For proper distribution of preventative resources, a more robust method of cardiac risk stratification should be encouraged in addition to merely reduced ejection fraction. To this end, the QRS-T angle, an electrocardiogram-derived measure of the difference in mean vectors of depolarization and repolarization, has been found associated with sudden cardiac death and other mortal and morbid outcomes in multiple observational studies over the past decade. The use of both frontal and spatial QRS-T angle in the prediction of future cardiac events including sudden cardiac death, all-cause mortality, and further cardiac morbidity is reviewed here.
为了合理分配预防资源，除了单纯的射血分数降低外，还应鼓励采用更强大的心脏风险分层方法。为此，在过去十年的多项观察性研究中，已发现QRS-T角（一种从心电图得出的反映去极化和复极化平均向量差异的指标）与心源性猝死及其他死亡和发病结局相关。本文综述了使用额面和空间QRS-T角预测未来心脏事件，包括心源性猝死、全因死亡率和进一步的心脏发病率的情况。
