众所周知,急性心肌梗塞(AMI)可发生在心房,据报告发生率为17%。心房梗塞常并发室上性心律失常。心电图是死前诊断心房梗塞的唯一手段。本文研究目的旨在搞清心房梗塞患者入院前的心电图改变与入院后发生室上性心律失常的关系。方法:研究Aalborg医院1987年全年中第一次发作AMI住院的全部患者共550例,心电监护时发现心律失常便走纸记录。诊断MI是根据胸痛、典型心电图改变、酶水平升高。心房梗塞的心电图标准包括: 主要标准: V5、V6 PR段抬高>0.5mm,V1、V2 PR段相应压低或 I导联PR段抬高>0.5mm,Ⅱ、Ⅲ导联PR段相应压低或胸前导联PR段压低>1.5mm,Ⅰ、Ⅱ、Ⅲ导联PR段压低>1.2mm,并发房性心律失常
It is well known that acute myocardial infarction (AMI) can occur in the atrium and is reported to be 17%. Atrial infarction often complicated by supraventricular arrhythmias. ECG is the only means of diagnosing atrial infarction before death. The purpose of this study is to clarify the relationship between ECG changes before admission and patients with supraventricular arrhythmias after admission. METHODS: A total of 550 patients with AMI hospitalized for the first episode of Aalborg Hospital in 1987 were studied. Cardiac arrhythmias were recorded on paper during ECG monitoring. Diagnostic MI is based on chest pain, typical ECG changes, elevated enzyme levels. ECG standards of atrial infarction include: Main criteria: V5, V6 PR segment elevation> 0.5mm, V1, V2 PR segment corresponding depression or I lead PR segment elevation> 0.5mm, Ⅱ, Ⅲ lead PR segment corresponding depression or Prosthetic lead PR segment depression> 1.5mm, Ⅰ, Ⅱ, Ⅲ lead PR segment depression> 1.2mm, complicated by atrial arrhythmia
