Accurate wide QRS complex tachycardia (WCT) differentiation into either ventricular tachycardia or supraventricular wide complex tachycardia using 12‑lead electrocardiogram (ECG) interpretation is essential for diagnostic, therapeutic, and prognostic reasons. There is an ever-expanding variety of WCT differentiation methods and criteria available to clinicians. However, only a few make use of the diagnostic value of comparing the ECG during WCT to that of the patient's baseline ECG. Therefore, we highlight the conceptual rationale and scientific literature supporting the diagnostic value of WCT and baseline ECG comparison.
准确区分宽 QRS 复合心动过速（WCT）为室性心动过速或室上性宽复合心动过速，无论是出于诊断、治疗还是预后的原因，使用 12 导联心电图（ECG）解读都是至关重要的。临床医生可利用的 WCT 鉴别方法和标准种类繁多，但只有少数方法利用了比较 WCT 期间心电图与患者基础 ECG 的诊断价值。因此，我们强调了支持 WCT 和基础 ECG 比较的诊断价值的概念原理和科学文献。
