Sleeping pill that causes irregular heart beat........ for someone with congestive heart failure???

I'm not too sure about the doctor that saw my dad the other day. My dad has a odd sleep pattern, always has had an odd sleep pattern it goes back to when he programmed computers for a living and would be called in at all hours of the day and night to fix a messed up program (back before they had the fancy restore features and boot disks).

Well, this doctor prescribed dad Ambien, which is a sleep aid. This is good, no problem, until you look at the instructions that came with it and see that a major side effect is an unsteady heart beat.

Wait... Unsteady heart beat? You have a man in his 70's that you just said has congestive heart failure and you want to give him a sleeping pill that causes unsteady heart rates?

Needless to say I am waiting to see what my dad's regular doctor says about it before I follow any such advice from the doctor that wanted my mom to sign paperwork saying she wanted them to sit on their thumbs if dad had a heart attack. The same guy that told her to not call 911 and just let it happen if dad had a heart attack.

Still grrrring at what I was told about that doctor's idea of helping patients.
