges Any age - NCT05617456Recruiting
Test new ablation technology for treating irregular heart rhythm
This study tests advanced technology to improve how atrial fibrillation (AFib) is treated with a heart ablation procedure. It may help patients who are already advised to have AFib ablation by seeing how well the approach works in real clinical practice.
PisaAges Any age - NCT05961865Recruiting
Study of inflammation during catheter ablation for atrial fibrillation
This study measures changes in inflammation in people with atrial fibrillation (AF) who are getting a catheter ablation procedure. It may help doctors better understand what happens in the body during the procedure and why some patients do better than others.

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.
