The purpose of this study was to investigate the effect of the Valsalva maneuver on P-wave durations and dispersion. After the Valsalva maneuver, we found that maximum P-wave duration increased, minimum P-wave duration decreased, and P-wave dispersion increased in controls, whereas the opposite was true for unselected patients with paroxysmal AF. It was concluded that patients with paroxysmal AF performing the Valsalva maneuver normalized their P-wave dispersion, thereby correcting the inhomogeneous intra-atrial conduction.
本研究的目的是调查瓦尔萨尔瓦动作对P波时限及离散度的影响。在瓦尔萨尔瓦动作后，我们发现对照组中最大P波时限增加，最小P波时限减小，P波离散度增加，而未经选择的阵发性房颤患者情况则相反。得出的结论是，进行瓦尔萨尔瓦动作的阵发性房颤患者其P波离散度恢复正常，从而纠正了心房内传导的不均一性。
