The P waves begin to flatten and become wider as serum potassium increases; the PR interval may
be prolonged. The QRS complex begins to widen with potassium levels of 6.0 to 6.5 mEq/L. Also,
ST segments disappear. The T waves become narrow, tall, and peaked, sometimes described as
"tentlike." These T waves reach a height that is about 50% of the height of the QRS complex.
