肼苯哒嗪广泛用于高血压,其作用为直接扩张高血压病人的外周血管。显著的心功能改变伴随治疗作用的抵销,这就限制了本药的临床应用。本药对心血管的刺激,通常认为系压力感受器—调节反射受血压下降刺激引起。如果这是反应机制所在,心脏刺激的程度应与心血管系统对交感刺激的反应相关,并可能在标准刺激的基础上预测其反应发生。此种预测对选择病例很重要。本文旨在探索上述可能性。
Hydralazine is widely used in hypertension and its role is to directly dilate the peripheral blood vessels of hypertensive patients. Significant changes in cardiac function with the elimination of the role of treatment, which limits the clinical application of the drug. Cardiovascular stimulation of the drug, usually considered Department of baroreceptor - regulatory reflex caused by blood pressure stimulation. If this is the mechanism of response, the extent of cardiac stimulation should be related to the response of the cardiovascular system to sympathetic stimulation and its response may be predicted on the basis of standard stimuli. This prediction is important for the selection of cases. This article aims to explore the above possibilities.
