Cardiovascular disturbances are the leading causes of morbidity and mortality in patients of spinal cord particularly cervical cord injury accounting for approximately 30% of deaths. Most common cardiovascular dysfunctions are sinus bradycardia, hypotension, cardiac arrest, supraventricular tachycardia and all these occurs due to sympathetic withdrawal and unopposed vagal action. Here we are reporting a case of acute cervical cord injury with neurogenic shock in a 25 year young patient who developed polymorphic ventricular tachycardia, which degenerated to ventricular fibrillation and cardiac arrest. We described all possible mechanisms of development this arrythmia and its management.
