Cold Shock

Medulla - Nucleus Tractus Solitarius - Parasympathetic/Sympathetic Nerves

Parasympathetic (Vagus): Decreases Heart Rate 

Sympathetic (Thoracic Spinal Cord): Increases Heart Rate 

Baaroreceptor Reflex In Heart: Sensing Changes 

Arterial Pressure Increase = Decrease Heart Rate and Myocardial Contractility

Increased Arterial Pressure Leads To Bradycardia

Bradycardia Is Dangerous

Eg: Cold Water Induced Cardiac Arrest

Immersion Syndrome
