Abstract
The clinical everyday management of blood pressure (BP) and heart rate (HR) can be greatly improved by the mapping of time structures in home ambulatory BP and HR assessment. Thereby, we change focus from the BP and the HR to the dynamics of these variables. This change is achieved by computer-implemented chronomics, the mapping of chronomes, consisting of cyclicities (our concern herein) along with chaos and trends, in the service of cardiologists, general health care providers, the educated public, and transdisciplinary science. We here further illustrate the yield of chronomics in research on long BP and HR series covering years, some several decades long, and on archives of human sudden cardiac death revealing magnetoperiodisms, e.g., "years" longer than a calendar year, i.e., transyears. In this case of cardiac arrest, what we do not see, the 16- to 20-month transyear is prominent, in the absence of any signature of the calendar year, and so can be a cis-half-year of about 5 months.
