I'm sorry your wife is experiencing panic attacks. I know how scary they can be. I've had one before. I've heard either through people or through the abnormal psych class that the worst thing about these attacks is that the person begins to fear that they will have another one. Then they stop going outside the home and if that continues long enough they start actually fearing going outside.
I've heard the best thing to do is to allow the panic attack to happen, breathe through it, and let it run it's course. That if you try to fight it, it just gets worse and lasts longer and happens more frequently.
Perhaps she could DB her panic attacks? Figure out what makes them shorter, less intense?
Maybe call a DB coach on this one to get some techniques?
