【摘要】 目的 探索高血压病患者心房除极向量与左室舒张功能的关系。方法 应用超声心动图和心电向量图技术对100例高血压病患者进行分析。结果 高血压左室肥厚和非左室肥厚组心房除极向量最大向量振幅(MVA)、最大下向量振幅(MDVA)、最大后向量振幅(MBVA)、最大左向量振幅(MLVA)及总运行时间(TMT)均显著大于对照组(P<0.001)；超声心动图A/E与MBVA、MLVA、TMT、MVA及MDVA呈高度线性相关(r=0.78～0.41，P<0.01～0.001)。结论 结果提示心房除极向量定量分析有助于评价高血压病左室舒张功能障碍，并且早于超声心动图心功能指标的变化。

    【Abstract】 Objective To investigate therelationship between atrial depolarization vector (ADV) and left ventricular diastolicfunction.Methods One hundred patients withhypertension and 50 healthy controls were studied by echocardiography andvectorcardiography. Results The results showed thatMVA, MDVA, MBVA, MLVA and TMT of the hypertensive patients with or without leftventricular hypertrophy (LVH) were significantly higher than those of the healthy controls(P<0.001). Significant linear correlations were found between A/E of echocardiographyand MBVA, MLVA, TMT, MVA and MDVA (r=0.78-0.41; P<0.01-0.001). Conclusions The results suggest that quantitative analysis of ADV might behelpful to evaluate the disorder of left ventricular diastolic function. Furthermore, thechange of ADV might be earlier than that of echocardiogphy.
