甲状腺激素对心脏的活动有明显影响,可使心跳加快、加强。甲亢时患者心率加快心输出量增多,但组织由于耗氧量增加而相对缺氧,以至小血管舒张,外周阻力降低,因此动脉收缩压增高而舒张压正常或稍低,脉压增宽;由于心动过速,心肌可因过度耗竭,而导致心衰[1]。其临床表现多样,不典型
Thyroid hormone has a significant impact on the activity of the heart, can make the heartbeat faster and stronger. Hyperthyroidism patients with heart rate to speed up the increase in cardiac output, but tissue due to increased oxygen consumption relative hypoxia, and even small vasodilation, peripheral resistance decreased, so arterial systolic blood pressure increased diastolic blood pressure normal or slightly lower, pulse pressure widened; due to Tachycardia, myocardial over-depletion may lead to heart failure [1]. The clinical manifestations of diverse, atypical
