Noninvasive mapping to guide a heart resynchronization device
Part of Heart & circulation clinical trials.
This trial tests a noninvasive way to map your heart’s wiring and veins to help guide placement of a heart resynchronization therapy (CRT) device. If you have certain abnormal heart rhythm and weak heart pumping, it may help doctors place the therapy more accurately and safely.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are age 18 or older and can sign consent
- You have CRT-eligible heart failure with left bundle branch block (LBBB) and a wide QRS (130 ms or more)
- Your heart rhythm is sinus rhythm (not ongoing atrial fibrillation)
- Your left heart pumping is reduced (ejection fraction 35% or less) and you have symptoms despite care (NYHA II or higher)
- You’ve been on stable heart failure medicines for at least 6 months and had no major heart procedure in the last 6 months

This trial tests whether a different pacing approach called left bundle branch pacing can improve outcomes and heart structure changes in people who did not improve with standard biventricular CRT. It may help some patients with ongoing heart failure symptoms and weak heart pumping.
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 study compares different ways of pacing the heart to improve its pumping ability in people with heart failure. It aims to find the best pacing method to help your heart work more efficiently and improve symptoms.
This trial tests a new way to use an ECG (electrical heart recording) to predict who will benefit from a special pacemaker called cardiac resynchronization therapy (CRT). It is for people with heart failure and a specific heart rhythm problem.
This trial tests whether a special noninvasive heart “mapping” test done on the body can help improve outcomes for people who need a CRT device. It studies whether mapping before implantation can better guide or predict how well the CRT will work.
This trial evaluates a noninvasive way to assess who should get Cardiac Resynchronization Therapy (CRT), and to check results after implantation. If you fit the heart rhythm and heart pump criteria, the approach may help confirm whether CRT is appropriate for you.
