Ventricular tachycardia should be described by type (monomorphic or polymorphic), duration (sustained or non-sustained) and heart rate — i.e. monomorphic VT non-sustained at a heart rate of 220 ...

Monomorphic VT describes when your heart rhythm looks more steady from beat to beat when your doctor checks the electrical activity with an electrocardiogram (EKG). Polymorphic VT is a very ...

from single premature ventricular complexes to sustained monomorphic ventricular tachycardia (VT), polymorphic VT, and ventricular fibrillation. Sustained ventricular arrhythmias are the most ...

Patients with a severe form of ventricular arrhythmia who may be referred for catheter ablation are often first tested for coronary artery disease (CAD) or ischemia. But such testing seldom makes ...

The Purkinje-related ventricular arrhythmias range from isolated ectopies to monomorphic VT or polymorphic VT and VF, and occur in patients with or without structural heart disease (Table 2).

as was the incidence of monomorphic VT. The authors speculate that the higher incidence of polymorphic VT in the dofetilide patients could be explained by the possibility that the drug alters VT ...
