正常情况下,人体液中的电解质维持动态平衡,疾病或其他因素可破坏其平衡状态造成电解质紊乱。严重的电解质紊乱可引起心肌细胞激动起源和传导异常,甚至引起心室纤颤或心脏停搏。在各种电解质中,钾对心肌细胞影响最为明显。随着医学的快速发展,医疗技术的提高和透析治疗的普及以及心电图一过性改变难以记录捕捉的特点,窦室传导心电图越来越罕见,故探讨高血钾致窦室传导心电图改变及其临床意义具有重要意义。
Under normal circumstances, the electrolyte in human body fluid to maintain a dynamic balance, disease or other factors can destroy the equilibrium state caused by electrolyte imbalance. Serious electrolyte imbalance can cause cardiac muscle activation and abnormal conduction, and even cause ventricular fibrillation or cardiac arrest. Among various electrolytes, potassium has the most obvious effect on cardiomyocytes. With the rapid development of medicine, the improvement of medical technology and the popularization of dialysis treatment and the transient changes of ECG, it is difficult to record and capture the characteristics of sinus ventricular conduction ECG is rare, so to explore hyperkalemia-induced sinus conduction ECG changes and their Clinical significance is of great significance.
