The heartbeat is the mechanism that causes the contraction of the ventricles, and reflects the number of times your heart beats in a minute, depends on heart rate natural on the individual in terms of age and size of his body and fitness condition of the heart and blood vessels, whether they are standing up or sitting, and took the drug or not until the temperature of the air affect the heartbeat.
It can be emotions effect on heart rate, since heart rate rises when it is exposure to danger or when faced with some pressure, the heart rate is the number of heart beats or pulses per unit time which is usually accurate. Can be defined also by the number of states in the second.
The location of the heart and how it works
The heart is a muscular organ located in the chest behind the sternum, to the left in most individuals. Its size is about 1.5 times the size of a person’s fist, and divides the thick wall of the heart into two parts, the left and right. Each part of the cavity, namely the atria and ventricles connected by a valve. The heart works as a pump operates the constriction of their regular push blood throughout the body and therefore provide oxygen to the whole body.
Every day the heart pumps about 8,000 liters of blood. Where there is to four valves, located between the atria and ventricles of the hand, and at the outlet of the ventricles on the other hand, gives when you shut down the flow of blood back in the wrong direction. Thus the closing sound of the valves gives the pictures a fashionable pulse.
The main methods for measuring heart rate
The survey of highways to measure the pace of the heart, the separation of the two major problems that arise in the way the devices work to measure the heartbeat. Can also detect the activity of the heart which manifests itself by palpation and direct, and by endoscopy of the blood and vesicles and to study the pulse of the heart. But the two main ways are The Heart Photography to. You can determine the average balance of the heart by counting direct, or through the use of a pulse counter.
The natural values of the address pulse of the natural heart
Choose values for natural heartbeat by:
- Newborn: 140 ± 50 beats per minute.
- 1-2 years: 110 ± 40 strokes per minute.
- 3-5 years: 105 ± 35 beats per minute.
- 6-12 years: 95 ± 30 beats per minute.
- Adolescent or adult: 70 ± 10 beats per minute.
- Elderly person: 65 ± 5 beats per minute.
When healthy adults in the salary rate ranges heart rate between 50 and 80 beats per minute.
During exercise the maximum heart rate theory is 220 minus age (for example: 220 – 40 years = 180. But heart rate is not constant over 24 hours because of the state of various biological. Is maximum around noon.
In addition to digestion, heat and cold cause an increase in heart rate.
Affect pressure also heart rate through three mechanisms: neural mechanisms and chemical and physical properties. We have a nervous system independent and is characterized by the presence of nervous system sympathetic and non-sympathetic. The first system has the function to increase heart rate. The second reduces it.
Secondly: the arteries
Is evaluating the rate and regularity of the heartbeat on the pulse of the central. Can easily access to the pulse of the carotid artery, but its proximity to sensitive areas makes taking the femoral pulse is difficult, and therefore will conduct this evaluation as a priority in the carotid pulse, unless the arrival of its hard for example (neck, fat, and cervical collar).
Radial pulse: if you did not notice the presence of radial pulse in any of the two sides, it may indicate low blood pressure, and if it is realized on only one side, it refers to the compression of an artery or bleeding on the side where they are not perceivable, especially in the case of a trauma (fracture, dislocation) of the upper extremity, or compression (such as being locked in a vehicle, compressed by a heavy object, breakdown, etc). These elements must be supported by external others, such as the presence of pallor in mucous membranes and the cold.
Road gas scenario to calculate a pulse wave or pulse rate heart
Listening to the heart through a stethoscope, reliable too, but it does not allow monitoring of the level over time.
The downturn of the international to the heart muscle is secondary to polarize the membranes of cells that are detected by electrodes located on the skin. Where is the registry in real time on the form of a trace on the scope, which is a simple way to control mechanism of heart rate.
The method of measuring the proportion of hypoxic
Non-surgical method (non-painful) by placing the sensor at the end of the finger or on the ear, with the analysis of the contrast in the color of the blood in accordance with the oxygen. This variation periodically, and is synchronized with the heart rate.
Dynamic way blood
In some cases, can be the introduction of a thin catheter in the artery, is connected to the sensor Pressure. A variation of the international pressure measured makes it possible to calculate the heart rate in real time.
How to measure the heart rate normal?
There are many areas of the body that can measure the heartbeat. Including: wrist, on the side of the neck, groin and top of the foot. In order to obtain an accurate reading, place your finger on one of these areas of the body and the number of tunes for 60 seconds. You can also do this for 15 seconds and multiply the number resulting in 4, or for 10 seconds and squeeze in 6, but it is recommended that this number of Pulse for 60 seconds when possible. It’s also better to sit quietly for 10 minutes before taking your pulse. during rest.
The maximum rate of the heartbeat although there is no medical advice definitive about the formation of the pulses is high in the heart, but most experts agree medical that the rate of the heartbeat which is always at the top of the range could be a lot of pressure on the heart and other organs.
Accounts the maximum rate of the pulse of the natural heart
It accounts the most common:
The first account
Is – 220 the year, so for someone who reaches the age of 50 years, we have: 220-50 = 170 beats per minute.
The second account
It is a little more precise than the first, but the first account easier and more practical to learn. When you maintain a normal rate of the heartbeat can get the maximum benefits and reduce the risk of heart disease and that is through the practice of sports in its various forms.
According to the Centers for Disease Control and Prevention, in the case of moderate-intensity physical activity, should be target heart rate for 50% to 70% of maximum heart rate. For example, using the above calculations, the 50-year-old level of 50% and 70% as follows:
- Level at 50%: 170 x 0.50 = 85 beats per minute.
- The level of 70%: 170 x 0.70 = 119 beats per minute for the hard work.
- Must be ranges from your target heart rate for between 70% and 80% of maximum heart rate. The level of 85%: 170 x 0.85 = 144 beats per minute.
No exercise is recommended more than 85% of the maximum rate of the heartbeat because it increases the risk of exposure to heart problems and blood vessels and bones.

Irregular heartbeat and other disorders
Can work disorders that affect the heart rate. An irregular heartbeat makes the heart beat in an abnormal manner, whether too quickly or too slowly or at the rate of irregular.
It is a disorder where the heart rate close to 150 beats per minute or more, and electrical system that controls the heart beats, out of control. This usually requires medical attention.
Is the condition of your heart beats very slowly, often less than 60 beats per minute. This can be as a result of participation in the sinoatrial node, which acts as the pacemaker, or damage to the heart caused by heart attack or cardiovascular disease and treatment here to be either some medication or by installing a pacemaker.
High heart rate and the difference between it and high blood pressure
Some people confuse high blood pressure with high heart rate. Blood pressure is the measure of the force of blood on the walls of the arteries, while the heart rate is the number of times your heart beats in a minute. No there is no direct link between the two, and high blood pressure does not necessarily lead to high heart rate, and vice versa. Like wearing a heart rate during the activity exhausting, but intensive physical training only increases the blood pressure in a simple.
