Right Ventricular Outflow Tract Tachycardia
Report:Ventricular tachycardia 155/min Possible A-V dissociation Comment:The tachycardia complexes are just under 0.12â in duration and have, in a way, left bundle branch block morphology with marked (+100o) right axis deviation. There appear to be di
Another RVOT VT: Retrograde 1:1 Conduction
Report:Ventricular tachycardia 168/min Comment:This is a good example where conduction sequences and QRS morphology do not help in making the diagnosis. Each QRS is followed after 0.18â by a sharp upright P wave in V1 consistent with a retrograde P wav
VT Triplet in AF with Rapid Ventricular Response
Report:Atrial fibrillation with rapid ventricular response 147/min Triplet of ventricular tachycardia Right axis deviation +120o Possible old anteroseptal infarct Possible LVH with ST/T changes (RV6 > RV5) Comment:The three RRâ complexes are too la
Slow Ventricular Tachycardia
Report: Ventricular tachycardia 116/min Retrograde conduction Probable acute anterior infarction Comment: The basic LBBB-like morphology with RAD alone designates the tachycardia as ectopic ventricular27; its slurred S downslope in V1-2 is also diagnos
Run of Ventricular Tachycardia
Report: Sinus rhythm 97/min VEBs Ventricular tachycardia 160/min AV dissociation Left atrial abnormality (LAA) First degree AV block PR 0.32â Left bundle branch block Comment: The last cycle of the VT is shorter than others, indicating an exit b
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
March of Rosenbaumâs Extrasystoles
Report:Sinus rhythm VEBs Runs of non-sustained monomorphic ventricular tachycardia 138/min Borderline left atrial abnormality Nonspecific ST/T changes Comment:By definition, non-sustained VT lasts less than ½ minute. It is a different species from s
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
Acute Infarct Pattern in Ventricular Tachycardia
Report: Ventricular tachycardia 120/min Spontaneous termination & onset in the (subsequent) rhythm strip Sinus escape beat Probable anterior infarction Comment: There is little doubt about the acute anterior infarction, despite the bizarre complexes.
Arrhythmogenic Right Ventricular Dysplasia
Report: Ventricular tachycardia 162/min Comment: The patient had dilated right atrium and ventricle, with normal, mildly hypertrophied left ventricle. The coronary arteries were also normal. In Casualty, adenosine 6 + 12 mg, verapamil 2.5 mg, then sotalo
