Ventricular tachycardia of right bundle-branch block--left axis deviation morphology and organic heart disease.

Upper septal transformation of verapamil-sensitive idiopathic left ventricular tachycardia during catheter ablation: Wolf in sheep׳s clothing?☆

Introduction Verapamil-sensitive fascicular ventricular tachycardia (VT) is the commonest form of idiopathic left ventricular tachycardia (ILVT). The characteristic diagnostic features of fascicular ILVT include: (i) induction with atrial pacing, (ii) right bundle branch block (RBBB) with left-axis deviation morphology during VT, (iii) absence of structural heart disease, and (iv) verapamil sen...

ECG of the month. Idiopathic ventricular tachycardia with a left bundle branch block morphology and right axis deviation.

PATHOPHYSIOLOGY AND NATURAL HISTORY VENTRICULAR ARRHYTHMIA Idiopathic sustained left ventricular tachycardia: clinical and electrophysiologic characteristics

Electrophysiologic studies were performed in 16 patients 11 to 45 years old (mean 33 years) with idiopathic sustained (lasting more than 5 min) ventricular tachycardia (VT) originating from the left ventricle. Endocardial mapping during VT showed that the earliest site of activation was at the apical inferior portion of the left ventricle in 14 patients whose QRS morphology during VT showed a r...

The risk of advanced heart block in surgical patients with right bundle branch block and left axis deviation.

The risk of advanced atrioventricular block during anesthesia was studied prosepctively in 44 patients with right bundle branch block and left axis deviation who underwent a total of 52 operations over a 14 month period. All patients had continuous electrocardiographic monitoring throughout anesthesia induction, operation, and surgical recovery. Of the 52 operative procedures, 24 were done unde...
