Overview
- Variety of ventricular tachycardia resulting from prolongation of ventricular recovery time
- Polymorphic ventricular tachyarrhythmia with the appearance of slow polymorphic ventricular flutter without discernible QRS complexes or T waves; ventricular activity has constantly changing amplitudes & seems to revolve around the isoelectric line
- French term for “turning of the points” or turning of the directions of QRS complex alternatively between positive & negative
ECG Features
- Form of polymorphic ventricular tachycardia
- Rapid succession of ≥3 beats with a ventricular origin and rate >100 beats/min
- Noticeable change in the ventricular origin given the varying axis and morphology changes (“twisting of the points”)
