Sinoatrial node disorder

This study tests whether pacing the heart from a specific spot (posterosuperior bundle) can lower the chance of atrial fibrillation (AF) in people with sinus node dysfunction (a slow or irregular heartbeat). About 300 adults who need a pacemaker will be randomly assigned to get p…

This study looks at whether setting a pacemaker to a personalized rate of 75 beats per minute, instead of the usual 50-60, can improve heart function and blood flow to the brain in people with high blood pressure and a slow heart rate. About 70 patients aged 65 and older will be …

This study tests a new, small pacemaker that doesn't need wires (leads) to help people with a slow heartbeat. About 15 adults with certain heart rhythm problems will get the device to see if it's safe and works well. The pacemaker is placed directly in the heart to keep the beat …

This early study tests a new, wire-free pacemaker (ALPS) in 10 people with bradycardia (slow heart rate). The goal is to see if it is safe and works well. Participants will be monitored for device-related problems and how well the pacemaker controls their heart rhythm.

This trial tests two different heart pacing leads—one without a hollow core (lumenless) and one with a stylet—to see which works better for left bundle branch pacing. About 288 people with slow heart rhythms will take part. Doctors will use continuous monitoring to guide the lead…

This study explores whether the electrical signal measured by a pacemaker or defibrillator during implantation can help identify cardiac amyloidosis — a condition where abnormal proteins build up in the heart. Researchers will enroll 242 adults aged 65 and older who already need …

This study aims to see if artificial intelligence can predict serious heart rhythm problems, like atrial fibrillation, after high-risk surgeries. Researchers will record ECGs from 300 adults before surgery and analyze over 200 heart cycle parameters to find the best prediction me…

This study will follow 500 people with dual-chamber pacemakers to see how the pacemaker's programming affects the development of permanent atrial fibrillation (AF), a common heart rhythm problem. Researchers will track AF episodes, quality of life, hospitalizations, and deaths ov…
