Alternating Ventricular Tachycardia
Report: Ventricular tachycardia 136/min Alternating QRS morphology throughout Comment: This is a good example of how alternating and bidirectional tachycardia are basically the same. This one would be called bidirectional if only the negative axis in
CPR Artefact
Report: Junctional bradycardia < 30/min CPR artefact 130/min Presumptive electro-mechanical dissociation (EMD) Comment:The patient had numerous episodes of true pulseless VT and VF. This strip was kept as a representative record. The confusing feature
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
VT: R in V1: Sharp Upstroke and Slurred Descent
Report:Ventricular tachycardia 186/min Comment:The qR in V1 (and V2) has a sharp ascent and slower descent, an equivalent of the rabbit-ear sign of VT112. In the frontal plane, the QRS axis is in no-manâs land at about +260o. There is little reason to
Thioridazine Overdose
Report:Junctional/sinus rhythm VEB, dimorphic couplet Non-sustained ventricular tachycardia (torsade de pointes) Comment:The torsades were very frequent, but the 12-lead ECG did not catch the best of them. Nevertheless, the one shown here is reasonably
Sotalol Sensitivity
Report:Atrial ?junctional bradycardia 42/min VEB Long QTc 0.54â Comment:The first beat is distorted by movement artefact: its repolarisation in L1 and L3 and preserved QRS shape in simultaneous L2 distinguish it from a VEB. The striking abnormality
Fascicular Ventricular Tachycardia
Report:Ventricular tachycardia 141/min Comment:The complexes are between 0.10 and 0.12â in duration (even narrower than in Case 11), with left axis deviation â40o. The morphology is that of incomplete LBBB except for the all-important lead V1, where
Fascicular VT with 1:1 Retrograde Conduction
Report:Ventricular tachycardia 106/min 1:1 retrograde conduction Comment:This is a very slow VT â well within what some authorities would call AIVR. It is fascicular, with the QRS complex only 0.12â long. Its morphology is that of basic RBBB/LAHB, o
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
Non-Sustained Right Ventricular Outflow Tract Tachycardia
Report:Sinus tachycardia 110/min Triplets of ventricular tachycardia 180/min Borderline right atrial abnormality (RAA) Comment:This patient was ventilated for unexplained respiratory failure, thought to be vasculitis masquerading as asthma. She had mod
