目的 探讨V1P波终末电势(PtfV1)在缩窄性心包炎与渗出性心包炎鉴别诊断中的价值.方法 回顾性分析53例缩窄性心包炎及64例渗出性心包炎患者的心电图和超声心电图资料,测定PtfV1及校正的QT(QTc)间期,进行组间比较.结果 左心房大小、左心室舒张末期内径和左心室射血分数在缩窄性心包炎与渗出性心包炎两组之间差异无统计学意义(均P＞0.05).缩窄性心包炎组PtfV1增大的比例(64.2％)显著高于渗出性心包炎组(9.4％),差异有统计学意义(P＜0.05).结论 PtfV1有利于缩窄性心包炎与渗出性心包炎的鉴别诊断.%Objective To explore the clinical value of P wave terminal force in lead V1 (PtfV1) in distinguishing constrictive pericarditis from exudative pericarditis. Methods The data of ECG and echocardiography were analyzed retrospectively in 53 patients with constrictive pericarditis and 64 patients with exudative pericarditis. Ptf V1 and corrected QT interval (QTc) were measured and compared between groups. Results left atrial diameter, left ventricle end diastolic diameter and left ventricular ejection fraction were not significantly different between constrictive pericarditis and exudative pericarditis. The incidence of Ptf V1 increase was significantly higher in constrictive pericarditis group (64.2％) than in exudative pericarditis group (9.4％) (P＜0.05). Conclusion Ptf V1 may be benefit to the differential diagnosis between constrictive pericarditis and exudative pericarditis.
