直立倾斜试验诊断分析系统的研制

Method Blood pressure, ECG, cerebral oxygen saturation and sphygmogram of 16 subjects were studied during 75 ° head up tilt plus lower body negative pressure ( HUP+ LBNP).

方法观察16名被试者在75°头高位倾斜加-4kPa下体负压20min期间血压、脉图、心律变异和脑血氧饱和度的变化。

At present, head up tilt test is the gold standard for the diagnosis of VVS.
