I don't understand when the RO said he could stop the radiation to give atropine. The only time your husband is under propofol is when they do the procedure to insert the catheter. (At least that's how it was with me.) He's awake during the actual radiation, correct? Which also isn't very long.
Can you post your husband's stats? I'm curious at to what risk group he's in. As to is one HDR session enough, I would think that as long as they can adjust on the EBRT side of the equation that he would probably get a sufficient dose of radiation. At least that's what the RO seems to be telling you.
EDIT: After posting this I saw your additional posts with Dan's stats. As a Gleason 7, I think there's less worry than if he was in the high risk group. I think it all depends on what the chances are of a major heart issue. Remember, most intermediate risk PCa is curable, but a heart issue can be...well, worse. Maybe have your cardiologist and the RO discuss together?
