Complete Right Bundle Branch Block (CRBBB) with Three Different Mean Frontal Plane QRS Axes — A Case ReportDepartment of Internal Medicine, Tokai University School of Medicine, Bohseidai, Isehara, Japan A routine ECG of a seventy-year-old man, who had been followed for five years because of complete right bundle branch block (CRBBB) with first-degree atrioventricular (AV) block, showed CRBBB and three different mean frontal plane QRS axes suggesting normal conduction, bradycardia-dependent left anterior hemiblock, and tachycardia-dependent left posterior hemiblock—all within the same tracing. Holter recording demonstrated transient advanced AV block, and a permanent pacemaker was implanted.
