[Focal junctional tachycardia in adults. Anatomo-electrophysiological aspects apropos of a case].
The authors report the case of a 65 year old patient with focal junctional tachycardia complicating infectious myocarditis which had a fatal outcome. The ECG recordings showed episodes of tachycardia alternating with junctional rhythm at 90/min. There were signs of retrograde conduction. The anatomopathological findings were typical of acquired myocarditic lesions in the lower part of the atrioventricular node with congenital abnormalities, in particular a bifid node and His bundle with an accessory paraseptal atrioventricular bundle. This is the first description, to the best of the authors's knowledge, of junctional tachycardia associated with a latent pre-excitation.
