探讨急性心肌梗死（ＡＭＩ）后室性快速心律失常室内异位激动点与梗死部位关系。方法：用心电图 （ＥＣＧ）、心电向量图（ＶＣＧ）方法，对８５例ＡＭＩ后室性快速心律失常室内异位激动点进行定位。结果：共确定出室内 异位激动点１０１个，其中左室发出的异位激动点８６个；右室发出的异位激动点１５个。在左室发出的异位激动点 中，左室前壁发出２５个，占ＡＭＩ人数２９．４１％，占室内异位激动点总数的２４．７５％；左室基底部发出２０个，占ＡＭＩ人 数的２３．５２％，占室内异位激动点总数的１９．８０％；左室间隔部发出１７个，占ＡＭＩ人数２０％，占室内异位激动点总数 的１６．８３％；左室后壁发出１５个，占ＡＭＩ人数１７．６５％，占室内异位激动点总数的１４．８５％，其他部位发出的均较少。 结论：ＡＭＩ后室性快速心律失常室内异位激动点部位与ＡＭＩ部位是一致的。
To investigate the relationship between ventricular tachycardia and infarction in ventricular tachyarrhythmia patients after acute myocardial infarction (AMI). Methods: Echocardiography (ECG) and electrocardiogram (VCG) were used to locate 85 cases of ventricular tachyarrhythmia after AMI. Results: A total of 101 indoor ectopic agonists were identified, of which 86 were ectopic ones in the left ventricle and 15 were eutopic ones in the right ventricle. In the left ventricular ectopic point of excitement, the anterior wall of the left ventricular issued 25, accounting for 29.41% of the AMI population, accounting for 24.75% of the total indoor ectopic activation points; 20 left ventricular base, accounting for AMI 23.52% of the total number, accounting for 19.80% of the total number of ectopic indoor vibration; left ventricular septum issued 17, accounting for 20% of AMI, accounting for 16.83% of the total indoor ectopic activation points; left ventricular The wall emits 15, accounting for 17.65% of the AMI population, accounting for 14.85% of the total number of ectopic extremity points in the room, and less in other sites. CONCLUSION: The location of the ventricular extracorporeal agonistic point in ventricular tachyarrhythmia after AMI is consistent with that of AMI.
