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
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
Fascicular Ventricular Tachycardia
Report:Ventricular tachycardia 141/min Comment:The complexes are between 0.10 and 0.12â in duration (even narrower than in Case 11), with left axis deviation â40o. The morphology is that of incomplete LBBB except for the all-important lead V1, where
LBBB-Like VT in Patient with LBBB
Report:Ventricular tachycardia 125/min 1:1 retrograde conduction Spontaneous termination Sinus rhythm VEBs, one couplet Comment:The QS complexes in V1 take a very long time to reach the S wave nadir; the upstroke is quite sharp. This is the only reli
Runs of Ventricular Tachycardia
Report:Sinus rhythm 85/min VEBs, couplets Runs of ventricular tachycardia 164/min Left atrial abnormality (LAA) Left bundle branch block V2-V3 lead reversal Comment:The patient had many brief runs of VT, always introduced by the qR VEB couplets. The
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
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
Left Bundle Branch Block-Like Ventricular Tachycardia
Report:Ventricular tachycardia 196/min[! XE !] Comment:This is a rapid VT with morphology quite similar to LBBB. The QRS duration is about 0.16â, best measured in the inferior leads. However, in V1, normally the most important diagnostic lead, it looks
Another Variant Form of Bidirectional Ventricular Tachycardia
Report: Bidirectional ventricular tachycardia 184/min Comment: Like in the preceding case, lead V1 has basic LBBB morphology. This patient, with known pre-existing LBBB, received adenosine for presumptive SVT, without effect. Sotalol, 80 mg IV, abolished
Positive Concordant Precordial Pattern in VT
Report: Ventricular tachycardia 175/min Comment: The diagnosis depends on: - concordant (positive) precordial pattern - monophasic R wave in V1 - AV dissociation - known pre-existing LBBB62 Below (Fig 67a) is his 12-lead ECG 3 hours earlier, in mult
