摘要

目的 探讨心电图P波形态、电压及时间(MVP)积分在阵发性心房颤动(下称房颤)射频导管消融术(下称消融)后随访中的临床价值.方法 选择2018年2月至2022年1月嘉兴市第一医院(嘉兴大学附属医院)收治的心房颤动消融患者84例,随访1年,依据房颤是否复发分为未复发组60例、复发组24例.比较两组患者消融前、消融后1年心电图P波参数(MVP)积分、超声心动图检查指标.结果 未复发组消融前患者P波时间、MVP积分小于复发组,P波面积大于复发组,未复发组消融后1年患者P波时间、V1P波负向部分振幅和时间的乘积(PtfV1)、P波面积、MVP积分小于复发组,差异均有统计学意义(均P＜0.05).复发组消融后1年PtfV1 大于消融前,差异有统计学意义(P＜0.05).心电图P波时间、P波面积、MVP积分是房颤消融后房颤复发的影响因素(均 P＜0.05).ROC曲线分析发现,MVP积分诊断房颤复发的AUC较大(P=0.001).未复发组消融前后左心房前后径(LAD)小于复发组,消融后左心室短轴缩短率、左心室射血分数大于复发组,差异均有统计学意义(均P＜0.05).复发组消融前后MVP积分与LAD均呈正相关(r=0.312、0.381,均P＜0.05).结论 心电图MVP积分有助于预测房颤消融后复发.

Abstract

Objective To explore clinical significance of electrocardiogram P wave morphology-voltage-P duration(MVP)score in the follow-up of patients after catheter ablation of paroxysmal atrial fibrillation(AF).Methods A total of 84 AF patients underwent radiofrequency catheter ablation in the First Hospital of Jiaxing from February 2018 to January 2022 were included and followed up for 1 year.AF reoccurred in 24 cases(recurrent group)and not in 60 cases(non-recurrent group).P-wave parameters,MVP scores and echocardiography measurements before and 1 year later after ablation were compared between the two groups.Results P-wave duration and MVP score were significantly lower and P-wave area was significantly higher in the non-recurrent group than in the recurrent group before AF ablation(all P＜0.05).P-wave duration,PtfV1,P-wave area,and MVP score were significantly lower in the non-recurrent group than in the recurrent group 1 year later after ablation(all P＜0.05).PtfV1 was significantly higher 1 year later after ablation than before in the recurrent group(P＜0.05).P-wave duration,P-wave area and MVP score were the factors influencing AF recurrence(all P＜0.05).ROC curve analysis showed in the diagnosis of AF recurrence,the AUC of MVP score was higher(P=0.001).Left atrial diameter before and after ablation in the non-recurrent group were significantly lower than that in the recurrent group,while left ventricular fractional shortening and ejection fraction after ablation were significantly higher than those in the recurrent group(all P＜0.05).MVP score was positively related to left atrial diameters pre-and post-ablation in the recurrent group(r=0.312,0.381,both P＜0.05).Conclusion ECG MVP score is helpful in predicting AF recurrence after ablation.
