Study of Ventricular Response in Atrial Fibrillation
A study was made of the variation in R-R interval in 47 long electrocardiographic recordings from 17 patients with atrial fibrillation. The distribution curve of ventricular intervals was found to vary in configuration according to the mean ventricular rate. A single high peak was seen at fast rates, two peaks at intermediate rates, and a single low peak flattening to a long low curve at slow rates.
