MrsD,
I learned that the hard way.

I told the trainer that it should be asked of all people who worked out at the hospital health plex. A lot of cardiac patients used the facility, but I am sure they were informed.

I don't think I am a dummy, but I had no clue that the BB would lower my BP.

I know now how dangerous that can be and we set a new target rate for me.
Thanks,
Judy
