From this, my stroke volume
is 125 x 0,57 = 71 ml and CO at heart
rate 80 = 5,7 l/hour?
If my heart
rate increases to 200, my CO is 14,2l/hour. Anyway, I guess my EF increases a bit during heavy exercise (mid to upper range heart rate), and reduces if HR is too high, like the torque on an engine, right?
A strange thing was, during my echocardiography, I was very scared and I felt this light, but somewhat elevated heart rate (100-120), possibly lowering EF?
