In this work the authors propose the Valsalva maneuver as a diagnostic test in a group of patients shown, by anamnestic, physical, and instrumental criteria, to be affected by vasodepressor syncope. They studied the response of heart rate and baseline arterial pressure to the maneuver performed in passive orthostasis in 7 healthy volunteers and 24 patients. These patients showed a hypotensive response and a time of recovery to the initial values that was significantly longer than in the control group (p less than 0.01). The authors conclude that studying the response to the Valsalva maneuver can be useful in the diagnosis of vasodepressor syncope.
在这项研究中，作者提出将瓦尔萨尔瓦动作作为一种诊断测试，应用于一组经问诊、体格检查和器械检查标准显示患有血管减压性晕厥的患者。他们研究了7名健康志愿者和24名患者在被动直立位时进行该动作后心率和基础动脉压的反应。这些患者表现出血压降低反应，且恢复到初始值的时间明显长于对照组（p<0.01）。作者得出结论，研究对瓦尔萨尔瓦动作的反应有助于血管减压性晕厥的诊断。
