N112 Heart

acute chest pain that occurs when myocardial demand exceeds its oxygen supply

(aortic insufficiency) incompetent aortic valve that allows backward flow of blood into left ventricle during diastole

calcification of aortic valve cusps that restricts forward flow of blood during systole

the left semilunar valve separating the left ventricle and the aorta

tip of the heart pointing down toward the 5th intercostal space

point of maximal impulse, (PMI) pulsation created as the left ventricle rotates against the chest wall during systole, normally at the 5th left intercostalspace in the midclavicular line

broader area of hearts outline located at the 3rd right and left intercostal space

severe narrowing of the descending aorta, a congenital heart defect

right ventricular hypertrophy and heart failure due to pulmonary hypertension

the addition of a 3rd and 4th heart sound makes the rhythm sound like the cadence of a galloping horse
