Pseudoventricular Tachycardia
Report:Atrial tachycardia 145/min Left bundle branch block Primary ST/T changes consistent with ischæmia Comment:The sole evidence for the ectopic ventricular provenance of the tachycardia resides in the broad R wave in lead V1 (Rosenbaumâs ânorma
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
Small Ectopics
Report:Sinus rhythm. VEBs. Junctional escape beats. AV dissociation. Retrograde conduction (of VEBs). Comment:The small complexes are probably VEBs, although aberrant junctional beats cannot be excluded. A 12-lead ECG would help. Note the mirror-imag
Acute Infarct Pattern in Ventricular Tachycardia
Report: Ventricular tachycardia 120/min Spontaneous termination & onset in the (subsequent) rhythm strip Sinus escape beat Probable anterior infarction Comment: There is little doubt about the acute anterior infarction, despite the bizarre 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
Upright Retrograde P Waves
Report: Ventricular tachycardia 154 - 142/min Retrograde 1:1 conduction Upright retrograde P waves? Spontaneous termination after slowing to 142/min Junctional escape complex Non-specific ST/T changes VEB Comment: The tachycardia resembles, superfi
Pseudo P Waves
Report:Ventricular tachycardia 102/min Sinus rhythm 70/min Sinus capture (fusion) beats with first degree AV block Comment:The initial QRS forces mimic a P wave70 and would be difficult to differentiate from it were it not for the presence of large, bi
Ventricular Tachycardia: Pseudo P Waves at Either Complex End
Report:Sinus rhythm 84/min. Ventricular tachycardia 132/min. Complete AV dissociation. Comment:The broad-complex tachycardia has QRS duration 0.20", extreme "Northwest" axis and, best of all, taller left rabbit ear in V1 to declare its ventricular orig
SVT with LBBB
Report: Supraventricular tachycardia 152/min Left bundle branch block Comment: The rS complexes in lead V1 are perfectly ânormalâ LBBB complexes in that the initial R wave is narrow, the S downstroke is sharp and the upstroke slurred. The frontal pl
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
