cardio system in health diseases 5 Flashcards
name the 2 periods that the cardiac cycle consists of
systole: contraction and emptying
Diastole: relaxation and filling
how does diastole vary at rest compared at exercise
it is muhc longer at rest
lable the structure
the valves and the chambers artery/ veins
explain this picture
lable and explain the diagram
explain this picture compare ECG/ pressure/ volume
mentions what happens in mid diastole- pressure and P/A valves
mentions what happens at late diastole- P wave…
what happens at QRS complex
what is isometric phase/ isovolume metric phase.
when both semi lunar valves are shut along side AV valves are shut so there is moment of blood.
what is isovolumetric ventricular relaxation ?
when the AV vales are losed and the relaxed ventricles
explain ejection period - ventricle pressuer. valves open. blood movement. aortic pressure
describ what happens at the T wave.
ventricle pressure and what valves are open/ shut
what is Dicrotic notch
the riase in pressure flowing a decrease in pressure in the aorta
what happens in the fillin period:
ventricle/ atrium pressure and volume . what valves open
what are the major 5 phases of the cardiac cycle?
- Filling period
- atrial contraction
- isovolumentric ventricular contraction
- ejection
- isovolumetric relaxation
what is phonocardioagram used for
detecting heart sounds
there are 2 heart sounds what does 1 and 2 coincide with ?
- begining of systole as AV valves close
- onset of diastole as aortic/ pulmonary valves close
what is a murmur
abornal sounds in pathological conditions
