our findings indicate that 1 ) differential reflex changes in cardiac sympathetic activities during 30 min of left ventricular ischemia are due to afferent signals originating from the ischemic region , 2 ) both sympathetic and vagal afferent fibers participate in the ischemia-induced cardio-cardiac reflex , and 3 ) the nature of the sympathetic reflex response to acute ischemia is influenced by a previous ischemic insult .
