Abstract

Background

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.

Methods

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.

Results

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.

Conclusions

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.

新生儿房性心动过速Lorenz图的特点及临床分析。

背景：洛伦兹图（Lorenz plot， LP）分析提高了心律失常诊断的准确性，是一种有吸引力的心律失常诊断工具。我们探讨LP在不同类型新生儿房性心动过速分类中的应用，并评价其治疗效果和预后。方法：收集2018年1月至2023年6月96例新生儿房性心动过速动态心电图及临床资料。根据左心室的形态特征将其分为不同的房性心动过速组。分析各组患者的临床特点。结果：新生儿分为多灶性组（30%,31.25%）、房性早搏组（19%,19.79%）和房性心动过速组（47%,48.96%）。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。结论：不同LP模式的分析有助于新生儿房性心动过速的识别和分类，可提高新生儿房性心动过速的诊断效率，有助于临床医生根据房性心动过速的类型制定更好的治疗策略。

期刊介绍： The ANNALS OF NONINVASIVE ELECTROCARDIOLOGY (A.N.E) is an online only journal that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. ANE is the first journal in an evolving subspecialty that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. The publication includes topics related to 12-lead, exercise and high-resolution electrocardiography, arrhythmias, ischemia, repolarization phenomena, heart rate variability, circadian rhythms, bioengineering technology, signal-averaged ECGs, T-wave alternans and automatic external defibrillation. ANE publishes peer-reviewed articles of interest to clinicians and researchers in the field of noninvasive electrocardiology. Original research, clinical studies, state-of-the-art reviews, case reports, technical notes, and letters to the editors will be published to meet future demands in this field.
