Supplies Right atria, | | |
anterior and | |
posterior right ventricle, | | |
SA & AV
| | |
nodes Bundle of His.
| | |
Subendocardial or non-Q wave Infarction - CORRECT ANSWER✔✔-Involves layer
| | | | | | | | |
below the endocardium.
| |
Damage is starting from within the heart and moving outward but hasn't gone
| | | | | | | | | | | | |
into the endocardium yet
| | |

| | | | | | | | | |
all
|
layers/wall of the heart | | |
