Definitions of hypertension
Elevated arterial blood pressureis a major cause of prematurevascular disease leading to
cerebrovascular eventsischaemic heart disease and peripheral vascular disease
892019 02 Systemic Hypertension
httpslidepdfcomreaderfull02-systemic-hypertension 467
Blood pressure is the pressure exerted bythe blood against the walls of the bloodvessels especially the arteries
It varies with the strength of the heartbeatthe elasticity of the arterial walls thevolume and viscosity of the blood
and a persons health age and physical

The prevalence
hypertensions is higher among blacamps and
older persons especially older women
Hypertension increased with age and is
higher in young men than in young
women
although the reverse is true in older
adults

efinition of Circadian Rytm
9ircadian rhythms are daily cycles of
physiology and behavior that are driven by
an endogenous oscillator with a period of
approximately one day
892019 02 Systemic Hypertension
httpslidepdfcomreaderfull02-systemic-hypertension 1967
Norally circadian rhyths
are synchroniCed with the 3 h
environment by stimuli which alter the
phase of the underlying brain circadian pacemaamper
or most organisms including mammalsthe primary phaseshifting stimulus is light
892019 02 Systemic Hypertension
httpslidepdfcomreaderfull02-systemic-hypertension 2067
hese processes include
sleepwaampe cycles
body temperature
blood pressure
release of hormones
his activity is controlled by the biologicalclocamp which is located in the suprachiasmtic nuclei of the hypothalamus inhuman brains
It is highly influenced by natural daramplightcycles but will persist under constantenvironmental conditions ExamplesDisruptions to the circadian rhythm cancause problems with the sleepwaampe cycle
892019 02 Systemic Hypertension
httpslidepdfcomreaderfull02-systemic-hypertension 2167
9ircadian rhythms are regulated by threecomponents
+) the circadian pacemaamper or clocamp
3) an input mechanism which allows theclocamp to be reset by environmental stimuliand
)an output mechanism which regulates physiological and behavioral 2rocesses
