Abstract
We describe a case of a 60 year-old man after inferior wall myocardial infarction with intermittent preexcitation syndrome.
In ECG, the pathologic Q waves in the inferior leads were masked by the intermittent preexcitation. In this patient, paroxysmal
asymptomatic second-degree atrioventicular block coexists with inconstant atrioventricular conduction maintained by
the accessory pathway, periodically 2:1.
