Correct answer: C — Relatively fast HR 80-100 and low SVR

In severe AR: fast HR (80-100) shortens diastolic regurgitant time; low SVR promotes forward aortic flow. Bradycardia is dangerous (prolonged diastole massively increases regurgitant volume). Phenylephrine increases SVR worsening regurgitation. Goals are inverse of AS.
