Overview
Patients suffering from diabetic ketoacidosis (DKA) may exhibit electrocardiographic (EKG) changes characteristic of toxic hyperkalemia and hypocalcemia. Common abnormalities observed on EKG include tall peaking T waves, prolonged QT interval and widening of QRS complex.
Electrocardiogram
- Electrocardiogram (ECG or EKG) abnormalities characteristic of toxic hyperkalemia and hypocalcemia.[1]
- The following EKG findings may be observed in diabetic ketoacidosis (DKA):[2][3][4][5]
- Tall peaking T waves
- Prolonged QT interval
- Widening of QRS complex
- Prolongation of the ST interval
- ST segment elevation
