目的：探讨小儿心前区疼痛的临床特点。方法：对１０５例心前区疼痛患儿采用统一方法，包括详细的病史调查，物理诊断，胸部Ｘ线、常规心电图、Ｈｏｌｔｅｒ心电图、超声心动图检查，心肌酶谱、总血脂及胆固醇测定，并对部分患儿施行了脑电图（ＥＥＧ）检查。结果：心前区疼痛由心脏病所致者少见（占９５％），精神负担过重及过分溺爱的患儿心前区疼痛症状往往比较明显。结论：心源性心前区疼痛，必然有Ｈｏｌｔｅｒ心电图缺血性改变存在。心前区疼痛９０％以上属特发性，病因是良性的，呈自限性，而预后良好。
Objective: To investigate the clinical features of children with precordial pain. Methods: A total of 105 patients with pain in the precordial area were enrolled in this study. They included detailed medical history, physical diagnosis, chest X-ray, routine electrocardiogram, Holter electrocardiogram, echocardiography, myocardial enzymes, total lipids and cholesterol, Some children underwent an electroencephalogram (EEG) examination. Results: The pain in heart area was rare by heart disease (95%). The symptoms of pain in anterior heart area were more obvious in children who were overburdened and excessively beloved. CONCLUSIONS: Cardiac pericardial pain is necessarily associated with Holter ECG ischemic changes. More than 90% of anterior precordial pain is idiopathic, the cause is benign, was self-limiting, and the prognosis is good.
