I’m a 70 year old female who has been experiencing really bad wheezing since about last October, it got worse so in February I went to my GP and, after blood tests and a chest CT scan showed no reason for this he referred me to a cardiologist for an echocardiogram and a consult. I finally had that appoinment today and it showed no problem with my heart which, while reassuring, does not really help. My wheezing comes and goes, sometimes is really bad for weeks at a time even when I’m just sitting reading a book or watching tv, on some occasions I’ve got super hot and felt like I was going to pass out, other times it’s like someone has flicked a switch and I’m perfectly okay for a few weeks. The cardiologist was as mystified as I am, his suggestion is that I purchase an electronic gadget that I would use to get a EKG reading when I’m having the wheezing then email it to him. He says it could be an arrhythmia or Atrial Fibrillation but without actually seeing the reading while it’s happening there’s nothing he can do. I have NO palpitations or chest pain and my BP, heart rate and oxygen level remain perfectly normal on the days I’m wheezing bad. I’m just wondering if anyone else has this same problem and what the outcome was.
