Abstract/OtherAbstract:
An electrocardiogram was obtained that was characterized by sinus rhythm with progressive prolongation of the PR interval not followed by a blocked sinus impulse. After a critically long PR interval, the QRS complex was followed by a premature P' wave, representing an echo beat, a manifest reentry in the atrioventricular (AV) node. The pause, occasioned by the premature P' wave, was at times interrupted by an AV junctional escape beat, occurring with an escape interval of 1.21-1.24 seconds. On other occasions, however, the escape beat did not manifest on schedule, even though the pause was markedly longer than the escape cycle. This suggested that the manifest reentry was followed by a further concealed reentry, resulting in inapparent discharge of the AV junctional escape pacemaker, whose firing was postponed, thereby allowing the sinus impulse to capture the ventricles.
