Escape-Capture Bigeminy
Report: Sinus rhythm 92/min Second degree AV block, probably 2:1[!xe "AV block:second degree:2-1" \b!] Junctional escape beats[!xe "Junctional escape beats:second degree AV block" \b!] Escape-capture bigeminy Non-phasic aberration[!xe "Aberrant conduc
Echo (Reentry) Beats of Junctional Origin
Report: Top strip: Sinus bradycardia, progressive First degree AV block PR 0.24â Junctional escape beats Retrograde first degree AV block (RP 0.28â) Reentry (echo) beats of junctional origin Antegrade PR interval now 0.20â Incomplete RBBB B
Not a Sinus Bradycardia
Report: Sinus rhythm Sinus arrest Junctional escape beats Retrograde conduction Non-phasic aberrant conduction Escape-capture bigeminy Comment: The phenomenon of escape-capture bigeminy depends on the coincidental arithmetic relationship between the
Sinus Bradycardia: Escape-Capture Bigeminy
Report:Sinus bradycardia 34 - 43/min Junctional escape beats Escape-capture bigeminy Phasic aberrant conduction, RBBB type Comment: The mechanism of the bigeminy is sinus bradycardia. Here the effective sinus cycle is the same as the actual one; in ot
Sino-Atrial Exit Block
Report:Sinus rhythm 74/min 3:2 sino-atrial exit block Bigeminy Negative U waves in lead 1 Comment:The same comments can be made here as for the preceding Case 93. It, too, could have Möbitz 2 mechanism. Below (Fig 94a) is another trace, with long cy
Onset of Retrograde Conduction
Report:Top: Sinus tachycardia 104/min VEB Monomorphic ventricular tachycardia 152/min Retrograde conduction Bottom: Sinus tachycardia 110/min Fusion VEBs in bigeminy Monomorphic ventricular tachycardia 150/min Retrograde conduction Comment:In bo
