Read our Heart Failure research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing two different approaches to pacing your heart if you have atrial fibrillation (an irregular heartbeat) and a weakened heart pump. One approach uses left bundle branch area pacing, and the other uses biventricular pacing — both are designed to help your heart beat more efficiently and prevent further damage.
When patients have an irregular heartbeat and a weakened heart, they often need a pacemaker to help control their heart rhythm. However, traditional pacing can sometimes make the heart weaker over time. This trial exists to find out which of these two newer pacing methods works best at preventing that damage and helping patients feel better.

If you join this study, you will receive a pacemaker with one of the two pacing strategies. You'll use that strategy for 6 months, then switch to the other strategy for another 6 months. During this year, you'll have regular clinic visits, heart tests (like ECGs and ultrasounds), and assessments of how you're feeling and how far you can walk. After the first year ends, you'll be followed for 2 more years with additional check-ups to see how well the pacing is working long-term.
