Alternating Retrograde Conduction in Accelerated Junctional Rhythm
Report:Accelerated junctional rhythm 92/min 2:1 retrograde block Right axis deviation Lateral infarction, acute or recent Borderline small voltage in frontal leads Electrical alternans V1 Comment:One would be tempted to say that this trace is an exa
Slow Ventricular Tachycardia
Report:Ventricular tachycardia 120/min Comment:The morphology in V1, with dominant left rabbit ear in a monophasic R complex, and of positive precordial concordance, is practically diagnostic of ventricular ectopic origin. This tracing is of interest be
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
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
Ventricular Tachycardia: Pre-Existent LBBB with Right Axis Deviation
Report: Ventricular tachycardia 167/min Comment: The diagnosis is based on RV1 morphology and the Northwest axis. In addition, the patient was known to have a pre-existing LBBB with RAD (a marker of congestive cardiomyopathy) shown below (Fig 89a). Lead
