Why do I become short of breath when my heart-rate increases even if said increase is not due to increased physical exertion or activity?
I exercise daily and do not think this is due to deconditioning but a hot bath, upsetting news or other sedentary situations that increase my heart-rate seem to bring on breathing difficulties even with high O2 saturation.
I am breathing slowly and exhaling completely so I don't think this is an air-trapping situation. With bathing, the breathing problems don't get bad till I get out of the bath. I noticed my heart-rate (usually 75-95) is up around 125
My FEV1 is 18% I am underweight with emphysema
