Bidirectional Ventricular Tachycardia
Report: Bidirectional ventricular tachycardia Probable digoxin toxicity Supraventricular rhythm of uncertain origin ? atrial fibrillation VEB Multiform ventricular tachycardia Comment: Despite the adverse prognosis and her age, she was discharged hom
Bigeminal Ventricular Tachycardia
Report: Monomorphic ventricular tachycardia 90 â 110/min Alternating cycle length, with bigeminy Retrograde conduction, 1:1 Probable old anterior infarction Comment: Most of the rate variation is in the long cycles. The basic mechanism is probably
R-on-T Ventricular Fibrillation
Report: Sinus tachycardia Second degree AV block VEBs Bigeminy R-on-T phenomenon Ventricular fibrillation ST segment elevation consistent with epicardial injury Comment: The VEB with the shortest coupling interval initiates VF. It comes right on to
Bigeminal Ménage à Trois
Report: Sinus tachycardia 105/min Intraventricular conduction delay QRS 0.12â VEBs, couplets Bigeminy Ventricular fusion beats Comment: The conducted sinus beats, with the VEBs, come in three varieties: âpureâ sinus or âpureâ ectopic bea
VEBs: (Con)fusion Bigeminy
Report: Sinus rhythm VEBs, late-diastolic, in bigeminy Ventricular fusion beats Comment: There are, depending on the VEBsâ timing, different degrees of fusion. Note how the sinus contribution is proportional to the PR interval of the fusion beat: t
Bizarre Trigeminy
Report:Atrial fibrillation Advanced or complete AV block Ventricular (first triplet) and junctional escape beats VEBs in couplets Trigeminy Small voltage, frontal leads Vertical heart position Possible old anteroseptal infarction Comment:There is
Parasystole[!xe "Parasystole" \t "See Ventricular parasystole"!]
Report: Sinus rhythm Ventricular parasystole 41 - 43/min Comment: The diagnostic feature, unrecognised by the xylocaine pushers, is the variable coupling interval and the fixed interectopic one. And the fusion beat. Parasystole is, generally, resistant
QRs VEBs in V1
Report: Sinus rhythm VEBs, late-diastolic, in bigeminy Comment: The VEBs have an Rs morphology; the Q wave is in fact a superimposed, dissociated sinus P wave. The dissociation is incomplete in the case of the 6th and the 10th complex, where âa tad of
Bigeminal Ventricular Tachycardia
Report:Ventricular tachycardia 173/min Alternating cycle length Comment:The patient had presyncopal paroxysms of VT, though to be SVT by many because of its relatively narrow QRS. They were even more convinced when, in Casualty, he reverted to sinus rhy
VEB couplets: Two for the Price of One
Report: Sinus rhythm 78/min VEBs, frequent, some in couplets (pairs) Poor R wave progression Nonspecific ST/T changes Comment: The VEBs have typical qRRâ morphology, with left rabbit ear taller than the right; the pauses are fully compensatory. The
