He found such a condition present In seventy- one out of 300 patients examined, and he believes that if every decompensating heart with arrhythmia was graphically examined, this condition would be frequently found. The alternation may be constant, or it may occur in phases.
A frequent cause of irregular heart action in women, more especially of increased rapidity, is hyperthyroidism. There may be an arrhythmia due to some nervous stimulation, probably through the pneumogastric, so that the pulse varies abnormally during respiration, being accelerated during inspiration and retarded during expiration more than is normally found in adults.
Extrasystoles causing arrhythmia give a more or less regularly intermittent pulse, while the examination of the heart discloses an imperfect beat or the extrasystole which is not transmitted or acted on by the ventricles, and hence the intermittency in the peripheral arteries. This condition may be due to some toxemia, nervous irritability, or some irritation in the heart muscle.

Palpating the radial artery is not absolutely reliable in all cases of auricular fibrillation, or in another form of arrhythmia called auricular flutter or tachysystole. Jour. Med. There is always a certain amount of heart block associated with auricular fibrillation so that not all of the auricular stimuli pass through the bundle of His.
In this kind of arrhythmia, if there are no contraindications to digitalis, it is the logical drug to use from its physiologic activities, slowing the heart by its action on the vagi and causing a steadier contraction of the heart; clinically this treatment is generally successful.
