Imaging after a heart device to optimize pacing settings
Part of Heart & circulation clinical trials.
This study uses a heart MRI (a special scan) to better map the heart’s electrical activity, with the goal of fine-tuning settings on your implanted pacing device. It’s meant to improve how well the device coordinates your heartbeat.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You already have a CRT-D or CRT-P implanted (a pacemaker/defibrillator type for heart rhythm).
- Your specific device must support SyncAV® programming software.
- You need a left bundle branch block diagnosis before the CRT was implanted.
- Before your implant, your PQ interval on your ECG must be 250 milliseconds or less.
- You must be able to safely have a cardiac MRI (for example, no severe claustrophobia).

This study looks at how different pacing methods affect heart function using MRI and advanced ECG imaging. It aims to find the best pacing approach for people with slow heart rhythms who need a pacemaker.
This study tests a new heart scan method to help doctors place pacemakers more accurately for people with heart failure. It aims to improve the effectiveness of the pacemaker treatment and may lead to better outcomes for patients.
This study compares two ways of programming a special pacemaker (CRT-D) to improve heart function in people with heart failure. The goal is to see if the automatic continuous AV delay optimization (Sync-AV) works better than the standard pacing method.
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.
This trial tests whether using detailed heart scans (PET and CT) to guide the placement of a special pacing wire can improve outcomes for people with heart failure who have a specific ECG pattern. If you qualify, you may receive more personalized placement of the pacing lead.
This study tests a new way to guide pacemaker placement using electrical mapping to improve heart pumping in people with heart failure. It may help your heart beat more in sync, which can ease symptoms and improve quality of life.
