Sep 7, 2021 · Polymorphic VT with unique ECG characteristics may strike in patients with coronary artery disease in the absence of acute ischemia. 110–112 Arrhythmic storms tend to occur within days of an acute myocardial infarction or coronary revascularization procedure, 110,112 but similar arrhythmias have been described in patients presenting with syncope or out-of-hospital cardiac arrest. 111,112 ...

Feb 15, 2024 · Polymorphic ventricular tachycardia. This type of VT is a very dangerous type of arrhythmia. The “poly” part means your heart’s electrical activity is all over the place.
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.
The long QT syndrome (congenital or acquired) is associated with a particular form of VT, torsades de pointes. Ventricular tachycardia may be monomorphic or polymorphic and nonsustained or sustained. Monomorphic VT: Single abnormal focus or reentrant pathway and thus regular, identical-appearing QRS complexes
Oct 24, 2024 · Catecholaminergic Polymorphic Ventricular Tachycardia: A rare, genetic condition triggered by physical activity or stress. It is an example of polymorphic ventricular tachycardia and requires careful ventricular tachycardia management. Causes of Ventricular Tachycardia: Coronary Artery Disease. VT can develop due to a wide range of underlying ...

VT ventricular tachycardia Figure 1. Approach to the patient with polymorphic VT. After excluding mimicries of polymorphic VT, the first question is whether the patient has a long QT syndrome (not merely a long QT interval [see section on “pseudo–torsade de pointes”]); the second question is whether the patient has organic heart disease.
