Journal of Clinical Investigation published in 1940 that perfusing a dead heart with 400 mm hg generates current from endocardium to epicardium of one half millivolt. https://www.jci.org/articles/view/101181/pdf
>_"With a pressure of 40 cm. of mercury an amount of current in excess of one half millivolt was produced. "_
>_"These facts are significant in that they indicate that the T-wave is a product of cardiac contraction and contradict the current explanation based on the theory of repolarization. "_
This supports that the heart is an electrical generator that relies on pressure to generate osmotic electrical currents.
I have proven similar things in other physiological systems, most importantly the loop of Henle.
