Which rhythm is considered a non-shockable rhythm?

• A. Ventricular Tachycardia (VT)
• B. Ventricular Fibrillation (VF)
• C. Asystole
• D. Normal sinus rhythm

Answer: (C)

Asystole is indeed considered a non-shockable rhythm in the context of cardiac arrest management. This is a state where there is no electrical activity in the heart, meaning there are no contractions occurring; it appears as a flatline on the ECG. Since there is no organized electrical activity or pulse, defibrillation will not be effective in restoring a normal rhythm, which is why immediate cardiopulmonary resuscitation (CPR) and advanced life support measures are prioritized instead. In contrast, both Ventricular Tachycardia (VT) and Ventricular Fibrillation (VF) are shockable rhythms. In these cases, there is disorganized electrical activity in the heart, and electrical intervention, such as defibrillation, can potentially restore a viable rhythm. Normal sinus rhythm is considered a stable, functioning rhythm and does not require immediate intervention, distinguishing it clearly from non-shockable states like asystole.
