I have an abnormal ECG. Something to do with a Q wave in 111.

Resolved Question:

I have an abnormal ECG. Something to do with a Q wave in 111. My Heart Doctor has checked for possible heart attack and found none. I am 63, heart rate 54, (always has been low) and have a small amount of plaque buidup. Should I be concerned about the Q wave situation.

Do you mean you have a Q wave in lead III (Roman numeral 3)?
Customer: replied 7 years ago.
yes.
Expert:  Dr. Sophie :: Medicine & Neurology replied 7 years ago.
If your Q wave is isolated to lead III it is likely a benign Q wave. If there were Q waves in adjacent leads this would probably be something serious. Sounds like your heart specialist did not want to put everything on EKG and tested you just to be safe.


Another way to look at the heart is to do a 2D Echocardiogram and to look at heart wall motion abnormalties which may be consitent with previous heart attack. Your doctor was probably not concerned about it after your other tests came back OK.

What causes the benine Q wave situation in lead 3?
Expert:  Dr. Sophie :: Medicine & Neurology replied 7 years ago.
A small electrical impulse directed away from the lead causes a small Q wave in that lead. Isolated Q waves are usually narrow (unlike pathologic ones) and small.
