🔴ECG features of Torsades de Pointes
1. Change in amplitude (QRS) & twisting of the QRS comp. around the isoelectric line
2. Short-long-short pattern of R-R cycles (short-coupled PVC followed by a compensatory pause & then another PVC that falls close to Z peak of the T wave)

3.Usually shows a warm-up phenomenon
4. Frequently terminates spontaneously (in contrast to VF that does not terminate without defibrillation).
