The corresponding intervals t correlate with the rates f by the formula t = 60.000
/ f (t in ms, f in ppm).

Rate Limitation changes as the Pacemaker approaches End of Service. The
Rate Limitation is nominally 190 ppm at Beginning of Service (BOS) and can
reach 220 ppm at End of Service (EOS) due to battery depletion.
