Another RVOT VT: Retrograde 1:1 Conduction
Report:Ventricular tachycardia 168/min Comment:This is a good example where conduction sequences and QRS morphology do not help in making the diagnosis. Each QRS is followed after 0.18â by a sharp upright P wave in V1 consistent with a retrograde P wav
Pentageminy!
Report: Sinus rhythm Left atrial abnormality (LAA) Intraventricular conduction delay, probably incomplete LBBB (QRS 0.12â) VEB triplets (VT 220/min) in pentageminy Comment: An allorhythmia is a repetitive pattern of a combination of beats. Pentagemi
R-on-P Bigeminy
Report:Sinus rhythm 93/min First degree AV block (PR 0.28â) VEBs, bigeminal Early transition (counterclockwise rotation) Nonspecific ST/T changes Comment:The VEBs are easily recognised for what they are, with obvious dissociation from the preceding
R-on-T & R-on-P at the Same Time
Report: Sinus tachycardia 124/min VEBs in bigeminy & trigeminy R-on-T phenomenon Right bundle branch block Comment: The bigeminal VEBs would be still narrower were it not for the superimposition of sinus P waves on their initial vector. The VEBs not
Good Torsade, Wrong Components
Report: Sinus tachycardia 112/min Left bundle branch block Ventricular tachycardia 118/min Ventricular fusion beats Probable 1:1 retrograde conduction Junctional escape beats (bottom) Comment: The two panels are almost identical and one has to compa
Junctional Rhythm: Fusion Trigeminy
Report: Junctional rhythm 65/min Left bundle branch block VEBs in trigeminy, late-diastolic Ventricular fusion beats Comment: The junctional focus appears protected from the VEBs; the pauses are fully compensatory. The morphology of the junctional bea
VF: R-on-T Phenomenon
Report: Top: Rhythm of uncertain origin, 57 - 67/min Intraventricular conduction delay QRS 0.20â VEB, R-on-T phenomenon Ventricular fibrillation Middle : Ventricular fibrillation DCC and CPR artefact Bottom : Idioventricular or junctional rhy
Contrast-Induced Ventricular Fibrillation
Report: Sinus rhythm Sinus tachycardia VEBs Ventricular fibrillation Comment: It is surprising that this complication does not happen more often. The incidence was 0.75% in Gensiniâs large series125, but may be larger in less experienced hands. T
Idioventricular Rhythm in Advanced AV Block
Report: Sinus rhythm Advanced (high-grade) second degree AV block Left bundle branch block Idioventricular escape rhythm Right bundle branch block morphology Ventricular fusion beats Comment: The escape rhythm originates from the distal left bundle
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
