A young lady was found unconscious by her parents while she was exercising. She was rushed to emergency medicine depament where her blood sugar levels were repoed to be 250 mg/dl. No history of diabetes was there. ABG analysis was suggestive of metabolic acidosis. Thus, diagnosis of DKA was made. The patient was managed and gradually she improved as well. Her ECG is given below. Where is the pathology likely located in hea of the patient in above clinical scenario?

💡 Explanation
**Core Concept**
Diabetic Ketoacidosis (DKA) is a metabolic state characterized by hyperglycemia, metabolic acidosis, and ketosis. In DKA, the body produces high levels of ketones, which can lead to cardiac complications.
**Why the Correct Answer is Right**
The ECG changes in DKA are often attributed to the effects of potassium depletion and acidosis on the myocardium. The patient's metabolic acidosis can lead to a decrease in potassium levels, causing cardiac membrane instability. Additionally, the high levels of ketones can have a direct toxic effect on the myocardium. The ECG changes may include ST-segment depression, T-wave flattening, and QT interval prolongation.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect as it does not specify the location of the pathology in the heart.
* **Option B:** This option is incorrect as it does not relate to the clinical scenario of DKA.
* **Option C:** This option is incorrect as it does not provide a plausible explanation for the ECG changes in DKA.
**Clinical Pearl / High-Yield Fact**
In DKA, the cardiac membrane instability can lead to arrhythmias, including ventricular fibrillation. Early recognition and management of DKA are crucial to prevent cardiac complications.
**Correct Answer: C.** **Correct Answer:** C. **The pathology is likely located in the Purkinje fibers of the heart.**
