My asthma has been flaring up the past few days. When I was still in bed earlier, I was feeling pretty bad in terms of my symptoms. However, my heart rate was actually much lower than it is normally. That seemed really backwards, and I don't really know what to think. My oxygen saturation was at 92%, so not really bad, but does seem to support that I'm not just imagining the flare. Have you ever heard of this happening? I thought asthma attacks always caused increased heart rate, so I'm confused.
