Why the study?
Does electrically induced atrial and ventricular tachycardia alter cardiac output, coronary blood flow, and mean arterial blood pressure in anesthetized dogs?
Does electrically induced atrial and ventricular tachycardia alter cardiac output, coronary blood flow, and mean arterial blood pressure in anesthetized dogs?
In a canine model, induced tachycardia transiently impairs hemodynamics, with higher rates causing sustained reductions in cardiac output and blood pressure, and ventricular tachycardia exerting more severe effects than atrial tachycardia at equivalent rates.

Tachycardia hemodynamics in canine models inform experimental arrhythmia research; leaves open translation to human physiology and practice.
Wégria et al. (1958) studied this question.
