The changes in hemodynamics in conditions of dosed loading prior to and post cardioversion were followed up in 21 patients with valvular defects or atherosclerotic myocardiosclerosis and absolute arrhythmia with auricular fibrillation. In conditions of auricular fibrillation all the patients showed data about a deteriorated ventricular function (increased arterial-venous difference--tachycardia), both at rest and at dosed loading. One week after the sinus rhythm restoration, a considerable improvement of ventricular function was observed, at rest and loading (normal arterial-venous difference, higner minute and beat volume), suggesting the favourable effect of the restored sinus activity. The improved ventricular function is due to the restored auricular contraction, together with the restoration of rhythmic cardiac activity.
对21例瓣膜缺损或动脉粥样硬化性心肌硬化并伴有房颤的绝对心律失常患者，在心脏复律前后进行了定量负荷状态下血流动力学变化的随访。在房颤状态下，所有患者在静息和定量负荷时均显示心室功能恶化的数据（动静脉压差增加——心动过速）。窦性心律恢复一周后，观察到静息和负荷时心室功能有显著改善（动静脉压差正常，每分输出量和搏出量增加），提示恢复窦性活动有良好效果。心室功能的改善归因于心房收缩的恢复以及心脏节律性活动的恢复。
