摘要
室性反复搏动与插入性室性早搏是临床经常出现的两类心律失常。二者的形成机制不同,但心电图表现类似,经常容易误诊或漏诊。而Lorenz散点图对于二者的鉴别诊断有独到的优势:根据室性反复搏动和插入性室性早搏心电散点图上特征性吸引子的分布特点,能方便快速地做出诊断;利用心电散点图逆向回放技术及吸引子心搏量化工具,还能进一步对二者的诊断进行量化统计,避免对室性反复搏动的误诊和漏诊。
Ventricular reciprocal beats and interpolated ventricular premature beats(PVB)are two types of arrhythmias commonly seen in clinical practice.With different formation mechanisms and similar ECG manifestations,they are both often easy to be misdiagnosed or misssed diagnosed.Whereas Lorenz scatter plots have unique advantage in the differential diagnosis between the two types of arrhythmias.According to the distribution characte-ristics of featured attractors in the ECG scatter plots of ventricular reciprocal beats and interpolated PVB,clinicians could make diagnosis conveniently and rapidly;using the technique of ECG scatter plot retrograde playback and attractor beat quantification tool,we can further make quantitative statistics for the diagnosis of these two types of arrhythmias,so as to avoid making misdiagnosis or misssed diagnosis of ventricular reciprocal beats.
