Cards

Term
systole
Definition
ventricular contraction
Term
diastole
Definition
ventricular relaxation
Term
cardiac cycle
Definition
one complet heartbeat, during which both atria and ventricles contract and then relax
Term
dicrotic notch
Definition
an elastic recoil of the aorta after valve closure
Term
murmurs
Definition
abnormal heart sounds, often indicate valvular problems. In valves that do not close tightly, closure is followed by a swishing sound due to the backflow of blood.
Term
pulse
Definition
the alternating surges of pressure in an artery that occur with each contraction and relaxation of the left ventricle
Term
pulse pressure
Definition
difference between systolic and diastolic pressure
Term
common carotid artery
Definition
side of neck
Term
temporal artery
Definition
anterior to the ear, in the temple region
Term
facial artery
Definition
clench the teech and palpate the pulse just anterior to the masseter muscle on the mandible
Term
brachial artery
Definition
antecubital fossa, where it bifurcates into the radial and ulnar arteries
Term
radial artery
Definition
at the side of the wrist
Term
femoral artery
Definition
in the groin
Term
popliteal artery
Definition
back of knee
Term
posterior tibial arty
Definition
just above the medial malleolus
Term
dorasalis pedis artery
Definition
on the dorsum of the foot
Term
apical pulse
Definition
the counting of the heart beats
Term
pulse deficit
Definition
any large difference between the values observed, may indicate cardiac impairment: a weekend hart that is unable to pump blood into the arterial tree to a normal extent
Term
Blood Pressure
Definition
the pressure the blood exerts angainst any unit area of the blood vessel walls, and it is generally measured in the arteries
Term
systolic pressure
Definition
pressue in arteries at peak of ventricular ejection
Term
diastolic pressure
Definition
the pressure during ventricular relaxation
Term
sphygmomanometer
Definition
bp cuff
Term
sound of korotkoff
Definition
characteristic sounds which indicate the resumption of blood flow into the forearm
Term
pulse pressure
Definition
the difference between the systolic and iastolic pressures and the amount of blood forced from the heart during systole, or the actual working pressure. A narrowed pulse pressure (<30mmHg) may be a signal of severe aortic stenosis, constrictive pericarditis, or tachycardia. A widened pulse pressure (>40mmHg) is common in hypertensive indviduals
Term
havard step tests
Definition
tests the relative fitness level using exercise and heart tests.
Term
cold pressor test
Definition
tests the effect of emotions and pain on BP
Term
byporeactors
Definition
(stable) exhibit a rise of diastolic and or systolic pressure ranging from 0 to 22mmHg or a drop in pressures
(labile blood pressure) exhibit a rise of 23mm Hg or more in the diastolic and or systolic blood pressure
Term
dermatographism
Definition
a condition in which the direct line of stimulation will swell quite obviously.
