目的 探讨经皮冠状动脉介入治疗（PCI）对冠心病患者缺血性J波的作用及临床价值.方法 选择山西省心血管病医院经冠状动脉造影确诊并行PCI治疗的冠心病患者117例,记录其PCI术前、术后24 h内的12导联心电图,分别记录五个导联组（分别为Ⅱ、Ⅲ、aVF组,V1、V2组,V3、V4组,V5、V6组及Ⅰ、aVL组）的J波并计算出每例患者发生J波的导联组数（0～5组）.根据时程或波幅将J波分为三个等级：小J波（时程为0.02～0.03 s或波幅0.05～0.09 mV）、大J波（时程＞0.04～0.06 s或波幅＞0.10～0.20mV）和巨大J波（时程＞0.06 s或波幅＞0.20 mV）.分析PCI治疗前、术后冠心病患者发生缺血性J波的导联组数及J波等级的变化.结果 PCI术前、术后患者发生J波的导联组数差异无统计学意义（χ2=6.23,P=0.285、P＞0.05）.PCI术前小J波、大J波和巨大J波分别为157、36、9个,PCI术后三者分别为163、20、5个,小J波所占比例有所增加（77.72%与86.70%）,而大J波和巨大J波所占比例有所下降（17.82%、4.46%与10.64%、2.66%）.PCI治疗前后J波等级比例变化差异有统计学意（χ2=5.28,P=0.022、P＜0.05＝.结论 冠心病的患者PCI术前、术后发生缺血性J波的导联组数差异无统计学意义 但经PCI治疗后,其缺血性J波的发生等级降低,说明PCI对冠心病缺血性J波有较好的影响.
Objective To observe the incidence of ischemic J wave before and post percutaneous coronary intervention （PCI） in patients with coronary heart disease （CHD）. Methods CHD patients （ n =117 ） underwent percutaneous coronary intervention （PCI） in Shanxi cardiovascular hospital were included in this study. The 12-lead ECC s were recorded within 24 hours before and after PCI. The ischemic J waves of five lead-groups （ Ⅱ, Ⅲ ,aVF group： V1, V2 group V3, V4 group V5, V6 group Ⅰ ,aVL group） were analyzed and the number of lead-groups with J waves （ 0 - 5 ） were obtained in each patient. According to time course or wave amplitude, J waves were classified into three grades： small （time course between 0.02 -0.03 s or wave amplitude between 0.05 -0.09 mV）, large （ time course between 0.04 -0.06 s or wave amplitude between 0.10 -0.20 mV） and enormous （time course 〉0.06 s or wave amplitude 〉0.20 mV） J waves. Results The number of lead-groups with ischemic J waves （0 -5 ） in each patient was similar between pre and post PCI in the 117 patients （χ2 =6.23,P=0.285）. The numbers of small, large and enormous J waves were 157, 36 and 9 respectively before PCI and 163, 20 and 5 after PCI. The incidence of small J waves increased （77.72% vs. 86.70% ） while large and enormous J waves decreased （ 17.82%, 4.46% vs. 10.64%, 2.66% ） post PCI （ χ2 = 5.28, P 〈 0.05 ）. Conclusions The numbers of lead-groups with ischemic J waves were similar before and post PCI. However, the amplitude of ischemic J waves decreased after PCI suggesting PCI could improve ischemic J waves in CHD patients.
