Dual-chamber pacemaker with specialized heart block pacing
Part of Heart & circulation clinical trials.
This study follows patients who recently received a dual-chamber pacemaker (a device that helps regulate heartbeat) designed to work differently when the heart's electrical signals are delayed or blocked. The trial checks whether this new pacing approach safely reduces irregular heart rhythms and works well over time.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are already enrolled in the BIO|STREAM.CSP registry (a tracking program for this device)
- Your pacemaker was implanted within the last 90 days
- You have sinus node disease (your heart's natural pacemaker isn't working well) plus either a significant delay in electrical signals (PR interval ≥200 ms) or a complete/partial block between upper and lower heart chambers
- Your pacemaker has the DDD-CLS mode turned on (this is the specialized pacing setting)
- You have never had atrial fibrillation (a type of irregular heart rhythm) in your medical history
- Your pacemaker lead uses the new CLS pacing technique, not traditional right-ventricle pacing

Other trials that look related to this one.
This study compares two types of pacemaker pacing methods in people with heart block and normal heart pumping function. It looks at how often short bursts of fast heart rhythm occur in the upper heart chambers, which may help improve long-term heart health.
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.
This study compares two pacemaker pacing strategies—left-sided “bundle branch area” pacing versus right-sided ventricular pacing. It aims to see which approach better prevents heart failure getting worse and reduces abnormal timing between heart chambers over time.
This study tests how a pacemaker affects blood flow and heart health in people with heart block. It aims to see if special pacing settings can improve how the heart works.
This trial compares two pacing methods (LBBAP vs RVP) in people with heart block who need a pacemaker. It looks at whether one method reduces the chance of developing atrial fibrillation (a type of irregular heartbeat). To join, you must have a specific type of heart block, never had atrial fibrillation, and have a healthy pumping heart.
This trial looks at different ways to pace the heart (like left, right, or both sides) to see which works best for people who need a pacemaker. If you have a heart condition requiring a pacemaker, this study may help find the safest and most effective option for you.
