The heart contains electrical "pacemaker" cells, which cause it to contract — producing a heartbeat. "Each cell has the ability to be the 'band leader' and [to] have everyone follow," Phillips said. In people with an irregular heartbeat, or atrial fibrillation, every cell tries to be ...

Noteworthy upgrades over previous heart-chip models include the maturity of the cells that the team developed from human induced pluripotent stem cells (hiPSCs), and its ability to beat much like a human heart – at around 60 beats per minute.An image of the chip with week-old heart cell...
During exercise or intense emotion the human heart rate can increase to 200 beats per minute. Thus, in a life span of seventy-five years, with everyday stresses and emotions, a human heart may beat more than 3 billion times. The heart pumps approximately 100 milliliters per beat. In ...

heart and then pumped into the blood stream. It is the atria that draw the blood from the lungs and body, and the ventricles that pump it to the lungs and body. The output of each ventricle per beat is about 70 ml, or about 2 tablespoons. In a trained athlete this amount is about...
Example: 70 beats per minute X 0.07 L/beat = 5.0 L/minute. As heart rate increases so will CO until a certain point. If heart rate is so high so that there is not enough time for the ventricles to fully fill then less blood will be pumped with each heart rate. Related to this, ...
