Ischemia
What does symmetrical T wave inversion indicate?
Ischemia
How do you determine injury to the heart muscle in an area of the heart?
ST segment elevation of 1 mm or more in any two anatomically contiguous leads in the lead group corresponding to that area.
What is indicated by elevation in
Il, IlI, AvF?

What is indicated by elevation in
V1, V2?
Septal wall infarction
What is indicated by elevation in
V3, V4?

What is indicated by elevation in
V5, V6, I, AvL?
Lateral wall infarction (circumflex)
What is indicated by elevation in
V8, V9?
That’s a fifteen lead
