A sailor's dilemma: A case of preexcitation via a fasciculoventricular pathway Nicholas J. Rohrhoff, MD, LT, MC (UMO/DMO), USN, Huckelberry A. Finne, MD, LCDR, MC (UMO/DMO), USN, Yasser Rodriguez, MD, MBA HeartRhythm Case Reports Volume 3, Issue 7, Pages 364-367 (July 2017) DOI: 10.1016/j.hrcr.2017.05.013 Copyright © 2017 Terms and Conditions

Figure 1 Patient's 12-lead surface electrocardiogram. Sinus rhythm at 75 beats per minute, PR interval of 128 ms, QRS interval of 98 ms, and QTc interval of 411 ms. Evidence of preexcitation demonstrated by slurred QRS upstroke (delta wave) in leads V4-V6.

Figure 2 Intracardiac tracing during atrial pacing at 500 msec during adenosine infusion in a similar case.14 FVP is identified by prolongation of the AH interval and constant degree of preexcitation with fixed H-V interval. When AV node is blocked, block occurs in accessory pathway simultaneously.
