Cards

Term
Precordium
Definition
the area on the anterior chest overlying the heart and great vessels. the great vessels are themajor arteries and veins connected to the heart.
Term
Mediastinum
Definition
where the heart and the great vessels are located between the lungs in the midle third of the thoracic cage
Term
Apex
Definition
the bottom of the heart, and you are hearing this part of the heart when listening to apical pulse
Term
Base
Definition
top of the heart
Term
The great vessels
Definition
lie bunched above the base of the heart.
Term
Superior and inferior vena cava
Definition
return unoxygenated venous blood to the right side of the heart
Term
Pulmonary artery and Vein
Definition
this artery leaves the right ventricle, bifurcates, and carries the veonous blood to the lungs. This vein returns the freshly oxygenated blood to the left side of the heart
Term
Aorta
Definition
carried oxygenated blood out of the body
Term
Pericardium
Definition
tough, fibrous, double-walled sac that surrounds and protects the heart
Term
Myocardium
Definition
The muscular wall of ht eheart, it does the pumping
Term
Endocardium
Definition
think layer of endothelial tissue that lines the inner surface of the heart chambers and valves
Term
What side of the heart pumps blood to the lungs and what side pumps it to the body?
Definition

Right side Lungs

Left side heart

Term
atrium
Definition
thin-walled reservoir for holding blood
Term
ventricle
Definition
thick-walled is the muscular pumping chamber
Term
what are the 4 chambers of the heart?
Definition
right atrium, left atrium, right ventricle, left ventricle
Term

What are the 4 valves of the heart?

 

Definition

Atrioventricular valves separates the atria and the ventricles, the right AV valve is the Tricuspid and the left AV valve is the bicuspid or mitral

 

Semilunar valves are set between the ventricles and the arteries. the SL vavles are the pulmonic on the right side, and the aortic on the left side

Term
When do the AV valves open, and when do the SL valves open?
Definition
open during diastole, open during systole
Term
Diastole of the heart
Definition
ventricles relax and fill with blood. Takes up 2/3 of the cardiac cycle. AV valves are open, the pressure in the atria is higher than in the ventricles so blood pours rapidly into the ventricles.
Term
systole of the heart
Definition
blood is pumped fromthe ventricles and fills the pulmonary and systemic arteries. this is 1/3 of the cardiac cycle. ventricular pressure is finally higher than that in the atria, so the mitral and ricuspid valves swing shut. AV valves close and prevent regurgitation of blood back up into the atria.
Term
First heart sound (S1)
Definition

occurs with closure of the AV valves and thus signals the beginning of systole. usually heard loudest at the apex.

S1 is lounder than S2 at the apex

S1 coincides with Rwave on electrocardiogram

Term
Second heart sounds (S2)
Definition
occurs with closure of the semilunar valves and signals the end of systole.
Term
effects of Respiration
Definition

during inspiration intrathoracic pressure is decreased. increasing venous return to the right side of the heart, wihc increases right ventricular stroke volume.

 

on the left side, a greata amount of bllood is sequestered in the lungs durning inspiration. momentarily decreases the amount returned to the left side of the heart decreasing left ventricular stroe volume

remember: MoRe to the Right heart, Less to the Left heart.

Term
S3
Definition
occurs when the entricles are resistant to filling during the early rapid filling phase. occurs immediately after S2 when the AV vales open and atrial blood first pours into the ventricles. Sounds like a vibration
Term
S4
Definition
occurs at the end of diastole, when the ventricle is resistant to filling. also creates vibrations and occurs just before S1
Term
condtions resulting in a murmur
Definition
  1. Velocity of blood increases
  2. viscosity of blood decreases
  3. structural defects in the valves
Term
murmur
Definition
gentle, blowing, swooshing sound that can be heard on the chest wall.
Term
Heart sounds
Definition

1. fequency (pitch)

2.intensity (loudness)

3.Duration-very short for heart sounds, silent periods are longer

4. timing- systole or diastole

 

Term
How many liters of blood per minute does the body pump throught the body?
Definition
4 to 6 L
Term
cardiac output
Definition
strock volume times the number of beats per minute
Term
preload
Definition
venous return that builds during diastole. it is the length to which the ventricular muscle is tretched at the end of diastole just before contraction. the greater the stretch the stronger heart contracrtion
Term
afterload
Definition
opposing pressure the ventricoels must generate to opeen the aoric valve against the higher aortic pressure.
Term
Carotid artery
Definition
central artery, located in the groove between the trachea and the sternomastoid muscle, medial to and alongside the muscle.
Term
Jugular vein
Definition
empty unoxygenated blood directly into the superior vena cava. gives info about the activity on the right side of the heart.
Term
Subjective data of patient
Definition

chest pain- any chest pain or tightnesss?

dyspnea: any shortness of breath?

orthophnea: how many pillows do you sleep with?

cough: do you have a cough?

fatigue: do you seem to tire easily?

edema: any swelling of your feet?

 

Term
objective data of patient
Definition

carotid arteries- palpate ausculatate for bruit

jugular veins- inspect the pulse, estimate the venous pressure

precordium- inspect the anterior chest, palpate the apical impulse, palpate across the percordium

Identify S1 and S2

Term
Auscultation- areas where you listen
Definition

second right interspace- aotic valve area

second left interspace-pulmonic valve area

left lower sternal boarder-tricuspid valve area

fifth interspace at around left midclavicular line-  mitral valve area

Term
splitting of S2
Definition
this is a normal phenomenon that occurs towars the end of inspiration in some people. instead of one DUP you hear a split sounds T-DUP. heard only in the pulmonic valve area, the second left interspace
Term
Midsystolic click
Definition
althought this is systolic it is not an ejection click. it is associated with mitral valve prolapse in which  the mitral valve leaflets not only close with contractino but ballow back up into the left atrium. Short high pitch
Term
ejection click
Definition
early in systole at the start of ejection beacuase it results from opening of the semilunar valves. short high pitch, with a click quality, and heard best with the diaphram
Term
aortic prosthetic valve sounds
Definition
sequela of modern technologic intervention of heart problems. ball-in-cage
Term
opening snap
Definition
presence of stenosis increasingly higher atrial pressure is required to open the valve. so deform valve opens with a noise. it is sharp and high pitched
Term
summation sound
Definition
when both the S3 and S4 are present, a quadruple rhythm is heard
Term
pericardial friction Rub
Definition
inflammation of the precordium gives rise to this. the sound is high pitched and scratchy like sandpaper. its best heard with diaphram
Term
Thrill at the base
Definition
in the second and third right interspace occurs with sever aortic stenosis an systemic hypertension. takes more pressure to pump it up
Term
Lift (heave) at the sternal border
Definition
occurs with right ventriclar hypertrophy, as found in pulmonic valve disease, pulmonic hypertension
Term
atrial septal defect
Definition
abnormal opening in the atrial septum, resulting usually in left to right shunt and causing alrge increase in pulmonary blood flow
Term
Ventricluar septal defect
Definition
abnormal opening in septum between  the ventricles, usually subaortic area. the size and exact postion vary considerably
