Hyperkalemia (Fatal Ventricular Dysrhythmias) Progressive of EKG changes: Peaked T waves --> depressed ST segments --> decreased amplitude of R waves --> prolonged PR interval --> small or absent P waves --> wide QRS complexes --> sine wave pattern; With severe Hyperkalemia PR prolongation occurs, the
P wave flattens and is lost, and the QRS widens and can progress to
Ventricular Fibrillation;
