the heart Flashcards
1
Q
- abnormally rapid heart rate
- heart rate greater than 100 bpm
A
tachycardia
2
Q
- conveys heart sounds to examiner’s ear
- can detect a murmur
A
3
Q
- abnormally slow heart rate
- less than 60 bpm
A
4
Q
- a heart sound resulting from ventricular filling
- considered normal
A
5
Q
increased heart rate
A
6
Q
- impulses travelling from SA node to AV node
- SA node-Bundle of His-Purkinje Fibers
A
7
Q
- in the SA node in upper wall of RT atrium
- sets the rate of contractions
A
8
Q
factors contributing to cardiac output
A
stroke volume ((SV) the volume of blood ejected from each ventricle with each contraction) x Heart Rate (HR)
9
Q
heart parts contracting during systole and diastole
A
- ventricles contract during systole
- atrial diastole (relaxation) begins at the same time as ventricular contraction begins
10
Q
the blood vessels in the myocardium
A
11
Q
the dilated vein that returns blood from the coronary circulation to the RT atrium
A
12
Q
are the Aortic (between the LT ventricle and aorta) and the Pulmonary (between the RT ventricle and the pulmonary trunk)
A
13
Q
is in between the RT atrium and ventricle
A
14
Q
in between two upper chambers of the heart
A
15
Q
chambers of the heart
A
- upper = atrium
- lower = ventricle
