I have a univentricular setup. My artrial blood is pumped out into the body by my left ventricle, but where it would normally be driven back by a propulsive thrust from the right heart, there's only passive drainage against gravity...

The pressure gradient in my pulmonary artery and my skeletal muscle pump - i.e. my legs - is all I got to drive venous return. Blood pools south of the heart.

I desaturate extensively under load which causes a more rapid switch from Type I to to Type IIb fibres. Can't figure out if compression socks are good or bad during training. They help venous return but could reduce local tissue oxygenation and nuke my gains.
