Clinical finding in AV fistula is one of the following: (A) Pericarditis, (B) Sinus tachycardia, (C) Cardiac arrhythmia, (D) Hypothermia
Answer is B. The mechanism behind bradycardia associated with Branham sign is likely similar to the reflex arc that occurs during the Bezold-Jarisch reflex. Presence of an AV fistula results in increased cardiac output because of low resistance across the AV shunt. Ref Davidson 23rd edition pg 467
