Torsades de Pointes Ventricular Tachycardia
Symptoms and Signs of Torsades de Pointes Ventricular Tachycardia
TdeP VT often causes syncope because the underlying rate (200 to 250 beats/minute) is nonperfusing. Palpitations are common among conscious patients. Because the QT interval shortens with increased ventricular rates TdeP VT is often self-terminating. However, it instead may degenerate into Ventricular Fibrillation (VF) and cause sudden death. Sometimes the long QT interval is detected after resuscitation.
