Taking a Pause to Consider Arrhythmic Etiologies of Syncopes. A significant pause from sinus node dysfunction led to infrequent episodes of syncope. The patient’s past medical and family history allow us to discuss a broad differential diagnosis for syncope, and consider diagnostic testing that may help elucidate the cause.

G. Conte,C. H. Moog,A. M. Perdonterfascicular reentrant VT. We present a case of VT storm due to interfascicular reentrant VT of two distinct, paired morphologies. One utilized the left posterior fascicle for anterograde conduction and the other utilized the left posterior fascicle for retrograde conduction.

G. Conte,C. H. Moog,A. M. Perdonno response to adenosine. He was taken to the electrophysiology lab with high suspicion for ventricular tachycardia. Electroanatomic mapping demonstrated the arrhythmia to be a roof-dependent left atrial flutter, which was successfully terminated with radiofrequency ablation.

G. Conte,C. H. Moog,A. M. Perdoncase highlights limitations in current diagnostic criteria for arrhythmogenic right ventricular cardiomyopathy (ARVC), as well as the potential benefit in selected patients of voltage-map guided biopsy to further guide treatment and prognosis.

G. Conte,C. H. Moog,A. M. Perdond recognition of torsades de pointes, and with cessation of dofetilide, her episodes of presyncope resolved. In the right context, as in use of a QT prolonging drug, acquired long QT syndrome and torsades de pointes may be an etiology of presyncope or syncope.
