Ventricular Tachycardia in a Patient with Permanent Pacemaker
Report: Ventricular tachycardia 154/min ?Retrograde VA conduction Comment: The QRS is a monophasic R wave in V1, just over 0.16â long: both the morphology and the QRS duration support the diagnosis of VT. The duration criterion is > 0.14â for V1 pos
A Unique LBBB Aberrancy
Report: Probable supraventricular tachycardia 182/min Right axis deviation +110o LBBB Comment: The QRS complexes in V1-2 take almost 0.08â to reach the nadir of their S waves, but this is not immediately obvious on inspection. The initial QRS in V1 i
Shifting Rabbit Ears in VT
Report: Ventricular tachycardia 152/min Possible old anterior infarction Comment: There is a monophasic R, possibly a qR, in V1, with northwest axis in the standard leads and QSs in V5-6. The patient in fact had an old anterior MI (Fig 106a below, in AF
Milrinone-Induced Bidirectional Ventricular Tachycardia
Report: Atrial fibrillation with rapid response VEBs, some in dimorphic couplets Four-beat run of bidirectional ventricular tachycardia 126/min Comment: The VT obviously consists of two dimorphic couplets in a row; its significance in the absence of di
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
Fascicular Ventricular Tachycardia & Positive Concordant Precordial Pattern
Report:Ventricular tachycardia 198/min Comment:Fascicular ventricular tachycardia12,13 is distinguished by the relatively narrow QRS width and marked axis deviation in the frontal plane; in this case the QRS lasts just under 0.12â, less than in sinus r
Ventricular Tachycardia : Narrower QRS in VT
Report: Top: Sinus arrhythmia Borderline first degree AV block VEBs Rate-dependent right bundle branch block Bottom: Sinus rhythm Right bundle branch block Ventricular tachycardia 148/min AV dissociation Comment: The tachycardia in the bottom st
Precordial Masquerading Bundle Branch Block
Report :Atrial fibrillation with rapid ventricular response 138/min Northwest axis +260o Right bundle branch block (Probable) left anterior hemiblock Possible old anterior myocardial infarction Nonspecific ST/T changes Positive concordant precordia
Killip-Gault Rule and Exception
Report: Sinus rhythm and arrhythmia SVEBs 9 beat run of (probable) atrial fibrillation Rate-dependent bundle branch block, probably LBBB Comment: This is Lead 2 and one cannot tell with certainty that the IVCD is, specifically, LBBB. It looks like it,
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
