AVNRT Slow/Slow

Associate Editor-In-Chief:


 * Main article: AVNRT

Characteristics

 * 1) Dual AV Nodal Physiology and jump with initiation
 * 2) Retrograde VA > 60 ms
 * 3) AH > HA
 * 4) Earliest Atrial Activation in posterior septal region

Diferentiation of AVNRT Slow/Slow from AVRT with AVRT using a Concealed Bypass Tract

 * P wave morphology
 * Negative in the Inferior Leads in both
 * Positive in AVNRT Slow/Slow and Positive or biphasic in AVRT using a Posterior Septal Concealed Bypass Tract
 * Delta RP (V1-II) > 25 ms
 * Delta RP (V1-III) > 23 ms
 * Delta RP (V1 - aVF) > 30ms
