title = "The effect of phentolamine on intra-hisian conduction",
abstract = "A His bundle electrogram was obtained in a 70 year old male with syncopal episodes. A split bundle of His deflection was recorded. After the intravenous administration of phentolamine, a marked shortening of the H-H' interval was observed. This signifies an improvement in conduction at the bundle of His level.",

note = "Funding Information: Phentolamine can increase the availability of endogenous catecholamines to the heart. This contention is supported by the work of Diarman and co-workers. 7 They administered phentolamine 5 mg/kg to rats. At the height of receptor blockade, the conversion of a tracer dose of tyrosine14c to norepinephrine was increased threefold, with no alteration in specific activity of tyrosine in blood and tissues. From these studies Dairman and his co-workers concluded that receptor blockade led to increased synthesis and release of norepinephrine in the three organs that were measured.
