WebApr 25, 2024 · The unit of parameter B and C is ohm and mho, respectively. To find the value of T-parameters, we need to open and short circuit the receiving end. When the receiving end is open-circuited, receiving end current I R is zero. Put this value in the equations and we get the value of A and C parameters. From equation-1; From equation-2; 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.
