Global and Regional Myocardial Oxygen Consumption and Blood Flow in Severe Cardiomyopathy with Left Bundle Branch Block

Abstract

DCM patients with LBBB exhibit a more heterogeneous distribution of MVO(2) and MBF among the myocardial walls than DCM patients without LBBB. Due to the LBBB associated electromechanical alterations, the highest regional values of MVO(2) and MBF are found in the lateral wall.
