The electrocardiographic transient display of left ventricular hypertrophy (LVH), during rapid heart rates, in the setting of sinus/supraventricular tachycardias and atrial fibrillation, is illustrated via 3 case reports. This common occurrence is expressed by an increase in the S-waves in leads V2-V5, during tachycardias, rendering a false positive diagnosis of LVH by the frequently employed Cornell voltage LVH criteria. This tachycardia-mediated apparent LVH, is unrelated to the occasionally encountered stable, and unrelated to tachycardia, "false positive diagnosis of LVH", which could in reality occasionally reflect altered electrical properties of myocardium that could create a functional substrate for developing arrhythmias. The importance of awareness of this insight by all health professionals is immeasurable, considering that a false positive diagnosis of LVH has major consequences in the management, prognostication, resort to expensive unnecessary testing, and stress to the patients and their families.
通过 3 个病例报告说明了在窦性/室上性心动过速和心房颤动的情况下，快速心率时左心室肥厚（LVH）的心电图瞬态显示。这种常见的现象表现为在心动过速期间导联 V2-V5 中的 S 波增加，从而通过经常使用的 Cornell 电压 LVH 标准得出 LVH 的假阳性诊断。这种心动过速介导的明显 LVH 与偶尔出现的稳定且与心动过速无关的“LVH 的假阳性诊断”无关，实际上偶尔可能反映心肌电特性的改变，从而为心律失常的发展创造功能性底物。考虑到 LVH 的假阳性诊断对管理、预后、不必要的昂贵测试的使用以及对患者及其家人的压力有重大影响，因此所有医疗保健专业人员对此认识的重要性是不可估量的。
