"WebTall, symmetric, peaked T waves are visible initially. Potassium > 6.5 mEq/L (> 6.5 mmol/L) causes further slowing of conduction with widening of the QRS interval, disappearance of the P wave, and nodal and escape ventricular arrhythmias. Finally, the QRS complex degenerates into a sine wave pattern, and ventricular fibrillation or asystole ensues. " - Peaked t waves vs normal
