Can DKA cause ECG changes?

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.

Why do you need an EKG for DKA?

An ECG may reveal signs of acute myocardial infarction that could be painless in patients with diabetes, particularly in those with autonomic neuropathy. An ECG is also a rapid way to assess significant hypokalemia or hyperkalemia. T-wave changes may produce the first warning sign of disturbed serum potassium levels.

How does DKA affect the heart?

During DKA events, the myocardium is denied glucose uptake because of high levels of ketones and free fatty acids, leading to myocardial ischemia. This can further exacerbate the cardiovascular damage that has already occurred from acute MI.

Can DKA cause ST elevation?

Diabetic ketoacidosis (DKA) with resulting hyperkalemia can lead to ST-segment elevations on electrocardiogram (ECG). Previous publications theorize that significant improvements in patient potassium levels lead to the resolution of this rare phenomenon, also known as “pseudo-infarct” pattern.

Does DKA cause tachycardia?

Supraventricular tachycardia (SVT), however, is a very rare complication of DKA. We present the case of a patient with new-onset T1D who presented with DKA.

Can DKA cause heartburn?

What to know about diabetic gastroparesis. Gastroparesis affects how the stomach moves food into the intestines and leads to bloating, nausea, and heartburn. When diabetes causes the condition, doctors call it diabetic gastroparesis.

Why is Bun elevated in DKA?

Initial evaluation and monitoring of suspected diabetic ketoacidosis – BUN level is usually mildly to moderately elevated (mean 32 mg/dL) in diabetic ketoacidosis (DKA), attributable to significant volume loss rather than diabetic nephropathy.
