Answers are grounded in this paper and cite their sources.
Experimental auricular fibrillation significantly reduces blood flow and mixed venous oxygen saturation in dogs, highlighting the hemodynamic compromise caused by the arrhythmia.
The frequent.occurrence of tachycardia, both regular and irregular, in patients makes it desirable to have exact information as to the effect of these rhythms on the circulation. Up to the present few studies have been directed toward this end either in patients or in experimental aninals, because of the difficulty in the first place of obtaining samples of mixed venous blood and in the second place of inducing these rhythms under conditions which were not too far removed from normal conditions.
