A few months ago I started having problems breathing and thought I was getting bronchitis. I already had a runny nose. I get it just about every yr. and I have asthma. We don't have ins. so I just took over the counter meds and waited for it to run its course. About a week and a half later I still was not feeling better, actually worse so my DH took me to the hospital. they listened to my heart and lungs and immediately took me back to be seen. My heartrate was 150. What I thought was bronchitis was a flutter in my heart which could have caused a multiple of other problems including stroke, because it causes clots. Luckily after 4 days in the hospital they sent me home on meds for my heart and I will be fine.
