Electrolyte disorders and arrhythmia

A number of electrolytes play a role in the genesis of the transmembrane action potential.Electrolyte disorders can alter cardiac ionic currents kinetics and depending on the changes can promote proarrhythmic or antiarrhythmic effects.The present report reviewed the mechanisms, electrophysiological, electrocardiographic, and clinical consequences of electrolyte disorders. Key words: Arrhythmias; Hypokalemia; Hyperkalemia; Hypocalcemia; Hypercalcemia; Electrolyte
