Dear Ivo van der Bilt
According this paper Naming of the waves in the ECG, with a brief account of their genesis, first use of PQRST was made by Einthoven for mathematically corrected curve of capillary electrometer. Can you kindly provide paper of Du Bois-Reymond?

Dear DS, These links will provide you with the paper of Du Bois - Raymond. I have had a quick look at the first link which is rather lengthy. But on page 183 at least the Q and S waves are mentioned. As frog legs probably do not show any P waves I doubt that these can be found in his paper.

Your image showing a heart with 300 trillion cardiomyocytes is incorrect and should be removed, there are not even that many cells in the entire human body.
