Lorenz plot (LP) analysis enhances the accuracy of arrhythmia diagnosis and serves as an attractive diagnostic tool for patients with arrhythmias. We explored the utility of the LP in the classification of various types of neonatal atrial tachycardia and evaluated the treatment effects and prognosis.
Ninety-six newborns with atrial tachycardia had their dynamic electrocardiograms and clinical data collected between January 2018 and June 2023. They were divided into different atrial tachycardia groups based on the morphological characteristics of the LP. The clinical features of the patients in each group were also analyzed.
Neonates were divided into multifocal (30%, 31.25%), parasystole (19%, 19.79%), and atrial premature beat-induced atrial tachycardia (47%, 48.96%) groups. It was demonstrated that the prevalence of cardiac structural abnormalities, viral infections, myocardial injury, and heart failure was significantly increased in the multifocal atrial tachycardia group.
The analysis of distinct LP patterns allowed for the identification and classification of neonatal atrial tachycardia, which could improve the diagnostic efficiency of neonatal atrial tachycardia and assist clinical physicians in making better management strategies based on the type of atrial tachycardia.
洛伦兹图（LP）分析提高了心律失常诊断的准确性，是心律失常患者一种有吸引力的诊断工具。我们探讨了LP在各种类型新生儿房性心动过速分类中的应用，并评估了治疗效果和预后。
收集2018年1月至2023年6月期间96例房性心动过速新生儿的动态心电图和临床资料。根据LP的形态特征将他们分为不同的房性心动过速组。还分析了每组患者的临床特征。
新生儿分为多灶性（30%，31.25%）、并行心律（19%，19.79%）和房性早搏诱发的房性心动过速（47%，48.96%）组。结果表明，多灶性房性心动过速组心脏结构异常、病毒感染、心肌损伤和心力衰竭的发生率显著增加。
对不同LP模式的分析有助于识别和分类新生儿房性心动过速，这可以提高新生儿房性心动过速的诊断效率，并协助临床医生根据房性心动过速的类型制定更好的管理策略。
