In this report, a brief history of the Valsalva (Valsalva-Weber) maneuver is outlined, followed by an explanation on the use of this approach for the evaluation of cardiac autonomic function based on underlying heart rate changes. The most important methodological and interpretative aspects of the Valsalva-Weber maneuver are critically updated, and some guidelines are established for simple application of the maneuver in a teaching or research laboratory setting. These include the hemodynamic and cardiac autonomic mechanisms involved, technical aspects such as the intensity and duration of the expiratory straining, frequency of maneuver sessions, training and posture of the individuals tested, different time- and grade change-dependent indexes of heart interval variation, and clinical application of the maneuver.
在本报告中，概述了瓦尔萨尔瓦（瓦尔萨尔瓦 - 韦伯）动作的简史，随后基于潜在的心率变化对该方法用于评估心脏自主神经功能进行了解释。对瓦尔萨尔瓦 - 韦伯动作最重要的方法学和解释性方面进行了批判性更新，并制定了一些指南，以便在教学或研究实验室环境中简单应用该动作。这些包括所涉及的血流动力学和心脏自主神经机制、诸如呼气用力的强度和持续时间等技术方面、动作测试的频率、受测个体的训练和姿势、心脏间期变化的不同时间和等级变化相关指标，以及该动作的临床应用。
