Hi QDM,
No specific problem was stated, just that Q/Qs waves were inferior !
I actually found a a 4 year old ECG trace in some old med records and there is a slight difference between it and the present one on the the trace marked III. The wave drops slightly below the ref (horizontal) line whereas on the 4 year old one most of the variation appears above the line. Is this the Q/QS wave I wonder?
I really don't have any idea what I'm looking at so I'm trying not to read too much into it.
cheers
