Electrocardiographic Changes in a Case of Left Ventricular and Septal Hypertrophy Resembling Anterior Myocardial Infarction
In certain instances of left ventricular hypertrophy, deep Q waves observed in the precordial electrocardiogram may resemble those of anterior myocardial infarction. Such a case is reported in a patient with syphilitic aortic insufficiency. Pathologic examination ruled out the diagnosis of infarction and revealed marked hypertrophy of left ventricular wall and the interventricular septum. The latter was of unusual degree and was probably responsible for the presence of large Q waves in precorldial leads representing, the normal activation of the upper part of the interventricular septum which in cases of septal hypertrophy presumably originates a vector of greater magnitude.
