Fascicular VT with 1:1 Retrograde Conduction
Report:Ventricular tachycardia 106/min 1:1 retrograde conduction Comment:This is a very slow VT â well within what some authorities would call AIVR. It is fascicular, with the QRS complex only 0.12â long. Its morphology is that of basic RBBB/LAHB, o
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
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
Retrograde Conduction of AIVR: From the Second Beat Onward
Report: Sinus rhythm 75/min PR interval 0.20â Intraventricular conduction delay, probably LBBB QRS 0.12â Accelerated idioventricular rhythm (AIVR) 96/min Retrograde VA conduction RP interval 0.20â Comment: The retrograde and antegrade conduct
VEBs: Retrograde Conduction
Report: Sinus rhythm VEBs, trigeminal, uniform Retrograde VA conduction Left atrial abnormality (LAA) Borderline right atrial abnormality (RAA) Probable old posterior infarction Nonspecific ST/T changes Comment: The compensatory pauses are longer t
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
Small Ectopics
Report:Sinus rhythm. VEBs. Junctional escape beats. AV dissociation. Retrograde conduction (of VEBs). Comment:The small complexes are probably VEBs, although aberrant junctional beats cannot be excluded. A 12-lead ECG would help. Note the mirror-imag
Fusion Terminating AIVR
Report: Sinus rhythm 74 â 80/min Accelerated idioventricular rhythm 69 â 74/min Ventricular fusion beat Comment: The AIVR accelerates, but to no avail: the faster sinus rhythm takes over by the middle of the recording. Between the two is a typical
Onset of Retrograde Conduction
Report:Top: Sinus tachycardia 104/min VEB Monomorphic ventricular tachycardia 152/min Retrograde conduction Bottom: Sinus tachycardia 110/min Fusion VEBs in bigeminy Monomorphic ventricular tachycardia 150/min Retrograde conduction Comment:In bo
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.
