Bigeminal Ventricular Tachycardia
Report: Monomorphic ventricular tachycardia 90 â 110/min Alternating cycle length, with bigeminy Retrograde conduction, 1:1 Probable old anterior infarction Comment: Most of the rate variation is in the long cycles. The basic mechanism is probably
Fascicular VT With Retrograde 2:1 Block
Report: Ventricular tachycardia 122/min Retrograde 2:1 V-A block “Retrograde 1o VA block (RP 0.24â)” Comment: The tachycardia originates in the posterior-inferior fascicle of the left bundle branch - it looks like atypical RBBB + LAHB. Despite the r
Reentry (Echo) Beats of Ventricular Origin
Report: Sinus rhythm VEBs Bigeminal Couplets & triplets Retrograde VA conduction First degree VA block Wenckebach conduction Reentry Post-ectopic sino-atrial depression Junctional escape beats Comment: There are two reentry beats: third last in
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
Slow Bidirectional Tachycardia
Report: Bidirectional tachycardia 104/min Retrograde VA conduction Junctional escape beats AV dissociation Sinus rhythm 95 â 98/min Overdrive (post-ectopic) SA suppression Comment: The rhythm is obviously bigeminal, with narrow rSRâ complexes
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
Retrograde Block in Ventricular Tachycardia
Report:Ventricular tachycardia 118/min 1:1 retrograde conduction (top) Ventricular tachycardia 180/min 2:1 retrograde block (middle) Comment: The retrograde atrial waves are seen as typical sharp upright deflections in MCL1 or V1 (Marriott lead). T
Complex Complex of Complex Complexes
Report: Ventricular (fascicular) tachycardia 139/min Retrograde VA block , Möbitz 1 Incomplete Wenckebach sequences Reentry (echo) beats of ventricular origin Comment: As shown on the laddergram below, the longest retrograde RP interval in each tripl
