A patient with severe uncontrolled cardiac arrhythmia would be classified as which ASA grade?

Explanation:
This tests understanding of the ASA physical status classification used before anesthesia. The key is how life-threatening the systemic condition is. An ASA IV label is for severe systemic disease that is a constant threat to life. A severe, uncontrolled cardiac arrhythmia fits this description because it represents ongoing, life-threatening instability that can deteriorate at any moment. Therefore, it best matches ASA IV. It isn’t ASA V, which would be a moribund patient not expected to survive without the operation, since that level implies imminent death regardless of intervention.
