临床上通常将心室率每分钟超过100次称为心动过速.心动过速的起搏点可来自心脏的不同部位(窦房结、心房、房室交界区、心室).通过心脏听诊只能了解心室率增快的程度,至于心动过速的性质即起搏点的部位则不能确定.各种心动过速的性质不同,临床意义和治疗措施也不完全一样,因此,正确判定心动过速的性质有着重要意义.心电图检查在确定心动过速的性质上有很大帮助,但在分析诊断时也是相当困难的.本文仅就心电图所见把临床常见的心动过速的诊断和鉴别诊断做一扼要的讨论,以供临床参考.
Clinically ventricular rate is usually more than 100 times per minute called tachycardia .Tentricular tachycardia pacemaker may come from different parts of the heart (sinus node, atrial, atrioventricular junctional area, ventricular) .Auscultation through the heart only Understanding of the ventricular rate increased, as the nature of tachycardia that the site of the pacemaker can not be determined.All kinds of tachycardia of different nature, clinical significance and treatment measures are not exactly the same, therefore, the correct determination of tachycardia The nature of the ECG has great significance in the determination of the nature of tachycardia, but in the analysis of diagnosis is quite difficult.This paper only on ECG findings to the clinical diagnosis and differential diagnosis of tachycardia do A brief discussion for clinical reference.
