Abstract

In this study we establish an animal model of chemotherapy-induced autonomic neuropathy. Rats were injected with vincristine (30 and 100 μg/kg/day) for 2 weeks while cardiovascular parameters were collected telemetrically. Vincristine caused a dose-dependent decrease in vagal activity expressed by decreased parasympathetic parameters of heart rate variability, without expression of damage to the cardiac sympathetic innervation. This model can serve in assessing the potential contribution of chemotherapy-induced vagal neuropathy to morbidity and mortality. Muscle Nerve, 2008
