An echographic study was carried out on 17 patients before and after conversion of atrial fibrillation to normal rhythm. It showed up the moment of return of atrial contraction as a movement of the posterior wall of the left auricle and a reappearance of the 'a' wave or the anterior cusp of the mitral valve. The contraction can appear immediately after the electric shock, or may be delayed.
对17例房颤转为正常心律前后的患者进行了超声心动图研究。研究显示,心房收缩恢复的时刻表现为左心耳后壁的运动以及二尖瓣前叶“a”波的再次出现。收缩可能在电击后立即出现,也可能延迟出现。
