Electrocardiogram and Vectorcardiogram
نویسنده
چکیده
Y THE TIME the patient with acute myocardial infarction is first examined, his electrocardiogram may already show changes in the RS-T segment alone, in the T wave alone, in the QRS complex alone, or in any combination of the three. Changes in any of these portions of the ventricular complex and particularly in the QRS may not appear for hours or days. Some never show distinctive electrocardiographic changes; in these the diagnosis must rest upon other than electrocardiographic evidence. The changes in the QRS complex generally long outlast the changes in RS-T and T and ordinarily constitute the telltale evidence of previous infaretion for the remainder of the patient's life.

The vectorcardiogram in mitral valve disease.
The Frank system vectorcardiogram has been studied in 61 patients with severe mitral valve disease to determine the value of the vectorcardiogram in the recognition of the relative degree of left and right ventricular hypertrophy in this situation. The appearance of the usual evidence of right ventricular hypertrophy is delayed in mitral valve disease by the vertical electrical position of the ...
متن کاملComparison of scalar and vector electrocardiographic diagnosis and localization of myocardial infarction.
A prospective study was made of 80 patients during typical clinical episodes of acute myocardial infarction with biochemical and scalar electrocardiographic confirmation. Nine patients had bundle-branch block and 12 had had previous episodes of myocardial infarction. Serial electrocardiograms and vectorcardiograms were recorded during the first week in hospital. The most striking finding was th...

IT HAS BEEN ARGUED that the vectorcardiogram should yield no more information than a standard 12-lead electrocardiogram. Yet many authors, including Wolff," 2 Burch,3-5 Scherlis and Grishman6 and Milnor,7 employing different lead systems, have published data indicating that the vectorcardiogram may demonstrate abnormalities not apparent in the electrocardiogram. Of a total of 2,545 vectorcardio...
