Par ailleurs, une lecture attentive de ce trac\u00e9 montre que la dur\u00e9e des intervalles PR , s’accroit progressivement jusqu’\u00e0 ce qu’une onde P (et une seule) soit bloqu\u00e9e.<\/p>\n\n\n\n

L’ allongement progressif de l’intervalle PR avant le blocage de l’onde P est caract\u00e9ristique des BAV2 de type M\u00f6bitz-1.<\/p>\n\n\n\n

Ce type de bloc atrio-ventriculaire du 2e degr\u00e9 est peu fr\u00e9quent.<\/p>\n\n\n\n

Ce rythme est aussi appel\u00e9: P\u00e9riodes de Luciani-Wenckebach. Ces p\u00e9riodes correspondent au nombre d’ondes P conduites compar\u00e9 au nombre de QRS.<\/p>\n\n\n\n

Ici, on est en pr\u00e9sence de p\u00e9riodes de type: 4:3 (4 ondes P pour 3 QRS) .<\/p>\n\n\n\n

On rencontre parfois des p\u00e9riodes variables sur un m\u00eame trac\u00e9.<\/p>\n\n\n\n
