Why the study?
Does the recognition of isolated U wave inversion on electrocardiogram improve clinical diagnosis of early heart disease or metabolic/electrolyte changes?
Does the recognition of isolated U wave inversion on electrocardiogram improve clinical diagnosis of early heart disease or metabolic/electrolyte changes?
Isolated U wave inversion on an ECG can serve as an early diagnostic marker for organic heart disease and metabolic or electrolyte disturbances.
Isolated U inversion may flag early organic disease; leaves open its added diagnostic value in contemporary ECG interpretation.
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.
