Abstract

Nowadays, electrocardiogram (ECG) changes are one of the valuable diagnostic clues for recognizing abnormalities. Potassium is one of the essential electrolytes in cardiac cells, and its variations affect ECG. Potassium disorders, including hyperkalemia and hypokalemia in authoritarian states, may lead to heart dysfunctions and could be life-threatening, and urgent interventions are needed in this conditions. The current review summarizes studies to elucidate the correlation between potassium disorders and ECG demonstrations. In this review, we summarized ECG changes related to hyperkalemia and interventions. Moreover; animal studies on ECG changes related to hyper- and hypokalemia are provided. The studies showed peaked T wave, as well as expanded QRS complex and low P amplitude, are important changes that can guide us to immediate diagnosis. ECG Changes in severe hyperkalemia that can endanger patients' lives are noteworthy. Manifestations change in hyperkalemia, for correct diagnosis clinical history of the patients is essential.

钾障碍的心电图频率变化:叙述性回顾。

目前，心电图变化是识别异常的有价值的诊断线索之一。钾是心肌细胞中必需的电解质之一，其变化影响心电图。钾障碍，包括专制国家的高钾血症和低钾血症，可能导致心脏功能障碍并可能危及生命，在这种情况下需要紧急干预。本文综述了阐明钾障碍与心电图表现之间相关性的研究。在这篇综述中，我们总结了与高钾血症相关的心电图变化和干预措施。此外;提供了与高和低钾血症相关的心电图变化的动物研究。研究表明，T波的峰值、QRS复合体的扩大和P振幅的降低是可以指导我们立即诊断的重要变化。严重高钾血症的心电图变化可能危及患者的生命，值得注意。高钾血症的表现变化，对于正确诊断患者的临床病史至关重要。
