Echocardiographic parameters of left ventricular (LV) function were compared with the electrocardiographic findings in 40 patients with chronic severe aortic regurgitation. Total 12-lead QRS amplitude was linearly correlated with LV mass and its 'relative reduction' (less than 250 mm) indicated LV hypertrophy. Patients with an electrocardiographic 'strain' pattern had a marked increase LV stress (573 +/- 68 dyn). The association of high total 12-lead QRS amplitude and 'strain' indicate a moderately depressed ejection fraction (EF = 43 +/- 3). Finally, 'strain' and a 'relative reduction' of total 12-lead QRS amplitude were present in patients with a severe depression of EF and contractility. The predictive value of these electrocardiographic indices was confirmed during a mean follow-up of 49 months. In conclusion, the electrocardiogram remains an excellent, easy tool for anatomical and functional investigation of patients with aortic regurgitation.
对40例慢性重度主动脉瓣反流患者的左心室（LV）功能超声心动图参数与心电图表现进行了比较。12导联QRS总振幅与左心室质量呈线性相关，其“相对降低”（小于250mm）提示左心室肥厚。有心电图“劳损”图形的患者左心室压力显著升高（573±68达因）。12导联QRS总振幅高与“劳损”相关，提示射血分数中度降低（EF = 43±3）。最后，在射血分数和收缩力严重降低的患者中存在“劳损”和12导联QRS总振幅“相对降低”。在平均49个月的随访期间证实了这些心电图指标的预测价值。总之，心电图仍然是用于主动脉瓣反流患者解剖和功能检查的优秀且简便的工具。
