Correct answer: D — Perform synchronised cardioversion now while continuing resuscitative support
Explanation lettering: E = shown as A · C = shown as B · D = shown as C · A = shown as D · B = shown as E
A is correct. Shock and altered consciousness make this unstable ventricular tachycardia, requiring immediate synchronised cardioversion. B may be considered only in stable, regular monomorphic broad-complex tachycardia when SVT with aberrancy remains possible. C delays definitive treatment. D can worsen shock and misreads AV dissociation. E is inappropriate for unstable VT.
