Alternate Cycle Antecedent P Waves
Report:Ventricular tachycardia 125/min Probable 2:1 retrograde conduction Comment:The diagnosis of VT is supported by the QRS duration of 0.18â, the indeterminate abnormal axis and the left rabbit ear in V1 being taller than the right. The relativel
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
Double Defibrillation
Report:Atrial fibrillation. VEBs Multiform ventricular tachycardia Spontaneous termination (top) Transition to ventricular fibrillation (middle) Accelerated idioventricular rhythm (bottom) 70 - 76/min Retrograde conduction (first four and last two b
Escape-Capture Quadrigeminy
Report: Sinus rhythm First degree AV block (PR 0.28â) Incomplete right bundle branch block (Slightly) accelerated ventricular (fascicular) rhythm 69 - 72/min Sinus capture beats Comment: The PR interval would probably be shorter without the inter
Parasystole
Report: Sinus rhythm Ventricular parasystole Comment: The parasystole behaves like a fixed-rate pacemaker, except there are no spike artefacts to mark its beats between ventricular captures. Fusion beats are common in parasystole, but the essential aspe
Monomorphic Ventricular Tachycardia: RV1 & QSV4-6
Report: Ventricular tachycardia 214/min Comment: The monophasic R in V1 and QS in the left ventricular leads is practically diagnostic of VT. Absence of R waves in V4-6 also precludes an antidromic pre-excited tachycardia99. The patient ascribed the ar
Fast Ventricular Tachycardia with Visible AV Dissociation
Report: Ventricular tachycardia 214/min AV dissociation Comment: The morphology is somewhat equivocal, V1 showing RRâ complexes with right rabbit ear taller than the left; nevertheless, they are essentially monophasic and over 0.14â, favouring ectop
Accelerated Idioventricular Rhythm in Complete AV Block
Report: Sinus tachycardia 120/min Accelerated idioventricular rhythm 65/min Third degree AV block Comment: One can confidently diagnose complete AV block when the atrial rate is so much faster than the ventricular, without any captures, the ventricular
Parasystole
Report: Sinus rhythm Ventricular parasystole Ventricular fusion beats Comment: Identical VEBs with different coupling intervals but a constant interectopic interval (or an exact multiple thereof) constitute parasystole. The protected ventricular focus
Repetitive Multiform Ventricular Tachycardia
Report: Sinus tachycardia 108/min Repetitive multiform ventricular tachycardia 118-280/min Comment: There is no mistaking the bursts of VT for aberrancy. It may well be a ventricular form of the Parkinson-Papp syndrome â runs of tachycardia separated
