快速诊断室性心动过速的新方法——图形法

Figure method:a new approach to quick diagnosis of ventricular tachycardia

室性心动过速是临床上需要紧急处理的严重心律失常,如何运用体表心电图准确、快速地诊断室速仍是临床医师面临的一个难题。笔者根据室速发生的起源部位不同,体表心电图分别具有不同的特异性表现,通过临床仔细分析大量心电图,并根据室速起源的部位分类,总结出了一种快速、简便且准确率高的诊断室速的新方法——图形法。为验证该新方法的诊断准确率,收集2011年1月至2013年12月在我院经心脏电生理检查明确诊断为室性心动过速的患者的280份室速发作时的12导联体表心电图,全部运用图形法对其进行分析,其中有177份符合图形法的诊断条件,诊断符合率为63.21%。图形法简便、快速、高效,易被临床专科和非专科医师掌握,适用于临床的需要。

Ventricular tachycardia has always been an acute arrhythmia which needs urgent treat-ment.However it is still difficult for clinicians to find an accurate and quick method to diagnose it by traditional 12-lead electrocardiogram（ECG）.According to the fact that surface ECG shows dif-ferent characteristics with different origins of ventricular tachycardia,we carefully analyzed a large number of ECGs.By the classification of origins of ventricular tachycardia,we summarized a new approach,figure method,which was quick,convenient and accurate in diagnosing the disease.In order to testify the diagnostic accuracy of this new method,we collected 280 12-lead surface ECGs when ventricular tachycardia attacked and these ECGs were belonging to patients who had been spe-cifically diagnosed with the disease by electrophysiologic examinations from January 201 1 to Decem-ber 2013 in our hospital.Figure method was utilized in the analysis of those ECGs,among which 177 ones coincided with diagnostic conditions of the new method,with a coincidence rate of 63.21%.This paper manifests the convenience,rapidity and high efficiency of figure method and it is also easy to be mastered by cardiologist and non-cardiovascular clinicians.The new method fits well for clinical requirements.
