Question

A regular check on the unborn baby of a lady towards the end of pregnancy showed a heart rate of 80 beats per minute. What would the doctor infer about the baby’s heart condition from this?
A. Normal heart rate
B. Faster heart rate
C. Slower heart rate
D. Defective brain function.

Answer 1

Hint: The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system.
The pumped blood carries oxygen and nutrients to the body while carrying metabolic waste such as carbon dioxide to the lungs.
In humans the heart is located between the lungs.

Complete answer:
The heart is a muscular organ located just behind and slightly left to the breastbone.
The heart pumps blood through the network of arteries and veins called the cardiovascular system.
The heart has four chambers:
1. The right atrium
2. The right ventricle
3. The left atrium.
4. The left ventricle
Heart beat: Heartbeat is defined as the pulse of your heart.
When the heart pulses and pumps blood throughout your body, this is an example of a heartbeat.
So, according to the given question, the heartbeat of the unborn and the newborn is higher than 80-130 beats per minute.
The heartbeat of the unborn child of the pregnant lady was found to be 80 beats per minute and so the doctors infer that the heartbeat is slower than the normal beats in the unborn.

So, the correct option is option C. Slower heart rate.

Note:
In healthy adults, there are two normal heart sounds often known as a lub and a dub.
It occurs in sequence with each heartbeat.
These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the AV valves (the mitral valve and the tricuspid valve) and semilunar valves (the pulmonary valve and the aortic valve), respectively.
