This represents a delay in the right bundle branch. This complex also follows a long - short interval (of sorts) and conducts with aberrancy. However, it probably fell in a part of the relative refractory period that was "more relative than refractory" and thus manifested only minor changes.<br /><br />Question: Were the six "wide complex beats" on the pre-hospital tracing themselves regular or irregular? If they were regular it could have been a short run of an AVNRT that began with an early beat and Ashman phenomenon followed by continuation of the aberrancy due to concealed transseptal conduction. If the short run was itself irregular, the Ashman phenomenon could only have accounted for the first aberrantly-conducted beat.<br /><br />Thanks for the great blog!<br /><br />Jerry W.
