Although internal cardioversion (IC) for atrial fibrillation (AF) is effective at restoring sinus rhythm, immediate recurrence (IR) of AF after IC is a major and largely unpredictable clinical problem. The purpose of the study was to determine the role of P wave duration and amplitude in prediction of IR of AF after IC. Forty-five consecutive patients undergoing IC for chronic AF were evaluated.
After successful IC, 1-minute ECG recording was obtained in all patients. P wave duration and amplitude in Lead II and V1 were measured using computer. Forty patients (88%) had successful IC. Thirteen patients experienced IR of AF within 1 minute of restoring sinus rhythm.
As a result, the incidence of IR of AF after IC was higher in the patients with shorter P wave amplitude (for lead II P<0.01, for V1 P<0.01) and larger P wave duration (for lead II P<0.01, for V1 P<0.05).
虽然心房颤动（AF）的体内心脏复律（IC）在恢复窦性心律方面有效，但IC后房颤的即刻复发（IR）是一个主要的且很大程度上不可预测的临床问题。本研究的目的是确定P波持续时间和振幅在预测IC后房颤IR中的作用。对45例连续接受慢性房颤IC治疗的患者进行了评估。
IC成功后，所有患者均进行了1分钟的心电图记录。使用计算机测量II导联和V1导联的P波持续时间和振幅。40例患者（88%）IC成功。13例患者在恢复窦性心律后1分钟内发生房颤IR。
结果显示，IC后房颤IR的发生率在P波振幅较短的患者中较高（II导联P<0.01，V1导联P<0.01），且P波持续时间较长（II导联P<0.01，V1导联P<0.05）。
