Web3 de abr. de 2024 · If the “U” wave in hypokalemia is excluded, there are no identified clinical consequences to the presence of a U wave on the ECG. It is remarkable that since its identification 100 years ago, the mechanism of the U wave is just now being elucidated. Jennifer has the long QT syndrome. It will be important for her to avoid certain medications. According to V. Gorshkov-Cantacuzene: "The U wave is the momentum carried by the blood in the coronary arteries and blood vessels". The resistivity of stationary blood is expressed as , where is a coefficient, and is the hematocrit; at that time, as during acceleration of the blood flow occurs a sharp decrease in the longitudinal resistance with small relaxation times.
