Final answer:
Ketamine can affect heart rate (HR) and blood pressure (BP) by blocking the Norepinephrine (NE) receptor. However, the impact on HR and BP can vary depending on factors like body temperature and electrolyte balance.
Step-by-step explanation:
Ketamine is a dissociative anesthetic that can affect heart rate (HR) and blood pressure (BP). It primarily works by blocking the Norepinephrine (NE) receptor, resulting in increased HR and BP. However, the impact on HR and BP can vary depending on other factors such as body temperature and electrolyte balance.
For example, slight hyperthermia can increase HR and strength of heart contractions, while hypothermia slows the rate and strength of heart contractions. Additionally, electrolyte imbalances like too high or too low sodium or potassium levels can also lead to abnormal HR and rhythm.
Therefore, the effects of ketamine on HR and BP can be complex and influenced by various factors.
