The cardiovascular physiologic effects of traumatic brain injury remain only partially understood. The autoregulatory manifestations of closed head injury have long been considered to be a catecholamine-mediated phenomenon [1]. Tachycardia, hypertension, coronary vasoconstriction resulting in cardiac ischemia, and arrhythmia have been attributed to sympathetic over activity [2]. However, these responses may not be physiologic [3]. Cardiac function is also regulated by baroreceptors, which are… CONTINUE READING
