Enhanced circasemiseptan (about 3.5-day) variation in the heart rate of cancer patients?
In addition to prominent circadian and circannual components, an about half-weekly (circasemiseptan) pattern was shown earlier to characterize mitotic activity in cancer patients. A circasemiseptan variation in heart rate and circadian rhythms in heart rate and axillary temperature of cancer patients are assessed herein. These variables could be tested as putative marker rhythms for the optimization of radio- and/or chemotherapy by timing which, from a practical viewpoint, may be easier to implement along the scale of the week than that of the day.
