心电图房颤波振幅的临床意义

122例心房颤动（房颤）患者，测量心电图（ECG）平均房颤波振幅，了解其与病因诊断和超声心动图（UCG）测量左房内径（LAD）大小之间的相关性。发现慢性房颤和风湿性心脏病（风心病）房颤的平均房颤波振相及左房大小比阵发性房颤及冠状动脉硬化性心脏病（冠心病）房颤大得多（P＜0．01），平均房颤波振幅与UCG测量的左房内径大小呈正相关（r＝0．482，P＜0．01）。且风心病以粗房颤波为主，多数呈慢性房颤伴左房大；冠心病及其他疾患以细房颤波及阵发性房颤居多，并且左房大小正常。

The relation of fibrillatory wave amplitude with etiology

Electrocardiographic (ECG) fibrillatory wave amplitude was measured in 122 patients with atrial fibrillation in order to comprehend their proble role in etiologic diagnosis and correlation with the size the left atrium diameter(LAD) which was measured by use of ultracardiography (UCG). The results showed that the averege. fibrillatory wave amplitude and the size of LAD of rheumatic heart disease and chronic fibrillation were mostly larger than that of coronary artery disease and paroxysmal fibrillation(P<0. 01 ) . Averege fibrillatory wave amplitude was strongly positive correllation with the size of LAD measured by UCG (r= 0. 482 P< 0. 01 ). The electrocardiographic fibrillatory wave marked chiefly rough chronic fibrillation with the enlargement of left atrium in rheumatic heart disease and mostly fine paroxysmal fibrillation with normal left atrium in coronary artery disease and other disease.
