What did the ECG show after attaching the patient to the monitor?

• A. Atrial fibrillation with rapid rate
• B. Ventricular tachycardia
• C. Normal sinus rhythm with no ectopy
• D. Asystole

Answer: (C)

The main idea here is recognizing a normal, stable heart rhythm on the ECG. Normal sinus rhythm means the heart’s electrical impulse starts in the sinoatrial node and travels in a regular pattern, so you see a P wave before every QRS complex, with a consistent PR interval and a narrow QRS. “No ectopy” means there are no premature or ectopic beats coming from the atria or ventricles. This is the best fit because it shows the heart is conducting normally without abnormal rhythms. If the ECG showed atrial fibrillation, you’d see an irregular rhythm with no distinct P waves. If it showed ventricular tachycardia, you’d have a fast, wide-complex rhythm. If it showed asystole, the tracing would be a flat line with no electrical activity.
