VCG patterns may identify underlying disease in RBBB; hypothesis-generating and requires prospective validation before clinical use.
Can the vectorcardiogram transverse plane QRS configuration predict cardiac failure or severe pulmonary disease in patients with right bundle branch block?
In patients with right bundle branch block, the position of the afferent limb in the transverse plane on vectorcardiogram can help predict the presence of underlying cardiac failure or severe pulmonary disease.
