Right Ventricular Outflow Tract Tachycardia
Report:Ventricular tachycardia 155/min Possible A-V dissociation Comment:The tachycardia complexes are just under 0.12â in duration and have, in a way, left bundle branch block morphology with marked (+100o) right axis deviation. There appear to be di
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
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
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
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
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
Complex Trigeminy: Quadrigeminy in Disguise
Report: Sinus rhythm 73/min VEB couplets in trigeminy Ventricular fusion beats (second in each couplet) Concealed retrograde conduction Comment: The first VEB is interpolated between the preceding sinus beat and a fusion beat; hence the fusion beats h
VEBs: Retrograde Conduction
Report: Sinus rhythm VEBs, trigeminal, uniform Retrograde VA conduction Left atrial abnormality (LAA) Borderline right atrial abnormality (RAA) Probable old posterior infarction Nonspecific ST/T changes Comment: The compensatory pauses are longer t
Ventricular Flutter
Report: Top: Ventricular flutter 300/min Middle: Accelerated idioventricular (?junctional) rhythm 78/min Sinus capture beats Probable AV dissociation Bottom: Atrial tachycardia 113/min Comment: In ventricular flutter, the distinction between QRS,
