The discrimination of ventricular tachycardia (VT) versus supraventricular wide complex tachycardia (SWCT) via 12-lead electrocardiogram (ECG) is crucial for achieving appropriate, high-quality, and cost-effective care in patients presenting with wide QRS complex tachycardia (WCT). Decades of rigorous research have brought forth an expanding arsenal of applicable manual algorithm methods for differentiating WCTs. However, these algorithms are limited by their heavy reliance on the ECG interpreter for their proper execution. Herein, we introduce the Mayo Clinic ventricular tachycardia calculator (MC-VTcalc) as a novel generalizable, accurate, and easy-to-use means to estimate VT probability independent of ECG interpreter competency. The MC-VTcalc, through the use of web-based and mobile device platforms, only requires the entry of computerized measurements (i.e., QRS duration, QRS axis, and T-wave axis) that are routinely displayed on standard 12-lead ECG recordings.

Mayo Clinic VT 计算器：准确区分广泛复杂性心动过速的实用工具

通过 12 导联心电图 (ECG) 区分室性心动过速 (VT) 与室上性宽 QRS 波心动过速 (WCT) 患者对于实现适当、高质量和具有成本效益的护理至关重要。数十年的严格研究已经带来了不断扩大的适用手动算法方法库，用于区分 WCT。然而，这些算法因其严重依赖心电图解释器才能正确执行而受到限制。在此，我们介绍 Mayo Clinic 室性心动过速计算器 (MC-VTcalc)，作为一种新颖的通用、准确且易于使用的方法，可独立于心电图解释员能力来估计 VT 概率。MC-VTcalc 通过使用基于网络和移动设备平台，仅需要输入通常显示在标准 12 导联心电图记录上的计算机测量值（即 QRS 持续时间、QRS 轴和 T 波轴） 。
