Increased aortic intima-media thickness: a marker of preclinical atherosclerosis in high-risk children.

abstract：:Multiple areas of concealed intraventricular conduction are deduced on the basis of aftereffects observed in His bundle recordings. Electrocardiograms and His bundle recordings are presented from two patients with unstable bilateral bundle branch block, the instability of which depended on the interval at which ventri...
