VT-induced hypotension impairs rat CBF autoregulation more than hypovolemia; leaves open human relevance and etiology-specific mechanisms.
Does the cause of acute hypotension (ventricular tachycardia vs. hemorrhage) affect cerebral blood flow autoregulation in rats?
The autoregulatory ability of the brain is substantially more stable during hypovolemic hypotension than during normovolemic hypotension induced by ventricular tachycardia.
Kastrup et al. (1998) studied this question.
