Comparing two types of heart pacing for sick sinus syndrome
This study compares two different ways of placing a pacemaker lead to see which one better helps heart function and reduces future heart problems in people with sick sinus syndrome.
Seoul, SeoulAges 19 years+ - NCT07372196Recruiting
Left bundle branch pacing after myectomy for hypertrophic cardiomyopathy
This trial is testing a new way to pace the heart (left bundle branch pacing) for people with hypertrophic cardiomyopathy who still have a dangerous heart rhythm problem after myectomy surgery. It aims to see if this pacing can reduce the risk of sudden cardiac death.
Novosibirsk, Novosibirsk OblastAges 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+ - NCT07534917Recruiting
New Pacemakers and Heart Function Study
This study compares newer pacemaker types to see how well they work and how they affect your heart's pumping ability and valve function over a short period. You'll be monitored closely with heart imaging to understand which pacemaker performs best.
LondonAges 18 years+ - 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+ - NCT07270536Recruiting
Pacing and heart pressure in HFpEF exercise
This study tests whether a special pacing setting during exercise can help improve heart filling pressures in people with heart failure with preserved ejection fraction (HFpEF) who already have a DDD pacemaker. If you have HFpEF and a pacemaker, you may help researchers find better ways to manage your condition during activity.
HasseltAges 18 years+ - NCT06474819Recruiting
Comparing two pacemaker lead placements to protect heart function
This study compares two ways of placing a pacemaker lead to see if one protects your heart's pumping ability better over time. It may help prevent heart muscle weakness caused by pacing.
BarcelonaAges 18 years+ - NCT07733960Recruiting
Pacing system study for heart pacing therapy
This trial tests a new pacing system designed to improve how pacemakers work. It may help people who need a pacemaker with left bundle branch area pacing.
Madurai, Tamil NaduAges 18 years+ - NCT03957343Recruiting
Parkwood Pacing and Planning app for concussion recovery
This study tests a smartphone or tablet app (the Parkwood Pacing and Planning app) that may help people after a mild concussion manage recovery. You may be able to join if you’re an adult, can use the app device, and have a confirmed mild concussion.
London, OntarioAges 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+ - 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+ - 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 - NCT06189976Recruiting
Can a quick heart pacing test after TAVI predict pacemaker need?
This study checks if a short, controlled heart pacing procedure right after your TAVI (a valve replacement) can tell doctors whether you might need a permanent pacemaker later. It aims to help avoid unnecessary pacemakers.
BrusselsAges 18 years+ - NCT06207383Recruiting
Comparing heart treatments for atrial fibrillation and heart failure
This study compares two treatments for people with atrial fibrillation and heart failure: one is a procedure to fix the irregular heartbeat (AF ablation), and the other involves a different type of pacing for the heart. It aims to find which approach helps you feel better and stay out of the hospital.
GrazAges 60 years+ - NCT06609577Recruiting
Ultrasound-guided diaphragm pacing for patients on ventilators
This trial tests a personalized pacing device that uses ultrasound to help your diaphragm muscle work better while you are on a breathing machine. It may help you breathe on your own sooner and improve your recovery.
Nantong, JiangsuAges 18–95 - NCT06699342Recruiting
