Question | Answer |
---|---|
acute chest pain that occurs when myocardial demand exceeds its oxygen supply | Angina pectoris |
(aortic insufficiency) incompetent aortic valve that allows backward flow of blood into left ventricle during diastole | Aortic regurgitation |
calcification of aortic valve cusps that restricts forward flow of blood during diastole | Aortic stenosis |
bulbous enlargement of distal phalanges of fingers and toes that occurs with chronic cyanotic heart and lung conditions | Clubbing |
severe narrowing of the descending aorta, a congenital heart defect | Coarctation of aorta |
right ventricular hypertrophy and heart failure due to pulmonary hypertension | Cor pulmonale |
dusky blue mottling of the skin and musous membranes due to excessive amount of reduced hemoglobin in the blood | Cyanosis |
difficult labored breathing | Dyspnea |
LVH (left ventricular hypertrophy) | increase in thickness of myocardial wall that occurs when the heart pumps against chronic outflow obstruction (ex. aortic stenosis) |
(mitral insufficiency) incomptent mitral valve allows regurgitation of blood back into left atrium during systole | Mitral regurgitation |
calcified mitral valve impedes forward flow of blood into left ventricle during diastole | Mitral Stenosis |
uncomfortable awareness of rapid or irregular heart rate | Palpitation |
opposite of a normal split S2 so that the split is heard in expiration, and in inspiration the sounds fuse to one sound | Paradoxical splitting |
high-pitched scratchy extracardiac sound heard when the precordium is inflamed | Pericardial friction rub |
normal variation in S2 heard as two separate components during inspiration | Physiological splitting |
(pulmonic insufficiency) backflow of blood through incompetent pulmonic valve into the right ventricle | Pulmonic regurgitation |
calcification of pulmonic valve that restricts forward flow of blood during systole | Pulmonic stenosis |
abnormal mid-diastolic heart sound heard when both the pathologic S3 and S4 are present | Summation gallop |
temporary loss of consciousness due to decreased cerebral blood flow (fainting), caused by ventricular asystole, pronounced bradycardia, or ventricular fibrillation | Syncope |
palpable vibration on the chest wall accompanying severe heart murmur | Thrill |
