Coronary hemodynamics in simulated paroxysms of ventricular tachycardia: role of myocardial impairment and of extravascular resistance.

abstract：:The effects of arterial compliance on stenotic hemodynamics were examined in an in vitro arterial preparation. Carotid arteries, obtained from anesthetized mongrel dogs (11.3-15.4 kg), were attached to a perfusion apparatus consisting of a constant pressure reservoir and a fixed distal resistance. To create an intralu...
