3. The coronary arteries arise from the to
openings in the aorta called right and
left ostiums.
The blood then passed through the
coronary arteries to the cardiac muscle
The de oxygenated blood is returned to
the heart via a network of coronary
veins, arterioles and capillaries through
the coronary sinus to the right atrium.

5. Initial assessment is done via an ECG
The ECG can tell us which part of the heart
muscle is ischemic or damaged
This also corresponds with which coronary
arteries are affected
6. The right coronary artery supplies
The right ventricle, inferior and posterior wall
It also supplies the SA and AV node
7. Supplies the anterior and septal wall of the
left ventricle
8. Supplies the posterior wall
Lateral wall
Inferior wall (in 10% of the population

11. ST segment point of interest when thinking
about myocardial ischemia or injury
12. Ischemia - ST depression and T wave
inversion
Injury - ST elevation
Infarction - ST elevation
Q Wave - old infarct

15. The exchange of pottasium and sodium is
what leads to an electrical impulse
