[Transient left posterior hemiblock in acute ischemic cardiopathy].

Report of seven cases of intermittent left posterior hemiblock in subjects with acute ischaemic heart disease. The electrocardiograms of all the patients (together with the coronary arteriography in three cases) have shown the presence of two different areas of ischaemia: the anterior wall and the diaphragmatic wall of the left ventricle. In three patients acute coronary ischaemia was present in both areas; in the other cases one myocardial wall only was involved.
