Alterations Crises
of the S-T Segment and of Paroxysmal Tachycardia.
In four relatively young patients during or after prolonged and repeated crises of paroxysmal tachyeardia of supraventricuIar or ventricular origin, an opponent depression of the S-T segment and a negative T wave in Leads II and III (three cases) or in Leads I and II (one case) were observed. Autopsy of one case showed cardiac dilatation, integrity of the coronary vascular system, and absence of focal necrobiosis. The electrocardiographic alterations described are thought to be due to the enlargement of the heart or to right ventricular strain. But whatever their cause it is a fact that they cannot always be imputed to a real coronary insufficiency. Five other observations have been found in the literature, one of them with necropsy, confirming this conclusion.

An analysis was made of the electrocardiograms of 176 persons with intraventricular block. They were classified according to the differences in pattern found in the limb and chest leads. The types were related to the probable delay in stimulation of the right and left ventricles, as suggested by the averages of the Q-E intervals (the time from the onset of QRS to the rise of the subclavian arterial pulse) in each Further, an analysis of some detail was made of the findings in twenty-five group. autopsied cases.

Seven patients with severe heart disease appeared to have unfavorable prognoses at the onset of their illness but through natural recovery or sensible living were able to lead long and useful lives. This emphasizes the statement that in acute heart disease LLfunctional recovery may be so complete that the ultimate prognosis is good for many years after.” It is not to be inferred, however, that one may dispense with medical attention.
