In patients with coronary artery disease, vagal dominant impairment in autonomic cardiac function and that reduction in the vagal cardiac function correlates with the angiographic severity. In the case of cardiomyopathy, a decrease in parasympathetic and an increase in sympathetic tone are reported. It has been proposed that head-up tilt test (HUT), either alone or in conjunction with isoproterenol infusion (ISP) may be useful in evaluating neurally mediated syncope. To elucidate the etiology of unexplained syncope, 15 patients were studied. In 10 patients (67%), neurally mediated bradycardia/hypotension were inducible by HUT in conjunction with ISP.}, pages = {16--21}, title = {3)循環器疾患における自律神経障害の診断(シンポジウム 自律神経障害の診断と治療 : その新しい展開, 第500回新潟医学会)}, volume = {109}, year = {1995} }
