anatomy Flashcards
identify
A right atrium
B left atrium
C aortic knuckle
what does bundle of HIS split into
L and R bundle branches either side of interventricular septum
what 3 things make up cardiac plexus
vagus
sympathetic
general visceral afferents
where does cardiac plexus go into heart
SAN
which symp nerves in cardiac plexus
T1-T5
what do GVA nerves travel with
sympathetic nerves
where is cardiac pain perceived
T1-T5 dermatomes more or less
Why is LCA stenosis less serious in R dominant heart
because interventricular septum gets blood from both R AND L coronary arteries
where does Inter ventric septum get blood in L dominat heart
PDA only which is branch of L circumflex
2 signs of bundle branch block
prolonged QRS complex
loss of ventricular synchrony
how to identify LAD on angiogram
goes towards apex
3 most common regions of CA stenosis
top of LAD
top of L circ
Top of R CA
what is angioplasty
balloon catheter + stent
which artery used commonly for coronary bypass
internal thoracic
which CA is occluded
LAD
which are systolic murmers
mitral regurgitation and aortic stenosis
which are diastolic murmurs
mitral stenosis and aortic regurgitation
how can you see LA enlargement on chest xray
doubledensity
what do GVA transmit
chemical and bp, pain
Branches of LCA
LAD (anterior interventricular) and circumflex
Branches of RCA
marginal and posterior interventricular
circumflex supplies
l atrium
side and back of l ventricle
LAD supplies
front and bottom of l ventricle
front of septum
RCA supplies
r atrium
r ventricle
bottom of both ventricles
back of septum
