WebDec 30, 2009 · We have previously 5 demonstrated in a novel rabbit model of myocardial infarction and chronic epicardial pacing that unlike right ventricular (RV) pacing or no pacing, BIV pacing reduces both LV end-systolic and end-diastolic volumes, increases the LV fractional area shortening, and restore the ether-a-gogo myocardial protein levels to … WebLV-only pacing was associated with a lower passing rate (46%) (p < 0.001 versus BIV). The LBBB QRS morphology during inhibited ventricular pacing was acceptable in 51% of patients. The QRS generated by RV pacing was acceptable in 25% of patients. In patients who passed the screening test during BIV, the QRS was not acceptable in 76% during … chin aik hardware trading
