Cardiac arrest: The Daily PANCE Blueprint

A 55-year-old woman presents to the emergency department with severe substernal chest pain radiating to her left arm. She has a history of hypertension and hyperlipidemia. Her ECG shows an anterior wall ST-segment elevation myocardial infarction. She is given 325 mg of aspirin, and oxygen is administered. An IV is started, but shortly thereafter, the patient loses consciousness. The cardiac monitor displays a disorganized, non-perfusing ventricular rhythm. What is the most important initial treatment for this patient?

A. Administer intravenous epinephrine
B. Start chest compressions immediately
C. Perform synchronized cardioversion
D. Administer intravenous amiodarone
E. Provide supplemental oxygen via mask

Answer and topic summary

The answer is B. Start chest compressions immediately

The most important initial treatment for a patient who becomes unresponsive with a disorganized, non-perfusing ventricular rhythm (likely ventricular fibrillation or pulseless ventricular tachycardia) is to start chest compressions immediately. Early initiation of chest compressions is critical for maintaining circulation and increasing the chances of survival and favorable neurological outcomes. This is followed by defibrillation as soon as possible.
