Several factors are known to interfere with electrocardiogram (ECG) sensitivity when diagnosing Left Ventricular Hypertrophy (LVH), with gender and cardiac mass being two of the most important ones
To evaluate the influence of gender on the sensitivity of some of the criteria used to detect LVH, according to the progression of ventricular hypertrophy degree.
According to gender and the degree of LVH at the echocardiogram, the patients were divided in three groups: mild, moderate and severe LVH. ECG sensitivity to detect LVH was assessed between men and women, according to the LVH degree.
Of the 874 patients, 265 were males (30.3%) and 609, females (69.7%). The [(S + R) X QRS], Sokolow-Lyon, Romhilt-Estes, Perugia and strain criteria showed high discriminatory power in the diagnosis of LVH between men and women in the three groups with LVH, with a superior performance in the male population and highlighting the importance of the [(S + R) X QRS] and Perugia scores. Conclusion: The diagnostic sensitivity of the ECG increases with the cardiac mass. The examination is more sensitive in men, highlighting the importance of the [(S + R) X QRS] and Perugia scores.

已知有几个因素会干扰心电图（ECG）在诊断左心室肥厚（LVH）时的敏感性，其中性别和心脏质量是最重要的两个因素。
根据心室肥厚程度的进展，评估性别对一些用于检测 LVH 的标准敏感性的影响。
根据性别和超声心动图上的 LVH 程度，将患者分为三组：轻度、中度和重度 LVH。根据 LVH 程度评估心电图检测 LVH 的敏感性在男性和女性之间。
在 874 名患者中，男性 265 名（30.3%），女性 609 名（69.7%）。在三组 LVH 患者中，[(S + R) X QRS]、Sokolow-Lyon、Romhilt-Estes、Perugia 和应变标准在男性和女性之间对 LVH 的诊断具有较高的鉴别力，在男性人群中的表现更好，并突出了[(S + R) X QRS]和 Perugia 评分的重要性。结论：心电图的诊断敏感性随心脏质量的增加而增加。该检查在男性中更敏感，突出了[(S + R) X QRS]和 Perugia 评分的重要性。
