title: [Inter- and intra-atrial blocks].
abstract: Inter and intra atrial-blocks are secondary to disorders in the conduction through the auricles of the sinusal impulse. These blocks are a consequence of important relays in the stimulation of the left auricle in respect to the right one. In these intra-atrial blocks there are two areas to auricular level, responding to different rhythms, because they are separated by a bi-directional block. In this paper we present three patients with various diseases; the first showed a persistent inter-atrial block, and the other two tanscient, intra-atrial blocks which persist through the whole acute process causing the interment of the patient in our Hospital.
