Patients with recurrence of persistent atrial fibrillation within 30 days of cardioversion had slower atrial conduction, a slower sinus rate, no difference in the absolute value of the effective refractory period, greater early reverse remodeling of the effective refractory period, and more premature atrial contractions than those who did not. These findings highlight the role of slow conduction and premature atrial contractions in the pathophysiology of atrial fibrillation and suggest a possible proarrhythmic effect of reverse remodeling.
在心脏复律后30天内出现持续性心房颤动复发的患者，其心房传导较慢、窦性心率较慢、有效不应期绝对值无差异、有效不应期早期逆向重构更明显，且房性早搏比未复发者更多。这些发现突出了缓慢传导和房性早搏在心房颤动病理生理学中的作用，并提示逆向重构可能具有促心律失常作用。
