A circulatory phenomenon observed in angioma racemosum of the extremities. Compression of an arteriovenous fistula causes a slowing of the heart rate – bradycardia – if there is a significant circulation through the fistula.
The phenomenon was first described by Nicoladoni in 1875, then by Israel in 1877 and Branham in 1890, and subsequently rediscovered by Wigdorowitsch in 1915.
