The correct answer is stronger emotions and a faster heart rate
The beat rate of a normal rested heart is 60 to 100 per minute. The atria (the two smallest chambers of the heart) contract simultaneously, and the same happens shortly thereafter with the ventricles (the two largest chambers).
This mechanism causes the characteristic “double beat” of the heart: tum-ok, tum-ok… Exercises or emotional stress can increase the heart rate to up to 200 or more pulsations. In people with a healthy heart, when the demand for effort returns to normal, the heart rate also restores quickly.
