Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, you should
consult cardiologist for her because possibility of heart related diseases is more in her case.
Sudden onset breathlessness, choking,
unconsciousness etc are characteristic symptoms of end stage heart diseases like
heart failure, coronary artery disease,
hypotension etc.
So better to consult cardiologist and get done
1. Blood pressure monitoring
2. Ecg
3. 2d echo
4. Coronary
angiography.
She may need cardiac supportive drugs.
Don't worry, with appropriate treatment, she will be alright.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your mother. Thanks.
