为进—步了解急性心肌梗死溶栓治疗中再灌注心律失常的主要形式及特点,观察尿激酶静脉溶栓治疗43例急性心肌梗死患者,其中27例临床判定再通,再通率62.79％,再灌注心律失常发生率以室性期前收缩(48.50％)和加速性心室自主节律(44.44％)为高,且后者与梗死组相比意义显著(P<0.01)。其特点为一过性,可自行终止,不转为恶性室性心动过速;且与胸痛缓解、ST段回降及酶峰前移的符合率明显高于未通组。认为加速性心室自主节律是溶栓后再灌注心律失常的特殊形式,可作为判定再通可靠的无创性指标之一。
To further understand the main forms and characteristics of reperfusion arrhythmia in thrombolytic therapy of acute myocardial infarction, observe the intravenous thrombolytic therapy of urokinase in 43 patients with acute myocardial infarction, of which 27 cases of clinical judgment recanalization, the recanalization rate of 62.79% The incidence of reperfusion arrhythmia was higher in ventricular premature ventricular contraction (48.50%) and accelerated ventricular autonomic rhythm (44.44%), and the latter was significant compared with infarction group (P <0.01). Its characteristics are transient, can be terminated on their own, not to malignant ventricular tachycardia; and with chest pain relief, ST segment back drop and enzyme peak forward was significantly higher than the non-compliance group. That accelerated autonomic rhythm is a special form of reperfusion arrhythmia after thrombolytic therapy, which can be used as a reliable noninvasive indicator of recanalization.
