1. right side of the heart has ANS >> deoxygenated blood
2. left side of the heart has ANS >> oxygenated blood
3. What are early signs of hypoxia? ANS >> Restlessness, headache, fatigue, SOB.
4. the ventricles with blood during diastole ANS >> fill
5. the ventricles with blood during systole ANS >> empty
6. stroke volume ANS >> The volume of blood ejected from the ventricles during systole
7. sterlings law ANS >> As the myocardium stretches, the strength of the subsequent contraction increases
8. S1 heart sound "Lub" ANS >> mitral and tricuspid valves close

, needs
of the body
15. preload ANS >> The amount of blood in the left ventricle at the end of diastole, often referred to as end-
diastolic volume.
16. afterload ANS >> Resistance to left ventricular ejection
17. myocardial contractility ANS >> The ability of the heart muscle to contract.
18. what can affect myocardial contractility ANS >> o Injury to the myocardial muscle such as an
acute MI
causes a decrease in myocardial contractility.
o The myocardium of the older adult is stitter with a slower ventricular filling rate and prolonged contraction time.
19. where should electrical impulses originate from ANS >> SA node (if they don't start in the
SA node it can cause conduction disturbances)
20. dysrhythmias ANS >> Rhythm disturbances, meaning a deviation from the normal sinus heart rhythm
21. tachycardia ANS >> greater than 100 bpm (fast HR)
22. bradycardia ANS >> less than 60 bpm (slow HR)
23. Tachydysrhythmias and bradydysrhythmias lower... ANS >> cardiac output and blood
pressure.
24. atrial fibrillation ANS >> rapid, random, inettective contractions of the atrium "quivering"
25. Paroxysmal supraventricular tachycardia ANS >> A sudden, rapid onset of tachycardia
