Question

What is the normal pulse rate for a woman in each of the 1 st, 2 nd, and 3 rd trimesters of pregnancy?

Answer 1

A pulse rate can be described as the number of heartbeats per minute. The heart pushes the blood through the arteries which expand and contract during the flow of the blood.

Complete answer:
During pregnancy, the blood pumped by the heart gets increased to $30-50\%$ from the normal. The cardiac output increases to 80 or 90 beats per minute. The transistors of pregnancy are marked by specific fetal development in each trimester. The first trimester is the most important and crucial trimester for a baby's development as the body structure and organ systems get developed during the trimester. This causes nausea, breast tenderness, fatigue and frequent urination in the mother's body and a woman experiences different symptoms which can be an increased level of emotions. This trimester includes 0 to 13 weeks.
The second trimester is known as 'the golden period' due to the unpleasant effects of pregnancy that disappears. It includes 14 to 26 weeks of the pregnancy under which the women experience decreased nausea and better sleep patterns due to increased energy levels in the body. The third trimester includes the 27th to 40th week of pregnancy which involves physical symptoms such as shortness of breath, sleeping problems and haemorrhoids. The infant which gets delivered before the 37th week of pregnancy is considered premature or and has certain problems with its growth and development. The infant will face problems in breathing and digesting.

Note:
Some people considered the faster heart rate to be a girl and the lower heart rate to be a boy which will be between 120 to 160 beats per minute. During the 20th to 24th week, the heart rate gets increased to its higher peak which resolves after the 6 weeks of childbirth.
