病毒性心肌炎患儿动态心电图及左心功能的观察

OBSERVATIONS ON DYNAMIC ELECTROCARDIOGRAMS AND LEVOCARDIA FUNCTIONS OF BABY PATIENTS WITH VIRAL MYOCARDITIS

目的：观察病毒性心肌炎患儿动态心电图及左心功能的变化；方法：对６２例该病患儿进行２４ｈ动态心电图监护和超声心动图检测ＥＦ、ＦＳ、ＣＩ，并对出现期前收缩患儿做了对比性观察；结果：心律失常乃病毒性心肌炎患儿最常见的心电异常，动态心电图的检出率（４６／６２）明显高于常规心电图（３０／６２），并且能发现常规心电图难以发现的复杂心律失常。２４ｈ心脏早搏＞１４４００次者较２４ｈ早搏＜１４４００次者左心功能明显受影响（Ｐ＜０．０５）；结论：动态心电图能全面地显示心电异常活动，提高心律失常的检出率。
