Overview[edit | edit source]

There are no abnormal ECG findings associated with gastroparesis. In case of malnutrition and electrolyte imbalance, an ECG may be helpful. Hypokalemia might present with arrhythmia, ST segment depression, low T wave, prominent U waves and QRS prolongation. Hypocalcemia might present with QT interval prolongation.
