本文介绍诊断糖尿病心血管植物神经病变的五种简单、客观而可靠的方法。一、反映副交感神经损伤的试验 1、瓦氏呼气动作效应:正常人Valsalva呼气动作时血压下降,心率上升,动作解除后血压回升且超过静息水平,心率亦减慢。在植物神经损伤病人,其血压在呼气时下降缓慢,动作解除后亦回升且不超过静息水平,心率多无变化。方法:病人取坐位,向含在口中的通气管吹气,使连通的气压 This article describes five simple, objective and reliable ways to diagnose diabetic cardiovascular autonomic neuropathy. First, reflect the test of parasympathetic injury 1, Valsalva expiratory action effect: Valsalva normal people when blood pressure drops, heart rate rises, the lifting of the blood pressure after lifting and more than the resting level, heart rate also slowed down. In patients with autonomic nerve injury, blood pressure drops slowly during expiration, after lifting the action also rose and does not exceed the resting level, no change in heart rate. Methods: The patient take a seat, blowing in the mouth of the vent, so that the pressure of communication
