A 57-year-old woman showed frequent premature ventricular complexes (PVCs) originating
from the right ventricular outflow tract (RVOT), and some of the PVCs triggered polymorphic …

We describe the case of a patient with long QT syndrome and recurrent ventricular
fibrillation, triggered by premature ventricular complexes (PVCs) with a left bundle branch …

Ventricular tachycardia originating from the right ventricular outflow tract (RVOT) is
considered benign, but sometimes it causes polymorphic ventricular tachycardia and …

Polymorphic ventricular tachycardia (PVT) is a life‐threatening arrhythmia that is typically
related to long QT syndrome, organic heart disease, electrolyte abnormalities, cardiotoxic …

A 6-year-old female with congenital long QT syndrome (LQTS) presented to the hospital with
recurrent syncope. She had frequent episodes of Torsade de pointes (TdP) that occurred at …

Congenital long QT syndrome (LQTS) is the most common inherited arrhythmia, fatal
arrhythmias are the main causes of sudden death, and often induced by the premature …

As our understanding of the mechanisms underlying the development of left ventricular (LV)
systolic dysfunction has evolved, there has been a greater appreciation of the heretofore …

Based on similarity of electrocardiographic features, bidirectional ventricular tachycardia has
been considered a variant of long QT syndrome. Genes causing long QT syndrome were …

Short QT syndrome (SQTS) is a very rare inherited arrhythmic disease that is associated with
sudden cardiac death (SCD) caused by ventricular tachyarrhythmias. Gussak and …

Background: The diagnosis of long QT syndrome (LQTS) is challenging when the QTc is
“borderline” and arrhythmias are not documented. Rationale: Since arrhythmias in the LQTS …
