摘要
为探讨心室起搏患者并发急性心肌缺血和梗死的心电图诊断 ,笔者回顾分析了 30例右室起搏、3例冠状T波和 2 0例起搏后急性心肌缺血或梗死患者的心电图变化。结果 :①T波电张力调整性改变主要出现在Ⅱ、Ⅲ、aVF导联 ,也可影响胸前导联 ;②冠状T波者起搏后T波可转为低平 ;③任何部位急性心肌缺血和梗死 ,均可见ST段和T波的改变 ,有些部位梗死后的q(Q)波和R波的变化仍可显示出来 ,而有些部位将会被掩盖。自身心律时梗死图形与非起搏者基本相同。结论 :分析起搏患者并发心肌梗死的心电图时应结合临床症状、心电图动态变化、症状期前后的心电图对比。
This study is to evaluate the electrocardiographic diagnosi s of acute myocardial infarct and ischemia in patients with ventricular pacing.3 0 cases with ventricular pacing(as control),3 cases with coronary T wave and 20 cases with acute myocardial infarction and ischemia after ventricular pacing wer e included in this study. Result:①T wave electronic modulation mainly appeared in Ⅱ,Ⅲ and aVF leads,bu t also influenced the precardial leads;②The T wave could be become flat in pati ents after ventricular pacing;③The changes of ST segment and T wave could be seen in any location of acute myocardial infarction,the changes of q(Q) wave an d T wave were still funded in some location of infarction,however these changes might be concealed.The figure of infarction in the intrinsic cardiac rhythm was the same as in patients without pacemaker.Conclusion:Analysis of the electrocard iogram of myocardial infarction in patients with pacemaker should combine clinic al symptoms with elecrtocardiographic changes,and compare the electrocardiogram before with after myocardial infarction and observe enzyme changes.[ Chinese J ournal of Cardiac Pacing and Electrophysiology, 2003,17(1):42～45]
