急性心肌梗塞入院时有低血钾或低血镁者常伴有室性心律失常发生率的增高,而且入院当时的发生率常高于心肌梗塞后期。本文以血清钾及镁的水平作为连续变量,评价其与急性心肌梗塞早期室性心律失常的相关性。方法:本文研究对象系在首次急性心肌梗塞出现症状后12小时内住入冠心监护病房的患者,共60例,其中男性54例,平均年龄66.1±9.7岁,自出现症状至入院为3.8±2.5小时。本组26例为前壁梗塞,29例下壁梗塞,5例定位不明确。心律失常分为(1)室性心动过速;(2)室性早搏(PVCs)。后者又分为下列亚组:频繁单源性早搏、
Acute myocardial infarction admission hypokalemia or hypomagnesemia often accompanied by an increase in the incidence of ventricular arrhythmias, and hospital admission was often higher than the incidence of myocardial infarction. In this paper, serum potassium and magnesium levels as a continuous variable, evaluation of acute myocardial infarction and early ventricular arrhythmia correlation. Methods: In this study, 60 patients were enrolled in coronary care units within 12 hours after the first acute myocardial infarction symptoms, including 54 males (mean age 66.1 ± 9.7 years), hospitalization from symptom onset to 3.8 ± 2.5 hours. The group of 26 cases of anterior infarction, inferior wall infarction in 29 cases, 5 cases of ambiguous positioning. Arrhythmia is divided into (1) ventricular tachycardia; (2) premature ventricular contractions (PVCs). The latter is divided into the following subgroups: frequent single source of premature beats,
