VEBs: Concealed Retrograde Conduction
Report: Sinus rhythm Left atrial abnormality VEBs, uniform; couplets[!xe "VEBs:concealed conduction:couplets" \b \i!][!xe "VEBs:couplets" \b \i!] Concealed retrograde conduction Comment: Despite a slight sinus arrhythmia it is possible to map out un
Sinus Captures in Nodal Rhythm
Report: Junctional rhythm 42/min Sinus capture beats AV dissociation with interference Concealed conduction Comment: The sinus captures are only possible after sufficient distance from the preceding QRS complex has rendered the AV node amenable to con
Sustained Concealed Conduction on Holter Monitor
Report:Sinus rhythm 60 â 70/min Borderline first degree AV block Second degree AV block, Wenckebach (Möbitz 1) type VEB, interpolated Concealed retrograde conduction in three subsequent cycles Comment:Sustained PR interval prolongation after an in

VEBs: Trigeminy & Trigeminy
Report:Sinus arrhythmia Left atrial abnormality (LAA) First degree AV block Atrial ectopic beat (second P wave in the bottom strip) VEBs in trigeminy Concealed retrograde conduction Comment:In the top strip, every third P wave is blocked by a VEB. I
Far-Reaching Interpolation
Report:Sinus rhythm. VEBs, 2 interpolated. Comment:The concealed retrograde conduction governing the PR interval after an intercalated VEB rarely affects more than one cycle. In the top and middle strips, the first VEB is intercalated and prolongs the
Interpolated VEBs & Couplets
Report:Sinus rhythm VEBs, some interpolated, some (bottom strip) in couplets (pairs) Comment:In the top strip, the first VEB blocks the ensuing sinus P wave, creating a fully compensatory pause. The other two penetrate the AV junction retrogradely (conc
Two for the Price of One
Report: Sinus rhythm 80/min (top) & 91/min (bottom) VEBs, two couplets Fully compensatory pauses (top) Comment: Depending on the sinus rate and the timing of the VEBs, a couplet may replace one or two sinus beats; usually it replaces two, as in the bot
