Final answer:
The question is asking about the signs/symptoms and treatment for beta-blocker toxicity, which includes symptoms such as bradycardia and hypotension, and can be treated with atropine, glucagon, or other supportive measures.
Step-by-step explanation:
The question appears to be asking for the signs and symptoms (s/s) and treatment (tx) of BB toxicity, which likely refers to beta-blocker toxicity. Beta-blockers are medications that are commonly used to treat high blood pressure, heart rhythm problems, and a variety of other cardiovascular conditions.
Signs and symptoms of beta-blocker toxicity can include bradycardia (slow heart rate), hypotension (low blood pressure), heart block, dizziness, lethargy, and in severe cases, cardiac arrest. Treatment may involve a variety of steps including supportive care with intravenous fluids, administration of atropine to increase heart rate, and in some cases, use of specific antidotes such as glucagon, which can help to increase heart rate and blood pressure. Additional measures might include the use of high-dose insulin euglycemia therapy, vasopressors, or intralipid therapy, depending on the severity of the toxicity and the clinical presentation of the patient.
