VT or SVT in a Patient with Known LBBB?
Report:Ventricular tachycardia 174/min. Comment:The QR morphology in lead V1, however, is that of VT, unless there was a previous anteroseptal infarction. The marked LAD -90o is neither here or there, diagnostically. Interestingly, a recent study using t
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
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
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
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
LBBB-like Ventricular Tachycardia
Report: Ventricular tachycardia 168/min Comment: Some would say that the precordial pattern is that of negative concordance. A purist would point out that there are small R waves in V2 or V6; the complexes are not all completely negative. This fortunatel
No Response to DC Cardioversion
Report: Probable atrial flutter or fibrillation Non-sustained monomorphic ventricular tachycardia 160/min Inferior infarction ?age Comment: The patient was one of those surgical disasters that attract multiple medical consultations in the hope of expla
Multiform Ventricular Tachycardia
Report: Atrial fibrillation Runs of multiform ventricular tachycardia 150 â 180/min Right axis deviation +165o Probable right bundle branch block Acute inferior infarction Comment: There are only four pure supraventricular beats to be seen â two
LBBB-Like VT in Patient with RBBB
Report:Ventricular tachycardia 178/min LBBB morphology with right axis deviation Comment:This is, morphologically, right ventricular outflow tract (RVOT) tachycardia, with LBBB and marked right axis deviation (not seen in aberrant conduction8). The morp
