Hypokalemia: serum potassium levels below 3 mEq/L causes progressive depression of the ST-segment, a decrease in T wave amplitude, and an increase in U wave amplitude (read hypokalemia). … WebT-wave inversion may occur in severe hypokalemia. ST segment depression develops and may, along with T-wave inversions, simulate ischemia. P-wave amplitude, P-wave duration and PR interval may all increase. Finally, U-waves emerge. U-waves are best seen in leads V2–V3. If the hypokalemia is severe, the U-wave may become larger than the T-wave.
