Polymorphic VT and Torsades de Pointes (TdP) • LITFL
Oct 8, 2024 · Polymorphic ventricular tachycardia (PVT) is a form of ventricular tachycardia in which there are multiple ventricular foci with the resultant QRS complex varying in amplitude, axis, and duration. The most common cause of PVT is myocardial ischaemia/infarction. Torsades de pointes (TdP) is a specific form of PVT occurring in the context of QT ...
Torsade de Pointes - StatPearls - NCBI Bookshelf
Aug 8, 2023 · Torsades de Pointes is a type of polymorphic ventricular tachycardia characterized by a gradual change in amplitude and twisting of the QRS complexes around an isoelectric line on the electrocardiogram. Torsades de Pointes is associated with QTc prolongation, which is the heart rate adjusted lengthening of the QT interval.
Torsades de Pointes: Symptoms, Causes and Treatment - Cleveland Clinic
Torsades de Pointes is a specific type of ventricular tachycardia, or fast heart rhythm that begins in your heart ventricles. You can get it if you inherited Long QT syndrome or if you take certain medicines.
Torsades de Pointes Ventricular Tachycardia
Torsades de pointes ventricular tachycardia 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 electrocardiogram (ECG) baseline.
Ventricular arrhythmias - EMCrit Project
Mar 19, 2023 · Torsade de pointes (TdP) is polymorphic ventricular tachycardia caused by an underlying prolongation of the QT interval (either congenital or acquired long QT interval). The vast majority of torsade results from acquired long-QT syndrome (due to electrolyte abnormalities and/or medications).
Torsades de Pointes Ventricular Tachycardia - MSD Manuals
Torsades de pointes ventricular tachycardia 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 electrocardiogram (ECG) baseline.
Torsades de Pointes Ventricular Tachycardia - Heart and ...
Ventricular tachycardia is a heart rhythm that originates in the ventricles (lower chambers of the heart) and produces a rapid heart rate. People with a long QT interval may develop a particular form of ventricular tachycardia called torsades de pointes ventricular tachycardia (torsades).

Understanding Torsades de Pointes Ventricular Tachycardia: …
Feb 15, 2024 · Torsades de Pointes Ventricular Tachycardia (TdP VT) is a potentially life-threatening heart rhythm disorder that can cause sudden cardiac arrest if not promptly treated. It is characterized by a specific type of ventricular tachycardia, where the heart's ventricles beat in a rapid and irregular manner.
