This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study compares two different types of upgraded pacing devices for people whose hearts have weakened because of long-term right ventricular pacing. Some patients will receive a newer type of pacing lead that works with your heart's natural electrical system, while others will receive the traditional upgrade approach with three leads. Both treatments are designed to improve how well your heart pumps.
When a pacing device has been delivering most of your heartbeats to the right side of your heart for many years, it can actually weaken your heart function and lead to heart failure. This trial wants to find out if a newer pacing approach works just as well as — or better than — the standard upgrade method for patients in this situation.

You will be randomly assigned to receive one of two types of upgraded pacing devices. Your doctor will place either a newer lead that works with your heart's natural electrical pathways, or the traditional three-lead upgrade system. You will have an ultrasound of your heart at the start and again 6 months after the procedure to measure how much your heart function has improved.
