Q wave

Posted by Bev on April 22, 1999 at 13:03:04
I have asked you questions previously regarding my ten year old daughter.  She has repaired ALCAPA.  On her latest ECG nonspecific ST and T wave changes continue to be noted.  A deep and wide Q wave in aVL is a new finding.  She has normal sinus rhythm with sinus arrhythmia.  A follow-up Holter monitor noted bradycardia and tach, also her usual PVCs and PACs.  What does the Q wave in aVL measure and what types of changes could the new finding signify?

Dear Bev, thank you for your question.  Most likely, the q wave in AVL is an incidental finding.   I suggest that you speak with your daughter's physician who could compare old and current ECG's to confirm the presence of a q wave in AVL and to determine the significance of this new ECG finding.
