Which statement is true about transcutaneous pacing readiness indications?

• A. For pacing readiness (standby mode) in MI with bradycardia
• B. Hemodynamically unstable tachycardia
• C. Ventricular fibrillation
• D. Atrial flutter

Answer: (A)

Transcutaneous pacing readiness focuses on being prepared to pace when a bradyarrhythmia threatens perfusion, especially during myocardial infarction where conduction can deteriorate. In the setting of an MI with bradycardia, the heart’s electrical signaling may be impaired, increasing the risk of progression to severe bradycardia or asystole. Having external pacing pads in standby allows rapid initiation of pacing if the rhythm slows or blocks, helping to maintain an adequate heart rate and perfusion while other treatments are pursued. The other scenarios describe rhythms where pacing isn’t the readiness indication: unstable tachycardia is typically treated with synchronized cardioversion; ventricular fibrillation requires immediate defibrillation; and atrial flutter is usually managed with rate or rhythm control rather than pacing readiness.
