I suppose it depends on the software. You and I know that there are many,
often innocuous, reasons for Q-waves:
Septal Q-waves in leads V5 and V6
A normal variant in lead III
In left bundle branch block in leads V1 and V2
These are just the common ones; others include PE, WPW syndrome, even left
posterior hemiblock. I hasten to add, I don't believe I've ever seen the
latter, so my internal software might struggle a bit if confronted with it!
I have noticed that these ECG machines are set up to be overly sensitive, I
suppose there is a certain logic in that approach.
