Cards in this set: 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.
