本文对30例无并发症的急性心肌梗塞发病后4周的病人进行了心率限制性踏车运动试验,阳性率为46.7%。在平均18个月的随访期间,运动试验阳性者发生心源性猝死1例,再发性心肌梗塞2例,不稳定性心绞痛4例。本文对运动中升压反应不良和室性心律失常对判断预后的意义和急性心肌梗塞后早期运动试验阳性的判定标准进行了讨论。
In this paper, 30 patients with uncomplicated acute myocardial infarction 4 weeks after the onset of heart rate limiting treadmill exercise test, the positive rate was 46.7%. During an average of 18 months of follow-up, one of the patients with positive exercise tests developed sudden cardiac death, two with recurrent myocardial infarction, and four with unstable angina. This article discusses the significance of adverse exercise-induced dysrhythmias and ventricular arrhythmias in judging the prognosis and the criteria for the determination of positive early exercise tests after acute myocardial infarction.
