Torsade de Pointes tachycardia is a type of ventricular tachycardia. It is characterized by rapid, irregular QRS complexes, which appear to be twisting around the baseline of the ECG.
Most common diseases
Tonsillitis
Torsades de pointes is associated with a prolonged QT interval, which may be congenital or acquired.[1, 2] Torsades de pointes is usually not sustained and terminates spontaneously [patient.info]
Torsades de Pointes is triggered by a PVC occurring on a preceding T wave. The onset of Torsades de Pointes is often preceded by a run of short-long-short R-R intervals. [ncbi.nlm.nih.gov]
Most cases of torsades de pointes resolve on their own without treatment. [medicalnewstoday.com]
Cardiac Arrhythmia
The authors report the cases of three patients who developed torsades de pointes arrhythmia or lengthening of the Q-T interval during treatment with intravenous haloperidol [ncbi.nlm.nih.gov]
During the arrest and over the subsequent 48 hours, malignant tachyarrhythmias were manifested by torsade de pointe and repeated episodes of ventricular fibrillation. [ncbi.nlm.nih.gov]

Sinus Bradycardia
Symptoms included syncope (n 2), torsades de pointes (n 7), and hemodynamic failure (n 6). Three infants with 2:1 AVB died during the first month of life. [ncbi.nlm.nih.gov]

Hypokalemia
In addition, it reiterates the importance of repeated history taking in a patient with undiagnosed hypokalemia and torsade de pointes which avoided a device therapy. [ncbi.nlm.nih.gov]
BACKGROUND: Our primary objective was to determine the adjusted quantitative associations of clinical predictors with QT prolongation, a defining cause of Torsades de Pointes [ncbi.nlm.nih.gov]

Torsades De Pointes
Torsades de pointes is associated with a prolonged QT interval, which may be congenital or acquired. [ 1, 2 ] Torsades de pointes is usually not sustained and terminates spontaneously [patient.info]
Drug-induced torsades de pointes is known to majorly strike the female population. Cause: Torsades de pointes can either be acquired or congenital in nature. [symptoma.com]
Therefore, torsades de pointes is more common in white races and in females. [ 4 ] Torsades occurs at any age. [patient.info]
Ventricular Tachycardia

Ventricular tachycardias include ventricular tachycardia, ventricular fibrillation, and torsades de pointes; although these rhythms may be benign and asymptomatic, others [ncbi.nlm.nih.gov]
