Lown分级在原发性高血压室性心律失常风险评估中的价值重估

Reassessment of the Value of Lown Classification in Risk Assessment of Ventricular Arrhythmia in Essential Hypertension

摘要: 室性心律失常作为原发性高血压患者常见的心血管并发症，其早期风险评估对预防严重心脏事件具有重要意义。Lown分级系统作为评估室性心律失常严重程度的传统工具，长期以来在临床实践中被广泛应用。然而，随着心电监测技术和心律失常研究的不断进步，Lown分级在现代医学背景下的适用性和准确性面临新的挑战和讨论。本文综述了Lown分级的历史发展及其评估指标，系统梳理了近年来关于其与心律失常预后相关性的研究成果，重点分析其在原发性高血压患者中的风险评估价值。同时，结合新兴的心电监测技术和其他风险评估工具，探讨了Lown分级的优势与局限，旨在为高血压患者的心律失常风险分层和精准管理提供科学依据，促进临床决策的优化和患者预后改善。

Abstract: Ventricular arrhythmia, as a common cardiovascular complication in patients with essential hypertension, holds significant importance in early risk assessment for preventing severe cardiac events. The Lown classification system, a traditional tool for evaluating the severity of ventricular arrhythmias, has been widely used in clinical practice for a long time. However, with continuous advancements in electrocardiographic monitoring technology and arrhythmia research, the applicability and accuracy of the Lown classification face new challenges and discussions in the context of modern medicine. This article reviews the historical development and evaluation criteria of the Lown classification, systematically summarizes recent research findings on its correlation with arrhythmia prognosis, and focuses on analyzing its value in risk assessment among patients with essential hypertension. Additionally, by integrating emerging electrocardiographic monitoring technologies and other risk assessment tools, the advantages and limitations of the Lown classification are discussed. The aim is to provide a scientific basis for arrhythmia risk stratification and precision management in hypertensive patients, thereby promoting the optimization of clinical decision-making and improving patient outcomes.
