Conclusion-
Acute cervical spinal cord injury is common and have important cardiovascular system consequences. Although very rare, still patients may develop polymorphic ventricular tachycardia, fibrillation and cardiac arrest. Critical care physician must be vigilant enough to recognise this form of tachycardia. Distinction between polymorphic VT with normal QT and polymorphic VT with QT prolongation is of paramount importance as treatment protocols differ. Autonomic imbalance along with loss of heart rate variability may be triggering factors in initiation of this arrythmia.
