WebHow does hypokalemia affect ECG? Electrocardiographic characteristics associated with hypokalemia include dynamic changes in T-wave morphology, ST-segment depression, and U waves, which are often best seen in the mid-precordial leads (V2V4). The PR interval can also be prolonged along with an increase in the amplitude of the P wave.
