BNP at low and high LVEF groups within mid-septal pacing

Different levels of LVEF appear to be a key factor for the therapy of mid-septal pacing. The lower LVEF (35%<LVEF≤40%) group has a better BNP-decreasing effect than the higher LVEF (40%<LVEF≤50%) group based on the same mid-septal pacing conditions (P<0.05). ^* P>0.05, ^** P<0.05, vs. baseline. Data are expressed as mean±SD
