As a medical professional with expertise in cardiology, I can tell you that Torsades de Pointes is a specific type of arrhythmia, which is a heart rhythm disturbance. It is characterized by rapid and irregular heartbeats that can be life-threatening. The term "Torsades de Pointes" translates to "twisting of the points," which is a visual description of the pattern seen on an electrocardiogram (ECG) during this arrhythmia.
Torsades de Pointes is a polymorphic ventricular tachycardia, which means it involves multiple, irregular ventricular contractions. It is often associated with a prolonged QT interval on the ECG, which is a measure of the time between the start of the Q wave and the end of the T wave. A prolonged QT interval can be congenital (inherited) or acquired due to certain medications or electrolyte imbalances.
The condition is potentially dangerous because it can lead to a complete loss of consciousness (syncope) and even sudden death if not treated promptly. Treatment typically involves correcting the underlying cause, such as adjusting medications or addressing electrolyte imbalances, and may include the use of antiarrhythmic medications or a procedure to reset the heart's rhythm.

Torsades de pointes is a specific form of polymorphic ventricular tachycardia in patients with a long QT interval. It is characterized by rapid, irregular QRS complexes, which appear to be twisting around the ECG baseline. This arrhythmia may cease spontaneously or degenerate into ventricular fibrillation.read more >>
