When faced with a patient who is unresponsive to atropine and has persistent bradycardia, initiating transcutaneous pacing is the most appropriate treatment option. Transcutaneous pacing is a temporary measure that delivers electrical impulses to stimulate the heart when its intrinsic pacemaker fails to maintain an adequate heart rate, particularly in cases of symptomatic bradycardia. This method is critical in emergencies where a patient exhibits signs of hemodynamic instability, such as low blood pressure or altered mental status due to inadequate cardiac output.

Atropine is often the first line of treatment for bradycardia, but if it does not improve the heart rate or if the patient remains symptomatic, transcutaneous pacing provides a direct way to stabilize the patient's condition. It can help maintain an adequate heart rate while further evaluation and definitive treatment are arranged.

In this context, the other options are not appropriate. Administering aspirin is typically used for myocardial infarction or other thrombotic events but does not address the immediate issue of bradycardia. Performing a thoracotomy is an invasive procedure that is reserved for specific, critical situations such as cardiac arrest with a presumed cardiac cause or trauma and isn't indicated for isolated bradycardia.
