With respect to the question "is it safe to use QRO if I have a pacemaker?",
the necessary assertion isn't "some QRO ops with
pacemakers have not experience device failure", but rather "no QRO ops with the
pacemaker you're considering will experience device
failure". Thus reports of the form "I know 3 QRO ops with pacemakers, and
they're all fine" are not helpful. Only the company that
makes the pacemaker model you're going to have implanted can tell you
- whether that unit was designed to withstand the fields produced by QRO HF
amplifiers
- how they evaluated the design for its ability to tolerate QRO-generated
fields without malfunction
- how they test manufactured units for compliance with design objectives
As others here have suggested, contact the manufacturer's engineering
department. Ask the above questions. If they aren't happy to
provide answers, consider another manufacturer.
