VEBs: Couplets & Concealed Retrograde Conduction
Report: Sinus rhythm Left atrial abnormality (LAA) PR interval 0.20â Intraventricular conduction delay (QRS 0.12â) VEBs in couplets Triplet (or more, end of bottom strip) of ventricular tachycardia 102/min Concealed retrograde conduction Comm
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
R-on-P Phenomena
Report:Sinus rhythm Runs of ventricular tachycardia R-on-P âphenomenonâ Concealed retrograde conduction (top strip, end of VT) Possible ventricular fusion beat (onset of VT in bottom strip) Comment:This patient did well following intubation; no s
Fusion Beats Starting Runs of VT
Report:Sinus arrhythmia Ventricular tachycardia 132-185/min, non-sustained25 1:1 retrograde conduction Fusion beat Comment: The fusion beat starting the paroxysm of VT is diagnostic of the ventricular origin of the latter. Dressler beats are fusion
