658 Ventricular Tachycardia vs. Junctional Tachycardia, <strong>rate</strong> 138<br />
Ventriculo-<strong>atrial</strong> Conduction 1:1<br />
Note: The cause of this wide complex tachycardia with a RBBB configuration was confirmed<br />
by recording <strong>atrial</strong> potentials from an esophageal lead (see 660) that confirmed 1:1 V-A<br />
conduction and that the notches in the initial portion of the T waves were P waves.<br />
658: This wide complex tachycardia was well tole<strong>rate</strong>d by the patient, providing an opportunity<br />
to establish its origin. The Ladder indicates 1:1 VA conduction confirmed by esophageal lead<br />
electrogram in 659. One-to-one V-A conduction could have resulted from either a junctional or<br />
ventricular tachycardia.
