systolic pressure


Also found in: Dictionary, Thesaurus, Legal, Acronyms, Encyclopedia, Wikipedia.

sys·tol·ic pres·sure

the intracardiac pressure during or resulting from systolic contraction of a cardiac chamber; the highest arterial blood pressure reached during any given ventricular cycle.

systolic pressure

n.
The highest arterial blood pressure reached when the ventricles are contracting.

systolic pressure

the blood pressure measured during the period of ventricular contraction (systole). In blood pressure readings, it is the higher of the two measurements.

sys·tol·ic pres·sure

(sis-tol'ik presh'ŭr)
The intracardiac pressure during or resulting from systolic contraction of a cardiac chamber; the highest arterial blood pressure reached during any given ventricular cycle.

sys·tol·ic pres·sure

(sis-tol'ik presh'ŭr)
Intracardiac pressure during or resulting from systolic contraction of a cardiac chamber; highest arterial blood pressure reached during any given ventricular cycle. Also called systolic blood pressure.

pressure

stress or strain, by compression, expansion, pull, thrust or shear.

arterial pressure
the blood pressure in the arteries.
atmospheric pressure
the pressure exerted by the atmosphere, about 15 lb per square inch (2.17 kPa) at sea level.
capillary pressure
the blood pressure in the capillaries.
central venous pressure (CVP)
see central venous pressure.
cerebrospinal pressure
the pressure of the cerebrospinal fluid, normally 100 to 150 mmHg.
diastolic pressure
the lowest pressure recorded in the arterial blood pressure cycle. Represents the minimal pressure in the left ventricle which can maintain its ejection phase. See also blood pressure.
pressure gauge
a device attached to the outlet of gas tanks to measure internal pressure which indicates the quantity of gas remaining.
pressure gradient
the rate of increase (or decrease) in the magnitude of the pressure being measured.
intracranial pressure (ICP)
see intracranial pressure.
intraocular pressure (IOP)
the pressure exerted against the outer coats by the contents of the eyeball.
pressure load
mean circulatory filling pressure
a measure of the average (arterial and venous) pressure necessary to cause filling of the circulation with blood; it varies with blood volume and is directly proportional to the rate of venous return and thus to cardiac output.
pressure natriuresis
thought to participate in regulating the volume of extracellular fluid levels when the normal neurohumoral mediators are impaired; the increase in water and sodium ion excretions which occur when blood pressure is elevated because of an increase in the circulating blood volume.
pressure necrosis
necrosis of tissue caused by exclusion of circulation by external compression, e.g. in prolonged recumbency, or due to too-tight bandage, collar, harness.
negative pressure
pressure less than that of the atmosphere.
oncotic pressure
the osmotic pressure of a colloid in solution.
osmotic pressure
the potential pressure of a solution directly related to its solute osmolar concentration; it is the maximum pressure developed by osmosis in a solution separated from another by a semipermeable membrane, i.e. the pressure that will just prevent osmosis between two such solutions.
pressure point granuloma
see pressure points (below).
pressure point pyoderma
see pressure points (below).
pressure points
parts of the body subject to pressure when the animal is recumbent, wearing harness or saddlery, or during restraint. Usually bony prominences such as the point of the hock, hip, shoulder, elbow and lateral aspects of limbs. These are predisposed to callus formation, infection pyoderma and granulomas.
positive pressure
pressure greater than that of the atmosphere.
pulse pressure
difference between systolic and diastolic pressures in arteries.
pressure receptors
e.g. the blood pressure receptors in the aortic arch and the carotid sinus.
pressure sore
decubitus ulcer.
systolic pressure
the highest reading in the arterial blood pressure cycle. A reflection of the ejection pressure of left ventricular systole, and the elasticity of the arterial system.
venous pressure
the blood pressure in the veins. See also central venous pressure.
wedge pressure
intravascular pressure as measured by a swan-ganz catheter introduced into the pulmonary artery; it permits indirect measurement of the mean left atrial pressure.
pressure wrap
bandages which apply pressure to underlying tissues; used after trauma to limit the development of edema, and in the management of lymphedema.

Similarly this study favors our findings of regression of right ventricular systolic pressure by demonstrating that the significantly increased RV functions in the study population without significant pulmonary HT, and maintained its improved function in the mid-term follow up also.
Newer dynamic means, such as systolic pressure variation, stroke volume variation, pulse pressure variation and pulse velocity variation, seem to hold much in store for clinical practice.

Characterized by elevated blood pressure, it is diagnosed when systolic pressure is greater than 140 millimeters of mercury (mm.
Systolic pressures of 140 to 159 and diastolic pressures of 90 to 99 are designated as stage 1 hypertension (high blood pressure).
Because the threshold for diagnosing hypertension varies by age, height, and gender, there are a total of 420 different diastolic and systolic pressures that determine whether a particular child has high blood pressure, said Dr.
Note the number on the dial, which is the systolic pressure.
Zipes: As people age, the systolic pressure rises and the separation between systolic and diastolic pressure widens because the arteries become stiffer.
ECHO revealed a right ventricular systolic pressure (RSVP) of 105 mm Hg.

Individuals with systolic pressure at or above 140 millimeters of mercury (mmHg) or diastolic blood pressure at or above 90 mmHg are considered to have high blood pressure, also called hypertension.
