The Archives Of Internal Medicine Vol 1 PDF Download

Excerpt from The Archives of Internal Medicine, Vol. 1: January 15, 1908 This refractory period may be shortened, as is the case in paroxysmal tachycardia, or it may be of longer duration when' the irritability of the heart muscle is impaired by pathologic processes. Every part of the heart is irritable, and every part answers to the normal stimulus with its own rhythm, but the irritability is developed in the highest degree in the venous part of the right auriele, and this most easily excitable part, whose own pulsations are more frequent than those of the ventricles, takes the lead of the other parts and determines the rate of their pulsations. So the venous part of the auriele forces its rhythm on the other parts of the auricles and on the ventricles with which it is connected.
