0 relating to the connection between the atrium (= upper space) and ventricle (= lower space) of the heart --

He had electrocardiographic evidence of intact atrioventricular nodal conduction through 9 years, and was troubled by recurrent supraventricular tachycardia throughout this period of time.
Atrioventricular nodal block, therefore, should preclude the development of this common type of tachyarrhythmia.
Intracardiac inspection through a right atriotomy confirmed the discordant atrioventricular connections.
An electrocardiogram showed sinus rhythm with first degree atrioventricular block that advanced intermittently to second degree atrioventricular block.
His atrioventricular conduction was intact until 9 years of age, after which time he developed progressive atrioventricular block.
Strong consideration should be given for permanent pacing in patients whose only source of atrioventricular conduction is via a bypass tract.
Small vegetations were observed on both the atrioventricular and arterial valves.
In both there was usual atrial arrangement with concordant atrioventricular and ventriculoarterial connections.
