This is a quiz. The ECG is pathognomonic. Answer is at the bottom.

























Hyperkalemia, with near sinusoidal pattern.  Note very wide QRS, bizarre deep T-waves in V1 and V2, peaked T-waves in V4 and V5, long PR interval this case.

Whenever you see a wide QRS, you must think of hyperkalemia.

The K was 8.7 mEq/L.  It responded to therapy.
