HINT: It’s irregularly irregular with narrow complexes (which should give you the rhythm). Now what caused this cardiac arrest?

ANSWER: Yes! You should activate the cardiac cath lab. In fact, some argue that any patient resuscitated from VF should be sent to the lab regardless of what the 12-lead ECG shows. In this case we see atrial fibrillation with acute anterior STEMI. Cardiac cath showed 100% occlusion of the LAD. The patient was stented and therapeutic hypothermia was initiated.
