Summary

This study tested two different methods of pacing the left side of the heart in people with severe heart failure. The goal was to see if pacing from inside the heart (endocardial) works better than the usual method from outside (epicardial). Only 6 adults took part, and the main focus was on immediate improvements in heart pumping strength.
