Which scenario is a typical indication for transcutaneous pacing?

• A. Normal sinus rhythm
• B. Mild dizziness
• C. Tachycardia with narrow complex
• D. Bradycardia unresponsive to drugs

Answer: (D)

Transcutaneous pacing is used as a temporary, noninvasive way to deliver external electrical impulses to the heart when the rhythm is too slow and is causing poor perfusion or instability. The scenario fits best when a patient has bradycardia that remains unresponsive to drug therapy, because medications that raise heart rate (like atropine or temporary pressors) have not succeeded, yet the patient still needs a rapid, reliable heart rate to maintain blood flow. In this situation, pacing pads are placed on the chest, a pacing rate is set, and energy levels are adjusted to ensure an adequate heart rate until a more permanent solution (like transvenous pacing) can be established. Normal sinus rhythm wouldn’t require pacing, mild dizziness alone isn’t specific enough to justify pacing, and tachycardia with a narrow complex is the opposite issue—pacing isn’t used to speed up a heart that’s already too fast.
