Spectrograms recognize multiple circadian periods by blood pressure and heart rate tensiometry

We focus here on spectrograms that could be integrated with sphygmochrons into an affordable tool for a Chronobiologically-interpreted record from Ambulatory Blood Pressure (BP) and heart rate (HR) Monitoring, C-ABPM (obtainable, e.g., via a website from any continuously monitoring home, school, hospital or other institution). This tensiometry serves to know what we dislike to the point of chronobiologically-assessed strain, impeding optimal performance, detected as Vascular Variability Anomalies (VVAs) in weekly summaries. C-ABPM also serves for the detection of Vascular Variability Disorders (VVDs) for disease risk detection in long-term C-ABPM, to check on the presence, intermittently or continuously, of multiple circadian periods, τs, here described in a 62-year-old woman's (JF) blood circulation. JF has a history of 20 years of twice-yearly adynamic depression. The goals here noted have been discussed and documented at several consensus meetings and workshops.
