Besançon, FranceAges 18 years+ - NCT05367037Recruiting
Heart pacing strategy to help prevent ongoing atrial fibrillation
This trial compares two heart pacing approaches to see which one better helps prevent atrial fibrillation (an abnormal heart rhythm). It is for people who need a pacemaker and have a prolonged delay between the upper and lower heart chambers.
Rovigo, VenetoAges 18 years+ - NCT07057544Recruiting
New ECG method to predict CRT benefit in heart failure
This trial tests a new way to use an ECG (electrical heart recording) to predict who will benefit from a special pacemaker called cardiac resynchronization therapy (CRT). It is for people with heart failure and a specific heart rhythm problem.
Prague, Česká RepublikaAges 18 years+ - 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+ - NCT06699342Recruiting
Pacing and heart ablation for atrial fibrillation
This trial tests a combination of heart pacing and a specialized ablation procedure in older adults with permanent atrial fibrillation that hasn't improved with other treatments. It aims to improve symptoms and reduce hospital stays related to heart failure.
Seoul, Jongno-guAges 65 years+ - NCT06299514Recruiting
Pacemaker and ablation for heart failure with atrial fibrillation
This trial tests if a pacemaker plus an ablation procedure can improve heart failure symptoms in people with atrial fibrillation. It is for those with moderate to severe heart failure who are already on the right medications.
Victoria, British ColumbiaAges 18 years+ - NCT06152406Recruiting
Ablate and Pace HIS for atrial fibrillation and heart failure
This study tests a new approach called 'Ablate and Pace HIS' for people with atrial fibrillation and heart failure who haven't improved with other treatments. It combines a heart ablation procedure with a special type of pacing to help your heart pump more efficiently and reduce symptoms.
Leicester, LeicestershireAges 18–100 - NCT06061978Recruiting
Pacing after a heart procedure for rapid atrial fibrillation
This trial studies whether a special type of pacing (stimulating the heart's natural electrical system) works better than standard pacing after a procedure to control very fast heart rhythms. It's for people who already have a pacemaker and are getting a specific treatment for atrial fibrillation.
CaenAges 18 years+ - NCT05265520Recruiting
Pacing strategy study for certain heart failure patients
This trial tests a pacing approach designed to improve how the heart beats in some people with heart failure and a specific heart rhythm pattern on ECG. If you already need a device (CRT-D) based on your results, the study may help see whether this pacing correction improves outcomes.
Phoenix, ArizonaAges 18 years+ - NCT04194632Recruiting
Right heart pacing study for pulmonary hypertension
This study tests whether a temporary pacemaker placed in the right heart chamber can improve heart function in people with pulmonary arterial hypertension. It aims to see if pacing can help the right heart pump more efficiently, potentially reducing symptoms.
San Francisco, CaliforniaAges 18–75 - NCT05236972RecruitingPhase 3
PD-1 antibody after colon cancer surgery for dMMR stage III
This phase 3 trial studies a PD-1 antibody medicine given after surgery to help prevent stage III colon cancer from coming back. It is specifically for people whose tumor is mismatch repair–defective (dMMR) or MSI-H, which may make the cancer more responsive to immune-based treatment.
GuangzhouAges 18–75 - NCT04931550Recruiting
Pacemaker site study to see which placement is best
This study looks at whether placing a pacemaker in different locations affects how patients do afterward. If you recently had a pacemaker implanted and can follow study instructions, you may be able to help researchers compare outcomes.
Hangzhou, ZhejiangAges 18–100 - NCT05896592Recruiting
Ablation versus changing pacing settings for slow heartbeats
This study compares a procedure called cardioneuroablation with staying on permanent pacing in people who have symptoms from a slow heart rate. It aims to see which approach works better and is safer for reducing symptoms related to sinus node or heart conduction problems.
Radom, Masovian VoivodeshipAges 18–65 - NCT07854223Recruiting
