In this episode of Optimal Anesthesia Insights, we explore the parasympathetic nervous system (PNS) and its critical role in cardiac regulation. From the vagus nerve's impact on heart rate to the molecular mechanisms of M₂ receptors, cAMP, and GIRK channels, we break it down in a way that’s clinically relevant and easy to understand.

Why does laryngoscopy, spinal anesthesia, or vagal stimulation lead to severe bradycardia? How do atropine and dexmedetomidine influence vagal tone? We answer these key anesthesia-related questions and more.
