It means that you don't really respond to outside stimulus with very much emotion or with the same behaviorisms that most other people would in the same situation. Let me try to give you an example. Say someone tells you that the sky is blue. Normal affect would be baseline, meaning your usual facial expression.
The fetusâ heart begins to beat at 5 weeks gestation, at around 80-85 beats per minute. This rate increases about 3 beats per minute per day during the first month. When the fetus heart is first developed it resembles that of a tube. As the fetus begins to grow, so does the heart. Due to lack of room, that tube begins to bend and twist, beginning to take on the shape of a normal human heart.
Generally from 6 Â½ -7 weeks is the time when a heartbeat can be detected and viability can be assessed. A normal heartbeat at 6-7 weeks would be 90-110 beats per minute. The presence of an embryonic heartbeat is an assuring sign of the health of the pregnancy. Once a heartbeat is detected, the chance of the pregnancy continuing ranges from 70-90% dependent on what type of ultrasound is used.
