WebWhile no potentials are seen in the LBBAP lead during LBBB, a sharp potential 20 ms pre-QRS is seen (arrow) when conduction occurs via the left bundle, resulting in a narrow complex. WebStudies using activation mapping have shown that LBBB induced by RVP may worsen conduction barriers in the left ventricle compared with baseline LBBB . Along with the pacing burden, the duration of the paced QRS complex is considered a major predictor of pacing-induced cardiomyopathy, with a directly proportional relationship between the …
