Q

What is the difference between preload and after load?

A

preload: the amount of blood that’s coming to the right side of the heart, stretching the muscle as it dilates
afterload: the amount of pressure that the ventricle needs to get to to open the aortic valve

Q

why do S1 sounds get split?

A

during inspiration, when blood goes to the lungs to pick up oxygen, we inspire - it remains sequestered there for a little bit, which means we have a little less blood in the left side of the heart and more in the right side

what happens is that the aortic valve, since it has less blood, closes so the pulmonic closes after it, instead of closing together

25
What happens in S1?
the beginning of systole, which is when the ventricles contract and push blood to the pulmonary artery and through the aorta P+ A valves contract and OPEN so that the blood doesn’t go back into the atria, the mitral and tricuspid valves CLOSE
26
What happens in S2?
diastole of the ventricle aortic and pulmonic CLOSE (make the noise), tricuspid and mitral OPEN to let blood come down from the atria to the ventricles

DOE
dyspnea on exertion
29
Dyspnea
shortness of breath
30
Paroxysmal nocturnal dyspnea (PND)
sleep for a couple hours, then get up in the middle of the night and open the window to get a deeper breath for people in failure, when they lie down, it increases the volume of intrathoracic blood - it makes them feel breathless (fine when they sit up)
31
3 main signs of pulmonary edema
left-sided heart failure pink, frothy sputum fear of impending doom because of the dyspnea
32
what are heart palpitations?
when the patient is aware of their heart rate and beating, whether it’s fluttering, skipping a beat, or bounding
33
syncope (definition, causes)
passing out - the kind of fainting we associate with heart may be caused by emotional stress, pain, pooling of blood in the legs due to sudden changes in body position, overheating, dehydration, heavy sweating or exhaustion
34
when does edema get worse
in the evening because it’s more dependent
35
nocturia
fluid resorption and secretion during evening hours

means they have edema everywhere (sacral, arms, legs, face) - everything shows they’re having leakage of fluid into the interstitial spaces can happen with kidney failure but also liver and heart
37
central cyanosis
skin turning blue or ashen all over -- caused by decreased pulmonary venous saturation
38
peripheral cyanosis
only certain areas, usually around the mouth (perioral cyanosis), etc. decreased cardiac output or reduce rate of blood flow through capillaries and increased local extraction of oxygen can be caused by congestive heart failure, shock
39
Hemoptysis
coughing up of blood
40
what is the most common cardiac reason for Hemoptysis?
mitral valve stenosis (due to increased pulmonary venous congestion)
41
When taking blood pressure in both arms, there should be no more than ____ difference on either side

Pressure generated by blood remaining in arterial tree during diastole, when the ventricles are relaxed
44
Orthostatic hypotension often seen in what 3 kinds of patients?
Parkinson’s patients who are receiving hypertensive meds patients who complain of lightheadedness
45
What is Orthostatic hypotension?
changing from supine to standing, systolic decreases no more than 15 mm Hg- heart rate increases up to 10 beats/min
46
What is orthostatic hypotension caused by?
vascular volume loss from hemorrhage, diarrhea, vomiting, dehydration or excessive diuresis Redistribution of blood volume because of antihypertensives (affect preload, affect afterload), antidepressant, alcohol or nitrates Prolonged bed rest, simple vasovagal fainting autonomic nervous system dysfunction in diabetic neuropathy, adrenal insufficiency or Parkinson’s disease
47
3 kinds of upstroke when palpating the carotid arteries
Brisk – normal diminished – feels small and weak (decreased stroke volume - might be hypervolemic) Bounding – feels full and strong (did they just exercise or run to the office? otherwise is hyperkinetic states - hyperthyroidism)

62
What is S2, which valves open and close during S2, and where is it heard the loudest?
S2 is diastole Aortic and pulmonic are closing (makes the sound), and the tricuspid and mitral are opening (silent) heard loudest at the base

True or false: At the 3rd intercostal space, S1 and S2 have the same intensity of sound?
True
64
When can a split S2 only happen?
during inspiration
65
S3: ventricular gallop
kind of sounds like the word “kentucky” (tap-tap-tap, tap-tap-tap) or distant thunder usually means that someone is in congestive heart failure - it’s one of the first signs - it occurs both lying down and sitting up in this case (pathological) can happen normally, to children or with a large cardiac output in pregnancy
66
S4: atrial gallop
kind of sounds like the word “tennessee” (luuub-dub-dub) can occur in athletes, but mostly pathological, and it normally means very low compliance in the ventricles either from CHF, aortic stenosis you’ll hear these mostly in the left ventricle because it’s the higher
