Hypokalemia results in slowed conduction, delayed ventricular repolarization, shortened refractory period and increased automaticity. ECG changes include flattening and inversion of T waves in mild hypokalemia, followed by Q-T interval prolongation, visible U wave and mild ST depression4 in more severe hypokalemia.
