Although electrocardiography has been used to estimate left ventricular hypertrophy and to obtain useful prognostic information in different clinical settings, its correlation with left ventricular mass is poor and, therefore, its sensitivity and specificity for the diagnosis of left ventricylar hypertrophy are low. Experimental work has demonstrated that the increase in voltage and duration of the QRS complex of the electrocardiogram are not only related to left ventricular mass but also to changes in the electrophysiological properties of the myocardium. Therefore, a new strategy is needed to use electrocardiography not to estimate left ventricular mass but aimed to add useful prognostic information.
尽管心电图已被用于评估左心室肥厚，并在不同临床环境中获取有用的预后信息，但其与左心室质量的相关性较差，因此，其诊断左心室肥厚的敏感性和特异性较低。实验研究表明，心电图QRS波群电压和时限的增加不仅与左心室质量有关，还与心肌电生理特性的变化有关。因此，需要一种新的策略来利用心电图，不是用于评估左心室质量，而是旨在增加有用的预后信息。
