A Very Wide Complex

What do you think of this ECG from a critically ill patient?See BelowI can only give minimal information in order to protect identity: this patient had such severe rhabdomyolysis (CK nearly 100,000) that continuous renal replacement therapy (i.e., continuous dialysis), in addition to Calcium and shifting therapy, could not lower his K enough to prevent cardiac arrest (other futility complicated this picture) .  This was severe hyperkalemia.  There are no P-waves. The QRS is bizarrely wide.  In places, it looks nearly like a sine wave.  The last K was drawn 20 minutes before the ECG, and was 7.9 mEq/L.
