Abstract
Left ventriculograms of 20 patients with hypertrophic cardiomyopathy were digitised frame by frame and analysed using a contour display. Abnormalities of regional wall movement were present in 17, and included an abnormal sequence of inward movement during systole (13), regional delay in the onset of inward movement (10), and an abnormal dispersion of peak velocities (5). Diastolic wall movement was disturbed in 13, because of abnormal peak velocities in 7 and regional asynchrony in 6. Abnormal wall movement during the two isovolumic periods was rare in hypertrophic cardiomyopathy, unlike ischaemic heart disease. These disturbances may reflect underlying structural abnormalities.
摘要
对20例肥厚型心肌病患者的左心室造影片进行逐帧数字化处理，并使用轮廓显示进行分析。17例存在局部室壁运动异常，包括收缩期内向运动顺序异常（13例）、内向运动起始局部延迟（10例）以及峰值速度异常离散（5例）。13例舒张期室壁运动受到干扰，其中7例是由于峰值速度异常，6例是由于局部不同步。与缺血性心脏病不同，肥厚型心肌病在两个等容期的室壁运动异常很少见。这些异常可能反映了潜在的结构异常。
