A cycle with an about (~) 7-day (circaseptan) period, τ, in the heart rate (HR) of 5 humans resonates with solar activity; it is a coperiodism insofar as the HR's amplitude, A, at the ~7-day τ is amplified in the presence of corresponding ts in rate of change of sunspot area and damped in the latter's absence. The τ is not lost in HR, likely built into living matter by evolution. How this and other coperiodisms with a τ longer than 28 hours, infradians, come about along the scale of fast ultradian cycles is considered herein, up to circaseptans and their harmonics and subharmonics. From a physical viewpoint, several kinds of molecular processes could be involved: 1. Diffusion of charged molecules in magnetic fields with the oscillating x for Ca2+ and K+ being of ~1 week; and 2. quantum mechanical perturbation and its resonance dominators, characterizing specific interactions among constituents, that permit the treatment of molecular processes by circuits with characteristic resonances and beat-frequencies, which result from the primarily fast physical processes. As examples the tunneling processes between DNA base pairs (H bonds) and the decomposition of ATP are considered. While we had earlier considered mechanisms of circaseptans by diffusion at the atomic level, we now turn to quantum mechanical resonances with the goal to describe the influence of the electromagnetic field by a fundamental principle.
