ECG changes include increased T-wave amplitude, or peaked T waves
. More severe degrees of hyperkalemia result in a prolonged PR interval andQRS duration,atrioventricular conduction delay, and loss of P waves. Progressive widening of the QRS complex and its merging with the T wave produce a sine wave pattern. The terminal event is usually ventricular fibrillation or asystole
