ATRIOVENTRICULAR BLOCK

This study tests two ways to treat a slow heart rate caused by overactive nerves, without using a permanent pacemaker. One method uses freezing (cryoablation) and the other uses burning (radiofrequency) to calm the nerves. Sixty adults aged 18 to 60 with symptoms like fainting or…

This study is testing a pacemaker lead placed in a specific area of the heart called the left bundle branch area. The goal is to see if this placement is safe and helps the heart beat more naturally in people with slow heart rates. About 140 participants will get the lead and be …

This study tests a newer pacing method called Conduction System Pacing (CSP) against standard right ventricular pacing in 1,260 adults with heart block. The goal is to see if CSP reduces heart failure events, hospitalizations, and need for additional procedures, while also improv…

This study tests a newer pacing method called left bundle branch area pacing against standard pacing in people who need a pacemaker after a TAVI procedure. About 266 participants will be enrolled to see if the new method reduces heart-related deaths, hospitalizations for heart fa…

This study compares two ways of placing a pacemaker lead in people who need frequent pacing. One method (left bundle branch pacing) aims to activate the heart more naturally than the standard method. The goal is to see if it reduces the time the heart spends in fast, irregular rh…

This study compares a newer pacemaker method, left bundle branch area pacing (LBBAP), to the standard right ventricular pacing in 200 patients with heart block and normal heart function. The goal is to see if LBBAP better preserves the heart's pumping ability and reduces complica…

This study compares two ways to place a pacemaker in people with heart block (a condition where the heart's electrical signals slow or stop). One method uses standard right ventricular pacing, the other uses conduction system pacing (targeting the heart's natural electrical pathw…

This study tests if a newer pacing method, left bundle branch area pacing, is better than standard right ventricular pacing for people who need a pacemaker. Researchers will compare outcomes like death, heart failure, and heart damage in 450 participants over two years. The goal …

This study tests whether wearing a portable ECG monitor for 30 days after a heart valve replacement (TAVI) can detect dangerous heart rhythm problems better than the usual 1-2 days of hospital monitoring. 250 patients will be randomly assigned to either the extended monitoring gr…

This study tests whether a newer pacemaker method (conduction system pacing) can better prevent heart muscle weakening compared to the standard method. Researchers will enroll 200 adults who need a pacemaker for a slow heart rhythm. The goal is to see which approach reduces the r…

This study is observing 150 people who have a pacemaker with a special setting called Closed Loop Stimulation (CLS) combined with left bundle branch area pacing. The goal is to see if this setting reduces the occurrence of atrial fibrillation over two years. Participants have sin…

This study looks at how a special pacing method called His bundle pacing affects the heart's electrical activity in 80 people with bradycardia (slow heart rate) or heart failure. Researchers will take extra measurements during standard pacemaker implantation to see if this techni…
