Wenckebach AV Block in Sinus Tachycardia
Report: Sinus tachycardia 106/min Right atrial abnormality (RAA) Second degree AV block, Möbitz 1 Up to 0.48” PR Intervals Junctional escape beat (third last QRS) LVH with ST/T changes Comment: The 4:3 and 5:4 Wenckebach cycles seen from beginning
Trigeminal Bradycardia
Report: Sinus tachycardia Advanced second degree AV block 9 second pause Junctional escape beats Comment: Some sinus beats are probably conducted, e.g., first two in the top strip. The long pause is terminated by a junctional escape (first beat in
Valsalva Manœuvre
Report: Top: Sinus rhythm & arrhythmia Blocked SVEB (first pause) Second degree AV block (second pause) Junctional escape beat Bottom: Sinus rhythm & arrhythmia First degree AV block Sinus arrest Comment: The vagal reflex triggered by the inspi
Post-Ectopic Sino-Atrial Depression
Report:Sinus rhythm 74/min SVEBs, one RBBB-aberrant Marked post-ectopic SA depression (overdrive suppression) Left bundle branch block Comment:The 7th beat’s P’ distorts the T wave of the preceding sinus beat. The pause containing the SVEB is more t
Junctional Escapes in Wenckebach Pauses
Report:Sinus rhythm Second degree AV block, Möbitz 1 Junctional escape beats Non-phasic aberrant conduction Comment:The ectopic complexes can be either premature or late (escape) beats. Here the Wenckebach pauses are interrupted by junctional escape
Sinoatrial Block: CVA
Report:Sinus rhythm Sinus pauses - probable Wenckebach exit block Junctional escape beats and rhythm Atrial fusion beats SVEB. Comment:The sinus cycles tend to shorten before the pause, a characteristic of Möbitz 1 (Wenckebach) exit block. There is
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 co
Echo (Reentry) Beats of Junctional Origin
Report: Top strip: Sinus bradycardia, progressive First degree AV block PR 0.24” Junctional escape beats Retrograde first degree AV block (RP 0.28”) Reentry (echo) beats of junctional origin Antegrade PR interval now 0.20” Incomplete RBBB Bottom
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 t
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
