Elderly brought in due to altered mental status.

Image 1 - ECG case

What is the ECG saying?

This is a regular very wide QRS rhythm with no distinct P waves, peak T waves (noted from V3-V6 and II, III and aVF) and sine wave pattern or the disappearance in the delineation between the S and T waves. These are all indicative of hyperkalemia (K - 8). This patient had acute renal failure.
