Left Bundle Branch Block

Abstract: SUMMARYCoronary angiography, cine left ventriculography, and the cardiovascular hemodynamics of 24 patients with left bundle branch block were studied. Seven

“…These results support that the main cause of LAD in patients with LBBB is anatomical change, such as cardiomegaly or myocardial scarring resulting from previous study. 10) 22) 23) Moreover, lower LVEF seen in the LAD group may be the cause or be a result of LAD. Further physiological or pathological studies are needed to evaluate the mechanism of LAD in LBBB patients.…”

“…The clinical prognostic importance of LAD in LBBB patients has been reported in numerous studies; however, the results remain controversial 1)2)3)4)5)6)14)15). A recent study designed to include subjects without clinical cardiovascular disease reported that LAD was associated with a higher risk of mortality and cardiovascular disease regardless of concomitant LBBB 16).…”

“…Some studies have reported that patients with LAD do not have a significantly different prognosis compared with patients with a normal QRS axis,1)2)3) while others have shown that patients with LAD have a higher incidence of conduction abnormalities and a poor prognosis, including cardiovascular death 4)5)6). Regardless of the differences in prognosis, previous studies have proposed that diseased myocardium is a plausible mechanism for axis deviation 3)4)…”

“…Consequently the depolarization time is doubled, and a reduction in the outflow of both ventricles. The delay in the depolarization of the ventricles is a clinical sign also reflected in the Electrocardiography (ECG) of patients with such condition [153]. The present pathology diminishes the ventricular outflow a ∼ 60% for the LV and ∼ 30% for the RV.…”

“…In this section we induce a pathological condition in the heart model presented in the previous section. First, a left bundle branch block (LBBB) [153,154] is simulated. In this pathology, a faulty conduction system produces dyssynchronous contraction of the ventricles.…”
