The smooth muscle relaxes and the arteries dilate to handle the increase in circulating blood volume while maintaining normal blood pressure.

However, the heart rate increases to 82-86 bpm.

Third trimester

By the end of the third trimester, the heart is pumping from 40 % to 90 % more blood than before pregnancy.

The resting heart rate increases to 86-90 bpm.
