Hello - I Have A Real Big Concern With My

Hello - I have a real big concern with my mother. A little bit about her history, she's had a heart attack, a stroke about 5 months ago, a stint in her heart. I'm not sure about all the medications she's on but I know it is a lot. She had an episode two weeks ago tonight, she broke out in a heavy sweat an my father in law got her to the bed, she was out, 911 was called and she was taken to the hospital. So far all of her heart test have come back good. However, Monday she is going on a 28 day heart monitor for more testing. She's on Chantix, she nausious often, tired, weak and the Dr's seem to think that she is having seizures or mini strokes. I'm thinking with all of her meds and adding Chantix to the mix is what might be causing these seizures (not convulsive) or mini strokes. Can you help?
