It may also follow infections such as diphtheria, or some infection which has caused a myocarditis. Rarely this fibrillation may be caused by some of the drugs used to stimulate the heart. It is astonishing how few symptoms may be present with auricular fibrillation and an absolutely irregular heart action.

He also believes that when the heart in auricular fibrillation is increased the normal amount or more than normal, the prognosis is good. He still further advises in auricular fibrillation an injection of atropin before digitalis has been administered, and another after digitalis is thoroughly acting.
Consequently, although a pathologic condition of the node is a frequent, and perhaps the most frequent, cause of auricular fibrillation, other conditions, especially anything which dilates the right auricle, may cause it. If the pulse is intermittent and there is apparently a heart block.
Here was another new fact: that the pulsation in the arteries was nothing else than the impulse of the blood within them. It is interesting to note that he mentions what is probably auricular fibrillation.
The tracing of the carotid and radial shows the activity of the left side of the heart. After normal tracings have been carefully taken and studied by the clinician or a laboratory assistant, abnormalities in these readings are readily shown graphically. Especially characteristic are tracings of auricular fibrillation and those of heart block.
It seems to be probable that more than half of all cases of heart failure are due to auricular fibrillation, or at least are aggravated by it.
The irregular pulse in auricular fibrillation is more or less distinctive, being generally rapid, from 110 upward. Occasionally the pulse rate may be much slower, if the heart is under the influence of digitalis.
Both auricular fibrillation and auricular flutter are best shown by the polygraph and the electrocardiograph. The former is more exact as to details. Auricular flutter, which has also been called auricular tachysystole, is more common that is supposed. It consists of rapid coordinate auricular contractions, varying from 200 to 300 per minute. Int.
This condition is generally termed by the patient a "palpitation," and palpitation of the heart is recognized by most physicians as meaning a too rapidly acting heart, the term "tachycardia" being reserved for an excessive rapidity of the heart. Many of the so- called tachycardias are really instances of auricular fibrillation or flutter.
