Using Fourier phase analysis of equilibrium radionuclide angiography in both ventricles, inter- and intraventricular delays were correlated with QRS morphology and duration in 103 patients with idiopathic dilated cardiomyopathy. We found that left bundle branch block on the left axis may reflect a high intra-left ventricular dyssynchrony. A precise evaluation of the dyssynchrony appears useful because a high proportion of patients with incomplete bundle branch block, left anterior hemiblock, or "normal" QRS exhibit a marked intra-LV dyssynchrony and may respond to cardiac resynchronization therapy.
利用双心室平衡放射性核素血管造影的傅里叶相位分析,对103例特发性扩张型心肌病患者的心室间和心室内延迟与QRS形态及时限进行了相关性研究。我们发现,左轴上的左束支传导阻滞可能反映左心室内高度不同步。对不同步进行精确评估似乎很有用,因为相当一部分不完全性束支传导阻滞、左前分支阻滞或“正常”QRS患者存在明显的左心室内不同步,可能对心脏再同步治疗有反应。
