ECG findings associated with hypokalemia include:
A) U waves and flat T waves.
B) U waves and an Osborn wave.
C) an Osborn wave and a "J" wave.
D) flattened T waves and a widened QRS complex.

Question

Quizplus · Accepted Answer

Hypokalemia is associated with U waves, which are small, rounded waves occurring after the T wave and representing repolarization of the Purkinje fibers. It is also associated with flat T waves, which are caused by decreased intracellular potassium and delayed repolarization of the ventricles. An Osborn wave (also known as a J wave) is associated with hypothermia, not hypokalemia. A widened QRS complex is typically associated with conduction delays or other conduction abnormalities, rather than electrolyte imbalances.
