Subject: valvular incompetence

I was wondering if I can get everybody's input regarding valvular
reflux.
There is some confusion regarding reflux criteria. I am especially
interested in the sustained time period that is considered reflux. I am

hearing anything greater than a second up to 3 seconds. I am also being

asked by the vascular physicians if the patient's reflux is mild,
moderate
and severe. Is there any criteria out there that can answere this?
Your input is appreciated.
Thanks
