Task: Answer Verification
Input (English): Question: Does levosimendan improve cardiac output or blood pressure in a rodent model of propranolol toxicity when administered using various dosing regimens?
Answer: Unlike in verapamil and metoprolol poisoning models, levosimendan did not improve CO or survival in propranolol poisoning. Epinephrine improved BP, but not CO, suggesting that its actions were due to peripheral vasoconstriction.
Output (English): no
