This is a sinus tachycardia. The P waves are negative ... This is a case of left posterior fascicular block. Note the beat-to-beat changes in the QRS complex amplitude (*, ^); these are known ...

Initially, clinicians suspected that the patient had supraventricular tachycardia with RBBB and left anterior fascicular block aberrancy. However, upon further assessment of leads II and V1 ...

During SARS-CoV-2 pauci-symptomatic infection, a child and an adolescent with congenital heart disease (CHD) along with a pacemaker reported fascicular tachycardia and atrial flutter, respectively.

However, the patient is older than is typical for presentation with fascicular ventricular tachycardia, which usually manifests in patients 15 to 40 years of age. The width of her QRS complex in ...

Left posterior fascicular ventricular tachycardia (LPFVT) is extremely rare in neonates. We described a 17-day-old girl with LPFVT who was initially misdiagnosed as supraventricular tachycardia (SVT).

The correct diagnosis is sinus tachycardia, left atrial abnormality, and QRS (electrical) alternans, right axis caused by left posterior fascicular block (Figure 2). The rhythm is regular at a ...

and fascicular ventricular tachycardia (which also originates from the conduction system). Both these entities can be readily identified during the electrophysiological study and treated with ...

The most common form of idiopathic Purkinje-related ventricular tachycardia (VT) is the reentrant type. We describe the clinical and electrophysiological characteristics of focal non-reentrant ...
