急性心肌梗塞(AMI)早期室性心律失常的发生率较高,且是引起室速、室颤导致猝死的主要原因。本文测定70例AMI心电图(ECG)的QT间期离散度(QTd),目的是分析体表ECG的QTd增加与AMI早期室性心律失常的关系。
Acute myocardial infarction (AMI) early ventricular arrhythmias higher incidence, and is caused by ventricular tachycardia, ventricular fibrillation leading to sudden death. This article measures the QTd dispersion (QTd) of 70 AMI ECGs for the purpose of analyzing the relationship between the QTd increase in surface ECG and early ventricular arrhythmias in AMI.
