Because the direction of repolarization is exactly opposite, it is from the outside, that is why T wave appears positive.
But why repolarization happens from outside to inside?
As we know within the plateau we have the contraction, and the repolarization happens after the plateau, and during part of the repolarization we have some contraction.
The blood vessels are constricted so there will be enough wash out of the ions to go back to the normal, that is why the outside ( epicardium ) doesn't have as more contraction as the inside, the wash out easy in the outside but not in the inside so the repolarization starts from the outside and the T wave will appear positive.
Tampak di luar orang mungkin pantas melupakan, tapi di dalam bukan semudah itu.
memaafkan dan melupakan.
meninggalkan dan melupakan.
melupakan dan melupakan.
but on certain things, we definitely should start somewhere. somehow.
