Hi,
I have hypertrophic cardiomyopathy and currently, under metoprolol succinate 50 mg extended release tablets (once daily) for the past one year. Now a days, when I stand up after 5 minutes of squatting position, I feel a sudden giddiness for two to three seconds. During that time, I am looking for a support (like wall) to hold to stabilize myself. And then, during that time, my breathing goes little deep for sometime; I am losing my eye sight for two seconds and I feel a crushing feeling in my head. Is it an emergency? Should I get an immediate treatment?
