the base of the heart is ?? | @ the top |
the Apex of the heart is ? | @ the bottom |
apical impulse is located ? | @ the apex of the heart |
S1 = | blood into ventricles, p increases, av valves close |
systole | ventricles contract |
semilunar valves open allowing blood where? | pulmonary artery and aorta |
S2 = | p - semilunar valves close |
diastole= | ventricles relax |
co cardiac out put = | stroke volume sv x heart rate hr |
if co is decreASED what happens to the pulse? | @ first pulse will decrease than the pulse will increase to try to compensate |
ventricle preassure rises = | systole |
systole = increase in preassure = | AV valves close |
ventricles contract during | systole |
LV ejects blood to | body |
Rv ejects blood to | lungs |
Systole known as | S1 or lub |
ventricles relax while atria contract = | diastole |
When preassure in ventricles < aorta and pulmonary attery = | diastole |
known as S2 or Dub | Diastole |
Occasionally hear third sound while ventricles fill = | S3 |
Is an S3 sound normal ? | Younger = normal growth spurts older = pathologic |
Preassure in L side of heart > where | right side of heart |
While assessing a client what would u want 2 know about their history | diet, exercise, cholesterol, HTN, diabetes, gender, stress, heart trouble, Palpitations, dyspnea, orthopnea, edema, fatique, chest pain (coldspa) medication |
dyspnea | Dyspnea (Latin dyspnoea, Greek dyspnoia from dyspnoos - short of breath) or shortness of breath (SOB) is perceived difficulty breathing or pain on breathing. It is a common symptom of numerous medical disorders. |
orthopnea | Discomfort in breathing that is relieved by sitting or standing in an erect position. |
History pacemaker | A part of the body, such as the specialized mass of cardiac muscle fibers of the sinoatrial node, that sets the pace or rhythm of physiological activity. |
automatic internal defibrillato | pacemaker |
split S2 = | Preassure in L side of heart > right side occasionally hear aortic valve close prior to pulmonic valve |
Type of info to find out about the heart while taking a health history | Pacemaker, AID, |
Type of info to find out about the heart while taking a past health health history | diabetes, dependent edema, congenital heart defect, CAD, rheumatic fever, ECG when? any other diagnosis, |
