A. Heart rate greater than 60/min B. Pedal pulses 2+ C. Pacer spikes after the QRS complex D. Distended jugular veins

Correct Answer is A

Explanation

- A: A heart rate greater than 60/min indicates that the transcutaneous pacing is effectively maintaining a heart rate within a normal range, which is crucial for adequate cardiac output and systemic perfusion.
- B: While 2+ pedal pulses indicate good peripheral perfusion, they do not directly reflect the effectiveness of transcutaneous pacing in treating complete heart block.
- C: Pacer spikes should appear before the QRS complex to show that the pacing stimulus is being delivered appropriately. Spikes after the QRS complex suggest that the pacing is not capturing the heart effectively.
- D: Distended jugular veins would be more indicative of heart failure or fluid overload and do not directly relate to the effectiveness of pacing therapy.
