VT or VF?
Report: Supraventricular rhythm, probably sinus with SVEBs R-on-T VEBs Ventricular fibrillation Comment: It is sometimes quite difficult to determine if a very fast ventricular rhythm is multiform VT, perhaps torsades de pointes, of VF. This trace was
Runs of Anomalous Conduction
Report :WPW syndrome Atrial fibrillation Runs of anomalous conduction (Wolff-Parkinson-White type âAâ) Borderline small voltage and T wave changes in frontal leads Comment :Syndrome, rather than mere conduction, because of the arrhythmia. The p
Broad QS Morphology in Standard and Left Precordial Leads
Report :Sinus rhythm VEB, possibly fusion beat Runs of ventricular tachycardia 210 â 150/min Non-specific ST/T changes Probable old anterolateral infarction Comment :All the VT complexes have QS morphology. In the left precordial leads, this abse
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
Non-Sustained Ventricular Tachycardia: Fusion and Narrow Capture Beats
Report:Sinus tachycardia 108/min Runs of ventricular tachycardia 134/min Fusion beats Possible old inferior infarction Nonspecific ST/T changes Comment:The diagnosis of ventricular tachycardia is based on (i) R or qR complexes in V1; (ii) A-V dissoci
Slurred R Ascent in V1: Exception to the Rule
Report:Ventricular tachycardia 168/min Comment:The contour of V1 suggests a rabbit in profile, with overlapping ears â not very helpful. If one, more properly, imagines looking at the rabbit from behind, there is a suggestion of larger right ear â no
Accelerated Idioventricular Rhythm
Report:Accelerated idioventricular rhythm 96/min AV dissociation Fusion beat Sinus rhythm 98/min Anterior infarction ?age Comment:This has, at times, been called slow VT. There is no such thing: the term is a contradictio in adjecto. There can be no
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
