Clinical analysis of the PJ interval of late diastolic premature ventricular contraction in sinus rhythm

摘要: 目的：探讨窦性心律下舒张晚期室性期前收缩病人经导管射频消融术前后的心电图，并分析不同部位旁路前传对PJ 间期的影响。方法：选择经动态心电图窦性心律下确诊为舒张晚期室性期前收缩病人120例。根据旁路部位分为10组，经导管射频消融术前后分别扫描窦性12导联同步心电图，测量PR间期、QRS间期、PJ间期及δ波时间。结果：与术前比较，120例窦性心律下舒张晚期的室性期前收缩病人中，LPS、RA、RP、RAS、RMS和RPS组病人术后PJ间期均显著延长（P<0.01），而其他部位旁路的病人术后PJ间期变化差异均无统计学意义（P>0.05）。心电图结果显示，术后LL、LPS、RA、RP组PR间期均较术前延长（P<0.05~P<0.01），其他各组术后PR间期变化差异均无统计学意义（P>0.05）。术后LPS、RL、RP、RAS、RMS和RPS组病人QRS时间长于术前（P<0.05~P<0.01），其他部位旁路术后QRS时间变化差异均无统计学意义（P>0.05）。术前各组的δ波时间差异均无统计学意义（P>0.05）。结论：窦性心律下舒张晚期室性期前收缩病人心电图PJ间期缩短在与间歇性预激综合征鉴别时具有重要的临床价值，值得推广到基层医院，利于窦性心律下舒张晚期室性期前收缩病人的心电图诊断和鉴别。

Abstract: Objective:To investigate the electrocardiogram(ECG) of patients with late diastolic premature ventricular contraction in sinus rhythm before and after radiofrequency catheter ablation,and analyze the effects of different bypass prequels on the PJ intervals.Methods:A total of 120 cases with late diastolic premature ventricular contraction in sinus rhythm diagnosed by dynamic electrocardiogram were divided into 10 groups according to the bypass.Twelve lead synchronous ECG were scanned before and after radiofrequency catheter ablation,and the PR interval,PJ interval,QRS interval and δ wave time were measured.Results:Compared with before operation,the postoperative PJ intervals in LPS,RA,RP,RAS,RMS and RPS group significantly prolonged(P< 0.05),and the differences of the postoperative PJ intervals between other groups were not statistically significant(P>0.05).The ECG results showed that the postoperative PR intervals in LL,LPS,RA and RP group significantly prolonged compared with before operation(P< 0.05 to P<0.01),and the differences of the postoperative PR intervals between other groups were not statistically significant(P>0.05).The postoperative QRS intervals in LPS,RL,RP,RAS,RMS and RPS groups were longer than those before operation(P<0.05 to P<0.01),and the differences of the postoperative GRS intervals between other groups were not statistically significant(P>0.05).The differences of the δ wave times in all groups before operation were not statistically significant(P>0.05).Conclusions:The PJ interval shortening of ECG has important clinical value between contraction in sinus rhythm and intermittent preexcitation syndrome,which is worthy of promotion in primary hospital,and helpful for the ECG diagnosis and differential diagnosis of late diastolic ventricular premature contraction in sinus rhythm.
