The first record of this abnormality was described by Wilson1 in 1915, who believed it to be vagal effect. Wedd2 reported another such case in 1921 and called it "A-V nodal rhythm." Hamburger3 in 1924 reported four cases of "intraventricular conduction disturbances with unusual clinical features."
Wolff, Parkinson and White4 were the first to recognize this abnormality as a clinical syndrome. The possibility of an accessory pathway producing this picture was first suggested by Holzmann and Scherf.5
Electrocardiographic tracings have the following characteristic pattern:
a. Short PR interval.
b. Prolonged QRS complex with slurring.
