Narrow QRS complex beat or tachycardia is not diagnostic of supraventricular origin. In particular, narrow QRS complexes can arise from the ventricle in close proximity to the His-Purkinje system that activates right and left ventricular muscle in a balanced manner, or owing to ventricular ectopy occurring ipsilateral to bundle branch block and simultaneous with intrinsic conduction.
