WebT Wave. The T wave corresponds to phase 3 repolarization of ventricular myocytes. The normal T-wave amplitude is variable and is not routinely quantitated. On the other hand, the direction of the T wave deserves careful attention. As mentioned, the T-wave axis should follow the same net direction as the QRS in the frontal plane within about 60 ...

WebU wave amplitude is usually < 1/3 T wave amplitude in same lead. U wave direction is the same as T wave direction in that lead. U waves are more prominent at slow heart rates and usually best seen in the right precordial leads. Origin of the U wave is thought to be related to after depolarizations which interrupt or follow repolarization. WebMeasurement of T up can be difficult, especially in positive T waves. These difficulties have led some researchers to propose the instant of maximum downslope ( Tdown) as a marker of T R when the T wave is positive. To improve understanding of T-wave parameters, we simulated electrograms with a bidomain model of the human heart. tarkasian
