The heart’s conduction system is more than physiology—it’s a living power grid that anesthesiologists interact with every time they induce, maintain, or recover a patient from anesthesia. In this episode of Cognitive Flow from OptimalAnesthesia.com, we break down the SA node, AV node, and Purkinje network using vivid analogies, clinical vignettes, and practical pearls. You’ll learn how anesthetic drugs, electrolytes, and perioperative stressors reshape the rhythm of the heart—and how to anticipate, detect, and manage conduction challenges safely in the OR.
