Isolated U wave negativity.
Inversion of U as the only abnormal electrocardiographic finding is here shown to be the first change to occur in certain cases of hypertension, coronary artery sclerosis, and other organic heart disease. It is also found in association with certain metabolic and electrolyte changes. Its recognition will enhance the value of the electrocardiogram in clinical diagnosis. T HE CLINICAL significanc...
متن کاملMorphologic aspects of the negativity of the U wave and their corresponding electrocardiographic and clinical data.
The negative U wave has been studied in 200 electrocardiograms. Six different types of negativity of the U wave are recognized; a seventh type includes the alterations of the T-U segment. Electro-cardiographic and clinical data are correlated with these changes. Two hypotheses to explain the vairing morphology of the negative U wave are discussed. U NTIL quite recently neither the genesis of th...
متن کامل" Isolated T - Wave Negativity in the " Isehemic Phase " of Myocardial Infarction in Man
INVERSION of the T wave has been described as the immediate consequence of experimental ligation of the descending branch of the left coronary artery.1-3 It is only on more prolonged occlusion that changes develop in the RS-T segment or in the QRS complex. In acute coronary thrombosis in man, by contrast, an elevation of the RS-T segment is generally the earliest change recorded. This may be as...

متن کاملU wave inversion.
The U wave, when first recognized by Einthoven (1906) in the earliest days of electrocardiography, was considered by him to be pathological. Since then the normality of upright U waves, except perhaps in cases where they are unusually high (Katz, 1946), has been generally conceded. Various hypotheses have been advanced to explain the U wave, of which the most satisfactory is that of Hoff and Na...
