本文分析30例预激综合征合并急性心肌梗塞(AMI)、阵发性室上速(PSVT)和房颤(Af)的有关几个问题,结果发现合并AMI6例,有3例病理性Q波被掩盖,2例AMI后预激综合征的心电图特征消失;合并PSVT11例,其病程在10年以上的5例,显示有随病程延长、PSVT发作变频、持续时间增长、治疗困难增加的倾向,其中3例在PSVT发作时用刺激迷走神经方法治疗,虽然发作终止,但出现2秒以上的窦停搏,而1例亨先注射阿托品0.6mg后再行刺激迷走神经治疗,未出现上述情况;合并Af8例,其中并发冠心病的5例,心室率均≤150bpm,可能是旁道也有缺血,传导功能降低所致。
This article analyzes the 30 cases of pre-excitation syndrome with acute myocardial infarction (AMI), paroxysmal supraventricular tachycardia (PSVT) and atrial fibrillation (Af) related to several issues and found that AMI 6 cases, 3 cases of pathological Q wave Were found to be masked. The electrocardiographic features disappeared in 2 cases of pre-excitation syndrome after AMI. In 11 cases with PSVT, the duration of disease was more than 10 years. The frequency of PSVT episodes increased with the prolongation of duration and the treatment difficulty increased. Three of them were treated with stimulation of vagus nerve during the onset of PSVT. Although the onset of the seizures was stopped, sinus arrest was observed for more than 2 seconds, whereas the first case of atropine 0.6 mg was injected before vagus nerve stimulation, which did not happen. The combination of Af8 Cases, of which 5 cases were complicated by coronary heart disease, ventricular rate were ≤ 150bpm, may also have side effects of ischemia, reduced conduction.
