Electrocardiogram
- Nonspecific ECG changes including sinus tachycardia, st segment changes, and changes in heart rate variability; which can be seen in long-standing diabetes mellitus may also be present during an episode of hyperosmolar hyperglycemic state.
- ECG findings associated with hyperkalemia seen during hyperosmolar hyperglycemic state include:[1]_Circulation-2|[2][3][4]
- Tall peaking T waves
- Prolonged QT interval
- Widening of QRS complex
- Prolongation of the ST interval
