摘要
[目的]应用组织多普勒成像技术(TDI)评价肥厚型心肌病(HCM)左室收缩运动协调性及功能。[方法]正常对照组18例、肥厚型心肌病患者30例。测量左室收缩期电机械运动的时间离散度(DTQ-S)、室间隔和左室侧壁6个位点的心肌收缩期峰值速率(Vs)。[结果]与对照组(15.6±3.5)ms相比,HCM组DTQ-S延长,梗阻型(31.5±12.3)ms、非梗阻型(28.2±15.2)ms均为P<0.001,而二者之间比较差异无显著性意义(P=0.623)。HCM组各位点Vs值降低(P<0.05),但是梗阻型与非梗阻型相比差异均无显著性意义。[结论]肥厚型心肌病梗阻型与非梗阻型均存在左室收缩运动协调障碍和收缩功能下降,TDI能够评价HCM左室运动而不受负荷影响。
[Objective] To assess left ventricular systolic synchrony and systolic function in hypertrophic cardiomyopathy by Tissue Doppler Imaging(TDI) technique.[Methods] Thirty patients with hypertrophic cardiomyopathy(HCM) and 18 age-matched healthy subjects as control group were performed with Pulsed TDI to record the ventricular septum and left ventricular lateral、anterior and inferior walls motion pattern in the left side atrial-ventricular annulus.The time dispersion of electromechanical motion in left ventric...
