Electrocardiographic diagnosis of the left ventricular hypertrophy in patients with left bundle branch block: is it necessary to verify old criteria?

Background: The diagnosis of left ventricular hypertrophy (LVH) in the presence of the left bundle branch block (LBBB) is difficult. In our study we compared commonly used ECG criteria with left ventricular mass index (LVMI) calculated during cardiac magnetic resonance imaging (CMRI) to verify their clinical value or the need to recalibrate.

Methods: CMRI and ECG data of 36 patients were included in this study.
