本文观察了超声心动图高血压病左室肥厚患者心律失常的发生及其与血浆儿茶酚胺的关系。结果表明,高血压性左室肥厚患者室性心律失常的发生率较单纯高血压组显著增加;血浆去甲肾上腺素与左室后壁厚度及左室重量指数显著正相关;肾上腺素与左室重量指数显著正相关;24 h室性早搏总数与血浆去甲肾上腺素及肾上腺素均显著正相关。这提示,交感—肾上腺素系统活性增强是导致高血压病心肌肥厚及室性心律失常的重要因素之一。
This article observes the echocardiographic hypertension in patients with left ventricular hypertrophy arrhythmia and its relationship with plasma catecholamines. The results showed that the incidence of ventricular arrhythmia in hypertensive patients with left ventricular hypertrophy was significantly higher than that in patients with hypertension alone. Plasma norepinephrine was positively correlated with left ventricular posterior wall thickness and left ventricular mass index. Weight index was significantly positive correlation; 24 h premature ventricular total plasma and norepinephrine and epinephrine were significantly correlated. This suggests that sympathetic - adrenergic system activity is one of the important factors leading to hypertensive cardiac hypertrophy and ventricular arrhythmia.
