Typical ECG changes associated with hyperkalemia. → Peaked T wave → Wide PR interval, Wide QRS duration, Peaked T wave → Loss of P wave, Sinusoidal wave It is important to note that ECG changes may not correlate closely with serum potassium concentration or be useful in predicting outcomes. As such, a normal ECG should not necessarily be regarded as reassuring if elevated potassium concentration has been definitively observed. Such patients may still experience sudden hyperkalemic cardiac arrest episodes. #hyperkalemia #ECG #changes #progression #ekg #electrocardiogram #potassium
