Polymorphic VT and Torsades de Pointes (TdP) • LITFLPolymorphic VT and Pointes Torsades (TdP)Polymorpha ventricular tachycardia (PVT) is a form of ventricular tachycardia in which there are multiple ventricular foci with the resulting QRS complexes that vary in amplitude, axis and duration. The most common cause of PVT is myocardial ischaemia. Point Torsades (TdP) is a specific form of polymorphic ventricular tachycardia that occurs in the context of QT prolongation; it has a characteristic morphology in which the complex QRS "twist" around the isoelectric line. For TdP diagnosis, the patient must have evidence of PVT and QT prolongation. is another type of polymorphic VT, more commonly associated with digoxin toxicity. New review of the examples of the Pointes Torsades Group of Experts:TdP secondary to hypokalaemia:TdP secondary to hypokalaemia: Pointes Torsades:NB. See how the blood pressure wave (lower tracing) is affected by dyshythmia. There is a reduced volume pulse during the first PVC as the heart has less time to fill. Then the cardiac output collapses to almost nothing during the TdP career – this is likely to result in syncope or cardiac arrest.

Advert Ventricular and point torsades volume 4, pages1177–1182(1990) Volume 4130 Accesses7 Citations Conclusions We have tried to give a general description of the traces of the ECG (obtained from, patients during cardiac resuscitation) that show progressive variations in the amplitude, and we have tried to develop a new set of diagnostic criteria. Two different arrhythmias were defined: Ventricular Fibrillation. This starts very soon after the previous ventricular complex, it appears as continuous oscillations that seem like a fine tremor (frequency in cycles per second range) and a amplitude that gradually varies to form lumps. We have no example of ventricular fibrillation that spontaneously reverts in normothermic conditions. Pointer screws. This is always initiated by a "specific electrical complex" and continues with progressive, regular and successive investments of the stroke (with a frequency in cycles per minute) and ends spontaneously after a ventricular pause. There are also two intermediate patterns: Double peaks. This arrhythmia, which occurs during long episodes of point torsades, has a slower frequency than the episodes of ventricular fibrillation that occur during hypothermia (an experimental condition that was used to allow the study of spontaneous termination of ventricular fibrillation). The anarchical interlude of long episodes of spontaneously reversible torsades.
