Objectives. To examine the relationship of QRS voltages and left ventricular (LV) mass across the spectrum of individuals with different LV mass. Methods. Twenty QRS voltage measurements or combinations were determined in a consecutive series of 159 adults with an ECG and echocardiogram without previous myocardial infarction, left or right bundle branch block, pre-excitation, or electronic pacemaker. Results. The four strongest and significant correlations between QRS and LV mass were S in V4, deepest S wave in any precordial lead plus S in V4, S in V3, and S in V3 plus R in AVL times QRS duration. For men, the strength of the relationships were S in V3 (F = 33.8), deepest S wave in any precordial lead plus S V4 (F = 33.7), S in V3 plus R aVL (F = 29.9), S in V4 (F = 29.79), and deepest S in precordial leads (F = 17.9). The R wave in AVL alone did not correlate with LV mass. Criteria using the R wave in lateral precordial leads did not correlate as strongly with LV mass. For women, only S in V4 significantly correlated with LV mass. Overall, the R wave voltage in limb leads (AVL I or II) did not correlate with precordial S wave amplitudes. Univariate and multivariate analysis showed that some but not all QRS voltages correlated with each other. In multivariate analysis, using only single variables and not combination of QRS variables, the only significant relationship between QRS voltage and left ventricular mass was for men the S in V3 () and for women S in V4 () and R in V6 (). Conclusion. The S wave in V3 and V4 correlate most strongly with LV mass while the R wave in limb leads, including AVL, do not correlate.

根据老年组中从正常到增加的 LV 质量范围内的心电图估算左心室质量

目标。研究具有不同 LV 质量的个体的 QRS 电压与左心室 (LV) 质量之间的关系。方法。在连续系列的 159 名成年人中确定了 20 个 QRS 电压测量值或组合，这些成年人没有既往心肌梗塞、左或右束支传导阻滞、预激或电子起搏器的心电图和超声心动图。结果。QRS 波和 LV 质量之间的四个最强且显着的相关性是 V4 中的 S、任何心前导联中最深的 S 波加上 V4 中的 S、V3 中的 S 以及 V3 中的 S 加上 AVL 中的 R 乘以 QRS 时限。对于男性，关系强度为 V3 中的 S ( F  = 33.8)、任何心前导联中最深的 S 波加上 S V4 ( F  = 33.7)、V3 中的 S 加上 R aVL ( F  = 29.9)、V4 中的 S ( F  = 29.79），以及心前导联最深的 S（F  = 17.9）。仅 AVL 中的 R 波与 LV 质量不相关。在侧心前导联中使用 R 波的标准与左心室质量的相关性并不强。对于女性来说，只有 V4 中的 S 与 LV 质量显着相关。总体而言，肢体导联（AVL I 或 II）中的 R 波电压与心前区 S 波幅度不相关。单变量和多变量分析表明，部分但并非全部 QRS 电压彼此相关。在多变量分析中，仅使用单个变量而不是 QRS 变量组合，QRS 电压与左心室质量之间唯一显着的关系是男性 V3 中的 S（），对于 V4 中的女性 S（)和 V6 中的 R (）。 结论。V3 和 V4 中的 S 波与 LV 质量相关性最强，而肢体导联（包括 AVL）中的 R 波则不相关。
