Question

SCD is defined as an episode of which of the following?

1. Ventricular fibrillation
2. Pulseless ventricular tachycardia
3. Pulseless electrical activity
4. Asystole
A. 1 and 2
B. 2 and 3
C. 1, 2 and 3
D. 1, 2 3, and 4

Answer 1

SCD is defined as an episode that includes ventricular fibrillation, pulseless ventricular tachycardia, pulseless electrical activity, and asystole. The answer to the question is D. All these states require urgent medical action.

Step-by-step explanation:

SCD, or sudden cardiac death, is defined as an episode including ventricular fibrillation, pulseless ventricular tachycardia, pulseless electrical activity, and asystole. Therefore, the correct answer to the question is D. 1, 2, 3, and 4. These conditions represent severe disruptions in the electrical activity of the heart. Ventricular fibrillation and pulseless ventricular tachycardia are emergencies that require immediate life support such as defibrillation, which delivers a shock to establish a normal sinus rhythm. Pulseless electrical activity and asystole are also critical states where the heart exhibits no effective contraction or electrical activity, respectively, demanding immediate medical intervention.
