Tag: sine wave pattern

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 in hyperkalemia is due to the enhanced outward potassium current IKr. QRS widening is due to the reduced Vmax as the intracellular negativity

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
