Auricular infarction

Abstract

Three cases of distinct auricular infarction, without ventricular involvement, are presented. A fourth case in which the electrocardiograms showed changes apparently typical of auricular damage proved to be one of ruptured, false aneurysm, with hemorrhagic infiltration of the auricles. The first case was interesting because of the unfortunate location of the small infarct; it might have been less serious if it had been located in the ventricle. In three of the four cases there were deviations of the P-Ta segments conforming to that described as typical of auricular damage. In one there was also an apparent disturbance of the A-V conduction pathway; this was most likely due to the ulceration through the interventricular wall. All of the infarcts were located in the right auricle.
