小儿心血管专家遇到的首次就诊患儿中，大部分患儿有心脏杂音或胸痛。胸片（CXR）和心电图（ECG）是否能纠正小儿心血管专家依据病史和体检所定的心脏病临床诊断，一直有争论。笔者于美国某医院随访因心脏杂音（79％）或胸痛（21％）而首次就诊患儿106例，来评估CXR和ECG的价值 Most pediatric cardiologists have heart murmur or chest pain in their first visit to pediatric cardiologists. Whether chest radiographs (CXRs) and electrocardiograms (ECGs) can correct the clinical diagnosis of heart disease in pediatric cardiologists based on medical history and physical examination has been debated. I follow-up at a hospital in the United States 106 patients with first visit due to heart murmur (79%) or chest pain (21%) to assess the value of CXR and ECG
