背景:典型的心电图(ECG)劳损图形[V5和(或)V6导联劳损改变]与左室肥厚(LVH)和左室(LV)舒张功能障碍有关,但其是否与左室舒张功能障碍独立相关尚不明确。方法:LIFE研究纳入心电图提示有LVH的高血压患者,其中10%进行了多普勒超声心动图检查。检查左室舒张功能的指标包括:二尖瓣E波、A波峰流速及E/A比值;E波减速时间(EDT);心房充盈分数(AFF);等容舒张时间(IVRT)。
Background: A typical ECG strain pattern [strain change in V5 and / or V6 leads] is associated with left ventricular hypertrophy (LVH) and left ventricular (LV) diastolic dysfunction but is independent of left ventricular diastolic dysfunction The relevance is not clear yet. METHODS: LIFE included 10% of patients with LVH in the electrocardiogram (ECG) suggestive of Doppler echocardiography. Indicators of left ventricular diastolic function include: mitral E wave, A wave velocity and E / A ratio; E wave deceleration time (EDT); atrial filling fraction (AFF); isovolumic relaxation time (IVRT).
