The predictive value of various ECG repolarization markers for the emergence of VA in patients with TTS was reviewed. The literature reports on QT, more recently on Tpe, and rarely on some more QT-derived metrics, revealing a contribution of these variables for the prediction of VA, complicating the acute, subacute, and follow-up clinical trajectory of patients with TTS. More recent literature reveals that Tpe and some other QT-based metrics, have outperformed the traditionally employed QT marker, although certainty about this awaits confirmation by future carefully designed and implemented studies.
我们回顾了各种心电图复极标志物对 TTS 患者出现室速（VA）的预测价值。文献报道了 QT、最近的 Tpe 以及很少的一些基于 QT 的衍生指标，这些变量对 VA 的预测有一定的作用，使 TTS 患者的急性期、亚急性期和随访期临床病程变得复杂。最近的文献表明，Tpe 和其他一些基于 QT 的指标的表现优于传统的 QT 标志物，尽管这一结果还需要未来精心设计和实施的研究来进一步证实。
