直接冠脉介入干预对早期急性心肌梗塞患者QTd的影响

Research the Effect of Primary Coronary Intervention on QT dispersion of Patients with Early AMI

目的:对74例早期急性心肌梗塞(AM I)者行直接冠脉介入干预(PCI)治疗前后QTd、QTcd作观察,研究其变化的临床意义。方法:于PCI治疗前后行标准12(或18)导联心电图检查,测量QTd变化。结果:早期AM I者行PCI术前后QTd有非常显著性差异(72.6±30.2)ms与(36.6±16.5)ms,P<0.01;QTd有非常显著性差异(76.3±29.6)ms与(32.8±12.2)ms,P<0.01。结论:直接PCI成功可明显降低QTd、QTcd,减少严重室性心律失常和猝死的发生。

Objective： 74 cases with early AMI were adopted primary coronary intervention （PCI）, to study the clinical significance of the changes of QTd and QTcd before and after treatment. Method： They were detected the standard lead of 12 （ or 18 ） ECG and then observed the changes of QTd before and after treatment of PCI. Result： There＇s significant difference （ 72.6 ＋ 30.2 ） ms and （ 36.6 ＋ 16.5 ）} ms, P 〈 0.01 before and after PCI treatment in early AMI patients and there＇s significant differect in QTcd （76.3 ＋ 29.6） ms and （32.8 ＋ 12.2）ms, P 〈0.01. Conclusion： The PCI treatment can decrease QTd and QTcd obviously, decrease the serious arrhythmia occurrence and the sudden death.
