Heart and pulse
The heart is the main organ in the body in conjunction with the brain, which is the pulse that provides the body with the blood necessary to supply all the organs and organs of the body food necessary to perform all the operations required of him non-stop, and the size of the heart often increases with the period of human growth until the age of puberty almost, It is known that all creatures have one heart or more according to their size, nature and movement. The heart is a pump to pump blood throughout the body to supply all areas of the body and its organs with blood.
The heartbeat is defined as the number of heart beats in a specific time unit, usually measured by a minute. The heartbeat measurement depends on the number of ventricular contractions (the lower chambers of the heart), not on the number of atrial contractions (the upper two chambers of the heart). The pulse is the swelling of the artery due to the blood flows through the blood vessels every time the heart beats.
Heart rate
The normal pulse rate usually ranges from 60 to 100 beats per minute in normal adult humans, although this ratio varies from person to person according to one or more of the factors listed below. It is important to know that the thyroid gland and its neighbors influence and even directly control the work and muscle activity The heart, where doctors call this gland the title of the body battery; because of its important role in the work of the heart, and secrete this hormone called thyroxine, which controls the heart muscle activity, and thyroid gland secretes some hormones to help the heart, but must pay attention to That Iver If this gland increases or decreases it will cause health problems affecting the heart in the first place, and there may be other reasons that lead to an increase or decrease the number of heart beats.
Lack of activity of the thyroid gland leads to a deficiency of secretion of thyroxine, and thus to general inactivity in the body, and lack of activity and vitality, as well as pain in the chest area and a significant slowdown in the number of heartbeat, which may fall below the twenty pulse per minute, Light and non-exhausting sport for a long time to restore the gland activity, in addition to the treatment of thyroid hormone doses may vary from person to person to regulate the work of this gland, and this is the least damage to the gland and control of the simple and within the possibilities available easily, If the increased secretion of this gland, the heart rate increases dramatically and significantly, in turn, lead to fatigue in the body, and needs to treat a compound to control the work of the gland, and work on the apolepsis process to return to normal levels.
It should be noted that the muscular athletic body beats less than the normal body; the pulse rate is about 55 beats per minute for the expansion of the muscle area, and therefore the need for more time to deliver blood to all regions of the body, the heart of the child is beating more than the heart The child’s pulse rate in the first two years is about 90 beats per minute.
Factors affecting the heartbeat
The number of heart beats varies according to the organism, as well as by its size, activity, living space and presence, as well as the human heart rate varies according to several factors including:
- Age: The child’s pulse is not like a big adult’s pulse.
- Movement and sport: As well as athlete and the average person vary the number of blows their hearts.
- Size: A huge person differs from a small person.
- Health and disease: The presence of some diseases increases or decreases the number of heart beat.
- Hypertension.
- Sleep and relax.
- Emotions.
- temperature.
- some medicine.
How to measure pulse
It is important to know that the number of heart rhythms measured in the normal state, sitting on a chair regularly without relaxation, or do any muscle or physical effort, as the measurement must be several times during periods of spacing, and the same position of sitting static, In more than one position manually, namely: the wrist, the neck, the soles of the elbow, and the foot, in addition to the medical devices mounted on the finger.
If there is a rise or decrease in the number of heart beats, you should see your doctor immediately, and there is no doubt that the number of heartbeat decreases in the cases of total sleep, sleep, disease, and general fatigue, and increases in the exercise of any activity such as running, dancing, There are also other factors that may increase the number of heart beats, including: fear, tension and waiting for something important, and all these cases do not represent a health problem or a danger to the human; because it is considered a transient situation that passes over a period of time and then ends.
