Bradycardia

This trial tests two ways of placing a pacemaker lead in the heart's left bundle branch area. One strategy aims to directly capture the heart's conduction system, while the other accepts capture of the nearby septal muscle. Researchers will compare how well the heart's pumping fu…

This trial tests whether a small leadless pacemaker, the Aveir VR, can be safely implanted through the jugular vein in the neck instead of the usual route. Researchers will enroll 15 adults with slow heart rhythms who need ventricular pacing. The main goal is to see if the proced…

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…

Researchers at Assiut University Children Hospital are studying how often children who come to the emergency department have an abnormal heart rhythm. The study includes children aged 1 month to 18 years who arrive with symptoms such as palpitations, chest pain, fainting, or trou…

This study will test a new pacing lead called LINEA, designed to be placed in the wall between the heart's lower chambers. Researchers want to see if it is safe and works well in 450 people who need a pacemaker. The main goals are to check for complications and measure how well t…

This study tests a small, sticky patch that records heart rhythms in hospitalized patients who need continuous monitoring. The patch sends data to a central system for real-time alerts and later review. Researchers want to see if it helps doctors make faster decisions about treat…
