Seen a couple of posts on this but wondered if anyone had gotten to the bottom of it. I get a sudden involuntary sharp intake of breath. Can happen any time and always takes me by surprise. It doesn’t happen often and isn’t worrisome, but just curious as to what the cause is. I’m on Clopidogrel and Bisoprolol following OHS in January. Not sure if it’s meds related, surgery related or something else. Any ideas?
