Which of the following is not a feature of hyperkalemia on the ECG? a) Prolonged QT interval b) Tall peaked T waves c) Sine wave pattern d) Atrial

ECG in hyperkalemia In this ECG some features due to hyperkalemia are visible: Tall T waves – T waves in anterior leads are as tall as or taller

Tall peaked T waves Tall peaked T waves are seen in leads V2-V4 (C2-C4). In addition there is prominent negative component for P wave in lead V1 (C1)

QT interval is not increased with: a) Acidosis b) Hyperkalemia c) Hypercalcemia d) Digoxin e) All of the above f) None of the above

Cardiotoxic effect of hyperkalemia increased by: a) Hypernatremia b) Hypercalcemia c) Hypocalcemia d) Alkalosis

All of the following are seen in hyperkalemia except: a) PR prolongation b) Tall tented T waves c) Diminished P wave amplitude d) Narrow QRS complex
