高钾血症可致多种类型心脏传导阻滞,但引起心室内传导阻滞者较少.现将我院遇见的4例患者的临床和心电图资料简介如下(见附表).讨论细胞外K~(+)增高时,心肌细胞膜内外K~(+)浓度差减小,静息膜电位减低而致O位相上升速率和幅度减低,邻近细胞间的传导速度减慢.这种作用可发
Hyperkalemia can cause many types of heart block, but caused less ventricular conduction block. Now in our hospital to meet the 4 patients with clinical and ECG data is as follows (see Annex) .Extracellular When K ~ (+) increased, the difference of K ~ (+) concentration in myocardial cells decreased and the resting membrane potential decreased and the rate of increase of O phase decreased and the conduction velocity of adjacent cells slowed down.
