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

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
