Prior to echocardiography, the recognition of serious heart disease in the cyanotic newborn or young infant could be extremely difficult. The profound hemodynamic changes taking place in the heart and lungs after birth influence the clinical manifestations of many cardiac disorders, and sometimes suggest the existence of a cardiac disorder when none is present. Real time echocardiography has revolutionalized the diagnosis of the cyanotic infant. If the reason for the infant's cyanosis or respiratory distress is not apparent from the history, physical examination, laboratory values, and chest radiograph; real time echocardiography should be performed to exclude or diagnose cyanotic congenital heart disease and persistent fetal circulation. This will prevent misdiagnosis in cyanotic infants and assure rapid and appropriate treatment.
在超声心动图检查之前，识别患有青紫型心脏病的新生儿或小婴儿的严重心脏疾病可能极其困难。出生后心肺发生的深刻血流动力学变化会影响许多心脏疾病的临床表现，有时在不存在心脏疾病时却提示存在心脏疾病。实时超声心动图彻底改变了对青紫型婴儿的诊断。如果从病史、体格检查、实验室检查结果及胸部X线片无法明确婴儿青紫或呼吸窘迫的原因，就应进行实时超声心动图检查，以排除或诊断青紫型先天性心脏病及持续性胎儿循环。这将防止对青紫型婴儿的误诊，并确保快速且恰当的治疗。
