Abstract
We present new-onset sustained monomorphic ventricular tachycardia with relatively narrow QRS (width of QRS ª 120 ms)
in the recovery period after aortic valve replacement and surgical revascularisation in a patient with a prior inferior wall
myocardial infarction. Ventricular tachycardia probably originating from the left-side His-Purkinje system and mimicking
idiopathic posterior fascicular tachycardia was diagnosed. Placement of a bypass graft across occluded artery supplying an
infarct zone was a potential trigger of this arrhythmia.
