Left Bundle Branch Block

Left and right bundle branch blocks are associated with increased rates of pacemaker implantation after undergoing transcatheter aortic valve replacement, with right bundle branch being a much stronger predictor, data show.

Early echocardiography for suspected acute MI in the presence of left bundle branch block may not increase diagnostic accuracy in differentiating chest pain from other causes in hemodynamically stable patients, researchers reported.

Researchers in Spain reported they validated the diagnostic accuracy of the BARCELONA algorithm for acute MI among patients with suspected MI and left bundle branch block who were referred for primary PCI.
