摘要
目的：心电图左心室肥厚（ECG LVH）在心血管疾病中具有重要的临床意义。导致左心室肥厚（LVH）的病理过程也会诱发重塑并损害左心房（LA）功能。心房功能可通过斑点追踪超声心动图进行评估。本研究探讨了心电图 LVH 对 LA 应变的潜在影响：方法：共纳入 62 名根据超声心动图左心室质量指数诊断为左心室肥厚的患者。心电图 LVH 采用以下既定方案进行评估：Sokolow-Lyon 电压标准（SV1 + RV5/RV6 > 35 mm）、康奈尔电压标准（RaVL + SV3 > 28 mm（男性）和 > 20 mm（女性））以及康奈尔乘积标准[（SV3 + RaVL +（女性为 8 mm）] x QRS 持续时间 > 2440 mm x ms）。根据是否存在心电图 LVH 将参与者分为两组。探讨了 LA 应变测量与心电图特征之间的关系：研究对象的中位年龄为（58.3 ± 10.1）岁，女性占 40.3%，高血压患者占 91.9%，糖尿病患者占 35.5%。根据索科洛-里昂电压、康奈尔电压或康奈尔乘积标准，19 名患者（30.6%）被确定为心电图 LVH。这些患者的 LA 储腔、导管和收缩应变均明显降低（P < 0.001）。在所有三个阶段的 LA 应变测量值与 Sokolow-Lyon 电压（储能 r = -0.389，P < 0.01；导管 r = -0.273，P < 0.05；收缩 r = -0.359，P < 0.01）、康奈尔电压（水库 r = -0.49，P <0.001；导管 r = -0.432，P <0.001；收缩 r = -0.339，P <0.01）和康奈尔乘积（水库 r = -0.471，P <0.001；导管 r = -0.387，P <0.01；收缩 r = -0.362，P <0.01）：结论：ECG LVH与LA应变受损有关，可作为预测LA功能障碍的有效工具。
Left Ventricular Hypertrophy Findings on Electrocardiogram Predict Impaired Left Atrial Functions.
Objective: Electrocardiographic left ventricular hypertrophy (ECG LVH) holds significant clinical importance in cardiovascular disease. Pathological processes that lead to left ventricular hypertrophy (LVH) also induce remodeling and impair left atrial (LA) function. Atrial function can be assessed using speckle-tracking echocardiography. This study investigates the potential impact of ECG LVH on LA strain.
Methods: A total of 62 individuals diagnosed with LVH, based on the echocardiographic left ventricular mass index, were included. ECG LVH was assessed using established protocols: the Sokolow-Lyon voltage criteria (SV1 + RV5/RV6 > 35 mm), Cornell voltage criteria (RaVL + SV3 > 28 mm for men and > 20 mm for women), and the Cornell product criteria [(SV3 + RaVL + (for women 8 mm)] x QRS duration > 2440 mm x ms). Participants were categorized into two groups based on the presence or absence of ECG LVH. The relationship between LA strain measures and ECG characteristics was explored.
Results: The study population had a median age of 58.3 ± 10.1 years, with 40.3% being female, 91.9% hypertensive, and 35.5% diabetic. Nineteen patients (30.6%) were identified with ECG LVH based on Sokolow-Lyon voltage, Cornell voltage, or Cornell product criteria. These patients exhibited significantly reduced LA reservoir, conduit, and contraction strains (P < 0.001). Statistically significant correlations were observed between all three phases of LA strain measures and Sokolow-Lyon voltage (reservoir r = -0.389, P < 0.01; conduit r = -0.273, P < 0.05; contraction r = -0.359, P < 0.01), Cornell voltage (reservoir r = -0.49, P < 0.001; conduit r = -0.432, P < 0.001; contraction r = -0.339, P < 0.01), and Cornell product (reservoir r = -0.471, P < 0.001; conduit r = -0.387, P < 0.01; contraction r = -0.362, P < 0.01).
Conclusion: ECG LVH is associated with impaired LA strain, validating its use as an effective tool for predicting LA dysfunction.
