自先天性心脏病外科治疗开展以来,要求对心脏情况的诊断更为精确,临床虽在施行心导管及心血管造影术检查,但对诊断及鉴别先天性心脏病仍嫌复杂困难。Cosby提出心电图检查对诊断先天性心脏病较其他方法更为重要。在诊断先天性心脏病时肯定心脏不同房室部分的肥厚极为重要,心电图在确定此点较 X 线诊断为佳,有时虽有极显著的心脏某一部分的肥厚,但出于肥厚部分推移心脏引起极度转位,致使 X 线的正常部位改变,造成诊断困难。
Since the surgical treatment of congenital heart disease, heart conditions require more accurate diagnosis, although the clinical implementation of cardiac catheterization and cardiovascular imaging, but the diagnosis and identification of congenital heart disease is still too complicated and difficult. Cosby proposed ECG is more important for the diagnosis of congenital heart disease than other methods. In diagnosing congenital heart disease, it is important to confirm the hypertrophy of different parts of the heart. ECG determination is better than X-ray in determining this point. Sometimes, although there is a very significant part of the hypertrophy of the heart, Extreme transposition, resulting in the normal part of the X-ray changes, resulting in diagnosis difficult.
