This patient has atrial fibrillation with slow atrioventricular conduction. During an AF episode with preserved atrioventricular conduction, ventricular rhythm is generally irregular, rapid and greater than bpm, although remains much lower than that of the atria.
There is indeed a functional "block" at the junction due to the duration of the refractory period of the atrioventricular node. There are, however, certain peculiarities to be known. The ventricular rate can be very slow, as in this patient, with a rate of less than 40 bpm.
A regular ventricular bradycardia suggests the presence of a complete AV block with total interruption of conduction accompanied most Voir la suite de cet article sur Cursus ECG Exergue The diagnosis of atrial fibrillation should be focused on the evidencing of an irregular, disorganized and very rapid atrial activity.
The presence of a rapid and irregular ventricular rate is common but is not a prerequisite for diagnosis. Indeed, as in this patient, the ventricular rate may be slow and relatively regular in the presence of an atrioventricular conduction disorder. Aller au contenu principal. En savoir plus.
