The heart pumps almost half of the blood volume with each beat. This is referred to as the ejection fraction or EF, which is the percentage of blood pumped out of the left ventricle with every heartbeat.

Is it better to have a lower or a faster heart rate?

The thicker your arteries, the more blood pressure it takes to pump it through. If your arteries are clogged with blood vessels, it does not let as much blood flow by as originaly possible, so the body needs to push the blood through it harder, making your heart beat faster, therefore increasing your heart rate. If your heart rate is high, it means that your heart is not working as hard to pump blood through your arteries. So it is healthier to have a higger heart rate than a lower one.
