Polymorphic Ventricular Tachycardia in Acute Cervical Spinal Cord Injury: A Rare Occurrence in the Setting of Normal QTc.

Cardiovascular manifestations like bradycardia, hypotension, fluctuation of blood pressure, and supraventricular arrhythmia are common in acute spinal cervical injury above the C6 level and are the major cause of mortality and morbidity in them. Ventricular tachycardia (VT) and fibrillation have only been reported in a few cases, but polymorphic VT (PMVT) has not been reported. We report a very rare case of acute cervical spinal cord injury patient who developed PMVT in the setting of normal QT interval degenerating to ventricular fibrillation, causing cardiac arrest before surgery.
