【摘要】目的 分析登革热患者心电图的特征。方法 回顾性分析302例登革热患者(登革热组)和同期300名健康体检者(对照组)的临床资料,对比2组心电图异常情况;进一步分析异常心电图治疗前后的变化及其特点。结果 登革热组存在心电图异常的患者比例(51.32%,155/302)高于对照组(31.00%,93/300)(P < 0.001);登革热组心电图异常发生频率高于对照组的有ST-T改变(27.81%,84/302)、窦性心动过缓(11.92%,36/302)(P均< 0.05);有46例心电图异常的患者治疗后复查了心电图,其中窦性心动过缓发生频率较治疗前下降,差异有统计学意义(P < 0.05);窦性心动过缓的患者共36例,16例(44.44%)合并ST-T改变,高于无窦性心动过缓的患者(25.56%,68/266),差异有统计学意义(P < 0.05)。结论 登革热患者心电图异常较普遍,主要表现为ST-T改变、窦性心动过缓;窦性心动过缓是登革热最常见的心律失常和较显著的心电图特征,可能有助于诊断登革热。

【Abstract】Objective To analyze the characteristics of the electrocardiogram (ECG) in patients with dengue. Methods Clinical data of 302 cases of dengue (dengue group) and 300 healthy subjects (control group) during the same period were retrospectively analyzed. The abnormalities of ECG were statistically compared between two groups. The changes and abnormalities of ECG before and after treatment were subsequently analyzed. Results The proportion of patients with abnormal ECG in the dengue group was 51.32%(155/302), significantly higher than 31.00%(93/300) in the control group (P < 0.001). In the dengue group, the frequency of abnormal ECG in terms of ST-T changes (27.81%, 84/302) and sinus bradycardia (11.92%, 36/302) was significantly higher than that in the control group (both P < 0.05). Forty-six patients with abnormal ECG were reexamined by ECG after corresponding treatment. Among them, the frequency of sinus bradycardia was remarkably decreased compared with that before treatment (P < 0.05). Among 36 dengue patients with sinus bradycardia, 16 cases (44.44%) had ST-T changes, and the proportion was significantly higher than 25.56% (68/266) of their counterparts without sinus bradycardia (P < 0.05). Conclusions ECG abnormalities are commonly observed in dengue patients, mainly manifested as ST-T changes and sinus bradycardia. Sinus bradycardia is the most common arrhythmia of dengue and a relatively prominent ECG feature, which may have certain hints for the clinical diagnosis of dengue.

登革热是由登革病毒引起,主要通过伊蚊叮咬传播的急性传染病,是全球分布最广、发病最多的虫媒传染病,近年来我国疫情总体上呈上升趋势,给社会造成巨大的经济和医疗负担[1-6]。登革热可并发心、肺、脑、肝、肾等器官损伤,如ARDS、急性心肌炎、急性肝损伤、急性肾损伤、脑炎等。因此,登革热患者可出现相应的心电圖异常。然而,国内外有关登革热心电图异常的报道较少,缺乏对心电图异常进行系统的描述和对照分析。本研究分析我院近7年共302例登革热患者的资料,旨在探讨登革热患者心电图异常的情况。
对象与方法
一、研究对象
选取2014年1月至2020年12月广东医科大学附属医院收治的登革热病例,临床资料及心电图资料完整者,作为登革热组;选取同期性别与年龄匹配的健康体检者作为对照组,2组均排除既往明确有冠状动脉粥样硬化性心脏病(冠心病)、高血压、其他心脏疾病或心电图异常者,排除进行心电图检查的时间段存在发热的患者。
二、诊断标准
登革热的诊断根据2018年版《中国登革热临床诊断……
