Hyperkalæmia

Report:

Sinus rhythm 89/min

Borderline first degree AV block

PR interval 0.20”

Right axis deviation +140o

Intraventricular conduction delay

QRS 0.13”

Peaked T waves c/c hyperkalæmia

Comment:

All the T waves (even the inverted ones) are peaked, but they are also characteristically narrow in V2-4. The potassium was 8.4 mEq/L.

The IVCD has general features of an LPHB. It resolved after hæmodialysis (Fig 28a). The ST/T changes reverted to their (known) baseline abnormalities.
