In brief: Electrolytes

Hyperkalemia can caus several ECG abnormalities.
First one may see "peaked t waves". Ventricular ectopic beats (pvc's) as well as tachycardia may develop. If untreated the rate can slow and a "sine wave pattern" which is a wide slow wave form that is a pre-terminal rhythm. Hyper kalmia is a medical emergency that needs to be treated rapidly.
