在接受利尿剂治疗的高血压病人和急性心肌梗塞病人中,低血钾和室早增多的关系,各家报道不一。尽管低血钾与单纯室早的关系尚未确定,但是在急性心肌缺血时低血钾同持续性室速和室颤强相关。低血钾可以影响抗心律失常药物的效果。肾上腺素刺激β_2肾上腺能受体从而降低血钾,这可能是非选择性β受体阻滞剂预防新近心肌梗塞病人猝死的部分原因。纠正低血钾(<4.0mEq/L)的措施,则需个体化。
In diuretic patients with hypertension and acute myocardial infarction patients, the relationship between hypokalemia and ventricular premature growth, various reports vary. Although the relationship between hypokalemia and simple ventricular premature has not been established, hypokalemia is associated with persistent ventricular tachycardia and ventricular fibrillation during acute myocardial ischemia. Hypokalemia can affect the effectiveness of anti-arrhythmic drugs. Epinephrine stimulates beta 2 adrenergic receptors to lower serum potassium, which may be partly responsible for the prevention of sudden death in patients with recent myocardial infarction by non-selective beta-blockers. Correct hypokalemia (<4.0mEq / L) measures, you need to be individualized.
