ECG diagnosis Bidirectional Ventricular Tachycardia

Journal of Cardiovascular Medicine and Cardiology
Abstract Bidirectional Ventricular Tachycardia (BVT) is a rare type of Ventricular Tachycardia (VT) and shows the beat-to-beat variation of the QRS axis and has high risk of sudden cardiac death. We present one such case, admitted during COVID epidemic.

Phenotypic variability in a series of four pediatric patients with Andersen-Tawil syndrome: A Saudi experience

International Journal of Pediatrics & Adolescent Medicine, 2019
Andersen-Tawil syndrome (ATS) is a rare genetic disorder characterized by periodic paralysis, ventricular arrhythmia, and dysmorphic features. However, the classical features are not always seen in the syndrome; therefore, the diagnosis can be ...
