Discussion:
Germaine: Blood pressure is typically lower at night, higher during day. Alteration in circadian rhythms can be indicative of disease. Better than mean, smaller errors, & reduce other abnormalities. Eg. Large amplitude. Treatments include relaxation, medication that reduces amplitude and mean value. Time on treatment can affect amount required, side effects, impact on circadian rhythm. Two day span measurements may differ. Mesor-hypertension & CHAT. Seven day profiles are predictive of representative of behavior that occurs over 50 percent of the time. It is of interest to identify trends - e.g. Worsening diseases. Leads to treatments that can depend on symptoms. Eg. Fast acting drug vs. slow acting drug.
Indirect measurements require time & direct measurements are instantaneous. 4/dy is minimal, 24/dy is adequate, 48/dy is better.
In future include: Jim Holte, Earl Bakken, Brian Brockway.
Chris: There are implantable devices. How expensive?
Franz: Like a pen, would be good. Current devices are way too expensive. And as easy to use as current.
