摘要

作者研究了Valsalva机动过程中自主心血管的无创控制。为了评估控制的程度，通过基于pc的计算机系统连续监测心率(HR)、t波振幅(TWA)、脉冲传递时间(PTT)和手指脉搏量(FPV)。结果表明，Valsalva手法可以作为一种无创手段来操纵心脏和血管的自主作用，并且该系统可以有效地监测这些作用。

Noninvasive monitoring of autonomic cardiovascular control during stress

The authors examined noninvasively the autonomic cardiovascular control during Valsalva maneuver. In order to assess the extent of the control, heart rate (HR), T-wave amplitude (TWA), pulse transit time (PTT), and finger pulse volume (FPV) were monitored continuously through a PC-based computer system. Results show that Valsalva maneuver can be used as a noninvasive means of manipulating autonomic effects on the heart and blood vessels and that the system is effective for monitoring these effects.<>
