Hi, I am a 31 years old woman and never had a problem with heart, today, when I was cycling to work, I felt I almost had
heart stop... while I was cycling the weather was very
cold and I couldn't almost feel my fingers any more, even though I had gloves. when I reached work after just 11 min cycling, I barely could stand, I got very low blod pressure and my college said, my face was very dark color when she saw me laying on corridor. My fingers had as well very dark color.
