[Article] POTASSIUM and ARRHYTHMIAS: Exploring the effects of potassium in the cardiac rhythm

Potassium plays a central role in keeping the heart’s electrical activity stable, and even small shifts in its level can influence rhythm. This article briefly explains how potassium supports normal conduction and ECG changes that help clinicians recognize hypokalemia early. A brief review of hypokalemia management provides practical context, before moving into the updated arrhythmia guidelines, emphasizing how potassium balance and treatments fit the current approach to cardiac rhythm disorders.
