| Popis: | 1. 1. Five cases with giant negative T waves have been presented. These, as the ones previously reported, demonstrate its reversibility, low mortality, and no serious impairment of function upon recovery. 2. 2. There was definite improvement in the T-wave pattern after the administration of oxygen, nitroglycerine, aminophylline, and papaverine. 3. 3. The experimental work and clinical course of myocardial infarction suspects point to the fact that these changes represent, most likely, subepicardial ischemia and that the prognosis is chiefly determined by the coexistence of complicating factors and the severity of the underlying disease. 4. 4. In patients with coronary artery disease giant negative T waves may represent a subepicardial ischemic area superficial to a subendocardial necrotic zone, but the mechanism responsible for this pattern in other conditions is not known. |
