Which rhythm is depicted as a medical emergency on the EKG strip?

• A. Atrial flutter
• B. Ventricular defibrillation
• C. Sinus bradycardia
• D. Normal sinus rhythm

Answer: (B)

Ventricular defibrillation is depicted as a medical emergency on the EKG strip because it indicates a life-threatening condition where the heart is unable to effectively pump blood due to chaotic electrical activity in the ventricles. During ventricular defibrillation, the heart muscle quivers instead of contracting rhythmically, which results in a complete cessation of effective circulation. This arrhythmia requires immediate medical intervention, typically through the use of a defibrillator, to restore normal heart rhythm. In contrast, atrial flutter, while it can pose risks and lead to complications, is generally not as immediately life-threatening as ventricular defibrillation. Sinus bradycardia can also be concerning in certain contexts but may be asymptomatic and not require emergency treatment. Normal sinus rhythm reflects a healthy and effective heart rhythm, thus it does not represent an emergency situation.
