Recruiting studies
- 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+ - NCT06402617Recruiting
Ablation of active spots in atrial fibrillation
This trial is testing a new way to treat atrial fibrillation by using a catheter to target the specific areas in the heart that trigger the irregular heartbeat. If you have persistent atrial fibrillation and haven't had prior catheter ablation, you may be eligible to join.
LondonAges 18–85 - 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 - NCT07621055Recruiting
AI software to guide heart rhythm ablation treatment
This study tests new AI software (Volta AF-Xplorer II) that helps doctors guide catheter ablation—a procedure to treat irregular heartbeats like atrial fibrillation. The software may help doctors perform the procedure more effectively and safely in real-world settings.
MarseilleAges 18 years+ - NCT05288894Recruiting
Italian registry for people with repaired Tetralogy of Fallot
This trial is a registry that collects information about people who have had Tetralogy of Fallot (TOF) repaired. It may help doctors better understand long-term outcomes and improve future care.
Ancona, The MarchesAges 10 years+ - NCT05890716Recruiting
AI analyzes your ECG to help in high-risk heart rhythm cases
This trial uses an AI program to review ECG heart-tracing data collected from short-term monitoring devices. It aims to see whether the AI can better detect concerning heart rhythm patterns in people who are high risk for heart rhythm or heart problems.
Groningen, Provincie GroningenAges 4 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+ - NCT06490432Recruiting
Heart Rhythm Study in Fatty Liver Patients
This study is looking at whether people with a common fatty liver condition (MASLD) have abnormal heart rhythms. If you have MASLD and are 18 or older, you may join to help doctors see if your liver affects your heart's electrical activity.
Sohag, SoAges 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+ - 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 - NCT06763549Enrolling by invitation
AI-powered wearable patch for heart and lung monitoring
This study tests an AI-powered wearable patch (the COR ECG) to see if it can better track heart and lung health. It may help doctors find problems earlier without needing bulky equipment.
Melbourne, FloridaAges 18 years+ - NCT07436962Recruiting
Loop recorder for mitral valve heart condition
This trial tests whether a small heart monitor (loop recorder) can help people with a specific mitral valve condition called mitral annular disjunction. It's for patients who have scar tissue in their heart muscle shown on an MRI.
BudapestAges 18–60 - 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+ - NCT07018596Recruiting
New pulsed field ablation for paroxysmal atrial fibrillation
This trial tests a new type of heart procedure that uses gentle electrical pulses to fix abnormal signals in the upper chambers of the heart for people with a specific type of atrial fibrillation that comes and goes on its own. It may be an option if your AFib episodes stop within 7 days and medications haven't helped enough.
Prague, RoentgenovaAges 18–85 - 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 - NCT04437914Recruiting
Tests a smartwatch to spot heart rhythm and wiring problems
This study checks how accurately a smartwatch can detect heart rhythm and electrical “wiring” problems compared with a standard heart test. If it works well, it could help make heart monitoring easier and more accessible.
Teresina, PiauíAges 18 years+ - 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 - NCT05452356Recruiting
Testing a phone-based care plan for people with heart conditions
This trial tests a phone app that helps deliver organized “care plans” for people with cardiovascular (heart/vessel) conditions. You might join to see if this phone-based support improves how care is delivered and helps you manage your condition.
London, OntarioAges 18 years+ - NCT07727057Recruiting
New catheter treatment for dangerous heart rhythm problems
This study tests a new catheter-based treatment for people with certain types of very fast or extra heartbeats that come from the lower chambers of the heart. The catheter uses a special energy to stop the abnormal beats and might help if you have had symptoms despite other treatments.
GrazAges 18 years+ - NCT06667258Recruiting
Earpiece to detect heart rhythm problems
This trial tests if a special earpiece can detect heart rhythm problems like irregular heartbeats. It could help you monitor your heart in a simple way.
London, Non-US/Non-CanadianAges 18 years+ - NCT02413450Enrolling by invitation
Using patient DNA cells to study inherited heart rhythm risks
This study uses your blood or genetic information to make “iPS cells,” lab-grown cells that can help researchers study inherited heart rhythm problems like LQTS, Brugada syndrome, CPVT, or early repolarization syndrome. It may help improve understanding of why these rhythms happen and guide future treatments.
Baltimore, MarylandAges 18–85 - NCT06804499Recruiting
Coronary artery disease and sudden cardiac arrest study
This study is for people with coronary artery disease (blocked arteries in the heart) who live in the Pirkanmaa area of Finland. It will collect information and blood samples to better understand heart disease and sudden cardiac arrest.
