The ECG Flashcards
1
Q
How does a pathological Q wave look?
A
Q wave extends deeper down than usual
2
Q
Why does a Q wave form?
A
The area of muscle affected by the infarction will act like a window for the lead. Therefore the lead will have a closer/clearer view of the depolarisation of the septum heading away from itself so form a larger downward deflection.
