摘要
为鉴别病毒性心肌炎与心脏自主神经功能紊乱引起的心电图异常,观察90例急性轻型病毒性心肌炎与91例心脏自主神经功能紊乱患儿的24h动态心电图。结果发现:心肌炎组最低心率及平均心率显著高于神经功能紊乱组;心律失常昼夜发生,期前收缩频率684—45210次/24h,严重度Ⅱ级或Ⅱ级以上;复极异常24h呈持续状态。而神经功能紊乱组心律失常呈日间型或夜间型,频率<115次/24h,严重度Ⅰ级;复极异常与窦性心动过速发生时间一致。认为上述特点有助于临床鉴别轻型病毒性心肌炎与自主神经功能紊乱。
Purpose of this study was to differential myocarditis from disturbance of vegetative nervous function of heart shown in ambulatory electrocardiograms. Ninety (90) patients with acute mild myocarditis and another 91 disturbance of vegetative nervous disease (DVND) were studied dynamically. 24h lowest rate and average heart rate in patients with myocarditis showed to be prominently higher than those with disturbance of DVND, in whom constant tachycardia was detected. Frequency of premature contractors were 684-45 210 beats/24h and grade of arrhythmia wasⅡ or over Ⅱ. Myocardial -repolarization showed circa-dian abnormalities. Arrhythmia was seen during day or night in DVND group. Frequency of premature contractions were below 115 beats/24h and was gradeI.Myocardial repolarization of abnormality was in assiociation with sinus tachycardia. Result is helpful in differentiating mild virus myocarditis from DVND.
