目的:探讨小儿病毒性心肌炎动态心电图的特点及诊断价值。方法:对河南科技大学第一附属医院106例经过临床诊断为病毒性心肌炎的患儿进行动态心电图和常规心电图监测。结果:小儿病毒性心肌炎多有心脏电活动的变化,心律失常较常见,动态心律图更易发现心电变化。出现各种心律失常者95例,占89.62%,心律失常以室性早搏、窦性心动过速、房性早搏较常见。并常合并有心电图ST-T段改变。常规心电图阳性检出率为72.60%,动态心电图阳性检出率为96.00%,两者比较有统计学差异。结论:动态心电图监测对小儿病毒性心肌炎的诊断更确切,对小儿病毒性心肌炎心律失常早期发现方面有独特的优势。对小儿病毒性心肌炎的诊断,指导临床用药及评价预后均有重要的临床意义,并可作为随访手段。
Objective: To investigate the characteristics and diagnostic value of dynamic electrocardiogram in children with viral myocarditis. Methods: 106 cases of the first affiliated hospital of Henan University of Science and Technology through clinical diagnosis of viral myocarditis in children with dynamic electrocardiogram and conventional ECG monitoring. Results: In children with viral myocarditis, there were more changes in cardiac electrical activity, arrhythmias were more common, and dynamic arrhythmia was more likely to find changes in ECG. A variety of arrhythmia occurred in 95 cases, accounting for 89.62%, arrhythmia to ventricular premature beats, sinus tachycardia, atrial premature beats more common. And often combined with ST-T ECG changes. The positive rate of routine electrocardiogram was 72.60%, and the positive rate of ambulatory electrocardiogram was 96.00%. There was a significant difference between the two. CONCLUSION: Holter monitoring is more accurate for the diagnosis of viral myocarditis in children and has unique advantages in the early detection of arrhythmia in children with viral myocarditis. The diagnosis of pediatric viral myocarditis, clinical guidance and evaluation of prognosis have important clinical significance, and can be used as a follow-up means.
