本文以判别式分析法(discriminant analysis)判断急性心肌梗塞(AMI)时血流动力学变化与发生心房颤动(AF)的关系,以及 AF 本身对住院病死率的影响。研究对象为胸痛开始48h 内顺序住院的102例AMI 患者,均以动态心电图监测 AF;用 Swan-Ganz 心导管测定心排血量、肺毛细血管楔压、右房压等血流动力学参数。结果住院最初3日内18例发生 AF(组1),84例无 AF(组2)。所有 AF 发作均短暂,且可自行恢复或在治疗后恢复窦性心律。住院期死亡23
This article uses discriminant analysis to determine the relationship between hemodynamic changes and atrial fibrillation (AF) in patients with acute myocardial infarction (AMI) and the effect of AF itself on in-hospital mortality. The subjects were 102 AMI patients who were hospitalized within 48 hours after the start of chest pain. AF was monitored by Holter monitoring. The hemodynamic parameters such as cardiac output, pulmonary capillary wedge pressure and right atrial pressure were measured by Swan-Ganz cardiac catheterization. Results In the first 3 days of hospitalization, 18 cases had AF (group 1) and 84 cases had no AF (group 2). All AF episodes are transient and can be self-healing or recovering from sinus rhythm after treatment. Inpatient deaths 23
