Normal heart rate in humans - this swing of the vascular walls, that happens to meet a certain rhythm and the corresponding frequency of contractile activity of the myocardium, so normal indicator frequency of these oscillations is a reflection proper operationall structures of the circulatory system in general.
Evaluating the performance rate, can be reliably judged not so much by the intensity of how much of the regularity of myocardial contraction, as well as on the state of the vascular walls of the arteries.In a situation where the pulse waves are generated through various time intervals, which occurs when the pulse erratically, the physician should make every effort to find the root cause of the condition.
Normal pulse parameters are shown not only its rhythm, but a certain frequency, representing a limited number of vibrations per unit of time, namely, in a minute.The average normal heart rate is a mark of a person is limited from 60 to 90 beats per minute.This pulse r
normal pulse in an adult
Depending on the level at which the vascular bed, measure the vibrations of the vessel wall, emit different types of heart rate (arterial, capillary, venous).Investigation of various characteristics of the pulse allows to evaluate the cardiovascular system as well as the presence of hemodynamic disturbances.The main research method is the compression characteristics of pulse palpation of the arteries in the most accessible locations.It is preferred to carry out the pulse palpation simultaneously in both upper limbs, and with the asymmetry of the pulse required to reflect this fact in the minutes.The asymmetry of the pulse can be observed in various vascular anomalies, blockage of the lumen and compression effects on the vascular wall from the outside.
Despite the fact that the most affordable place to pulse palpation is the projection of the position of the radial artery, reliably carry out this manipulation can be all over the superficial vessels (temporal, thigh, neck region, dorsum of the foot).Compression pulse palpation is a subjective method that does not have 100% confidence.To determine the objective characteristics of the pulse should perform a graphical its registration or sphygmography.In the study of heart rate of a healthy person is marked by steep sphygmography raising pulse wave it up and slow decay, and the presence of abnormal activity of the cardiovascular system, a change in shape of the pulse wave.
main characteristics of the pulse that necessarily reflected in the minutes sphygmography are: frequency, rhythm, power, speed and content.The normal heart rate is a measure of the level of 60-80 beats per minute, so changing this parameter in either direction indicates the presence of rare or frequent pulse.There are physiological conditions in which there may be a slight change in the normal heart rate, for example, hyperthermal syndrome, in which the increase in skin temperature for each degree is accompanied by increased heart rate by 10 beats.
In addition to determining the pulse rate in a healthy or sick person is the definition of mandatory deficit rate, ie the number of pulse beats less in comparison with the rate of contraction of the heart.The appearance of the patient's heart rate indicates a significant deficit of circulatory failure, and may be the only sign of human life-threatening condition.
Normal heart rate at the person assumes that the rhythm of the appearance of the pulse waves, which are registered with the same frequency per unit of time.In a situation where the appearance of the pulse wave is chaotic, we are talking about pulse arrhythmia.
In the process of filling the pulse affects the amount of blood that is ejected during systole in the arterial tree, as well as flexibility and extensibility of the vascular walls of the arteries.Under normal circumstances, a person says a full pulse.In a situation when the arterial tree receives a smaller volume of blood, there is the appearance of a small pulse.There are a number of severe emergency conditions, in which there is a minimum content of the blood vessel, the doctor can record only thready pulse.In the process of filling a normal heart rate can be adversely affected by the poor state of the vascular wall, which is observed in atherosclerotic lesions.Severe myocardial damage observed in ischemic damage it is accompanied by the appearance of signs of alternation of the pulse wave of filling large and small, that is, there is the so-called "intermittent pulse."
Capillary pulse is determined by the rhythmic extension of the minimum caliber arterioles, arising as a result of a sharp and substantial increase in the pressure gradient in the arterial bloodstream during systolic contraction.At this time there is a large spread of the pulse wave of arterioles to the smallest caliber and at the same time, maintaining a continuous flow of blood in the capillary bed.Capillary pulse has a maximum value at the aortic valve.There are pathological states in which the marked involvement and capillaries in the pulsator fluctuations, such as hyperthyroidism, fever hectic type.Determination of capillary pulse of light is carried out by crushing her lips with the help of the slide and the detection of variable corresponding to the pulse, pallor and redness of the mucous membrane.
venous pulse variations presented venous vascular wall as a result of reductions in systolic and diastolic relaxation of the right heart, which provoke the alternate acceleration and deceleration of the outflow of venous blood in the cavity of the right atrium and the corresponding voltage and spadenie vascular wall veins.Indicators
normal pulse in one and the same person may vary considerably depending upon the environment and condition of the patient.Particularly pronounced changes in heart rate figures during physical activity, and therefore, cardiologists recommend to everyone who wants to engage in sports or other kind of physical activity to determine in advance the normal heart rate before exercise and at peak exercise.
So, at quiet long walking normal pulse rate up to 100 beats per minute, while a short jog provokes more pronounced changes in heart rate indicator, even in a healthy person.
Determination of heart rate during physical activity of varying intensity to avoid the risk of cardiovascular complications.Thus, an increase in heart rate up to 130 beats per minute for a healthy person is not an indication to stop the exercise, while the rate of 170 beats per minute is a border and cardiologists do not recommend exposing a body of physical activity.
In addition to determining the pulse rate during physical activity should record the time during which the heart rate is normalized after the cessation of physical activity.Under normal conditions, the pulse must be normalized by no more than five minutes.
normal heart rate values can vary considerably according to the age category, and human health.Thus, the normal pulse man of 50 years exceeds the standards of the pulse of the younger man on the 5-10 attacks, due to the physiological restructuring of the cardiovascular system.In addition, the normal pulse rate for men has a relatively lower values than those of the female.
normal heartbeat in a child
During the routine physical examination of the child during a visit to a pediatric office prerequisite is to measure heart rate, as the main indicator of normal activity patterns throughout the cardiovascular system.Identify even the slightest deviation from the normal heart rate of the child is the basis for further investigation in its entirety.Minimum pulse deviation from the standard values, tend to be a physiological compensatory in nature and do not require medical correction.More pronounced changes should be regarded as an urgent pathological condition, in need of immediate emergency correction.
in the factors affecting the pulse rate of a child may act indicators of the state of the environment in which it is momentarily or permanently, as well as the presence or absence of an underlying disease.It is not modifiable factors, having reflected on the state of the pulse, is the child's age.There is a correlation, "the older the child, the smaller the pulse rate is normal."
normal pulse a teenager is an average of 75 beats per minute, however, may vary slightly in the range of 60 - 80 beats per minute.For measuring the pressure of the vascular walls of the arterial bed is equally often used two techniques: palpation and registration tool with the help of special devices.
children age newborn pulse period measurement is made in the projection of the location of the carotid artery, which is palpable in all conditions.When viewed in older children the most affordable place to palpation is the palmar surface of the wrist joint in the projection location of the radial artery.
Technique pulse palpation of the child is no different from that of adult patients.Priority should be placed middle and index fingers on the palmar surface of the wrist at the location of the radial artery and carefully carry out counting heartbeats for 30 seconds and multiply the data obtained by two.In a situation where a child has signs of cardiac rhythm should be to count heart rate for one minute.
validity of the data in the calculation may significantly reduce the non-compliance with the implementation of manipulation techniques, as well as violations of the environment.So, during the day the child's performance may differ significantly pulse and this depends on the extent of his physical and psycho-emotional activity.The minimum is a normal pulse rate at rest is observed during deep sleep, so most beneficial and informative definition is the heart rate immediately after waking up.When counting the pulse child should be in a horizontal position, as even minimal physical activity can adversely affect the reliability of the results.
should not draw conclusions and normal pulse rate, based only on the single measurement pulse.It is necessary to count the pulse for a few days in one and the same time, and only then determine the mean value of the normal frequency for a given child.Determining heart rate at the time of physical activity also has clinical significance, because measuring this indicator can be seen on compensatory possibilities in each case.Normal pulse rate at the time of the child's physical activity is calculated by the formula: 220 minus your age heart rate of the patient in years.In the case where the counted number exceeds the normal contractions of the heart pulse parameters defined by the formula even at 10-20 beats, immediately limit physical activity.
normal pressure and pulse per minute
Due to the fact that the performance of the pressure gradient blood vessel lumen are most important in maintaining a normal heart rate, the definition of these two values is mandatory for the examination of the patient.Changes in blood pressure to a greater extent adversely affect the characteristics of such pulses, the voltage and speed.
example, voltage or solid pulse is observed in the patient at the time of high blood pressure, since under these conditions requires more than the norm, efforts to compress the artery and stop the pulsation of its walls.Low blood pressure values are accompanied by the appearance of a soft pulse, as compression of the vascular wall may require minimal effort.
The rate also affects the pulse oscillation of the pressure gradient in the vascular arterial bed during systolic contraction and diastolic relaxation.In a situation where during systolic contraction observed a rapid increase in the pressure gradient in the lumen of the aorta, and in the period of diastolic relaxation has been a rapid drop in pressure, there is a quick dilatation and spadenie vascular wall, so the pulse becomes imminent.This condition is most common for people suffering from aortic valve insufficiency.
In the case of slowly increasing gradient of blood pressure in the lumen of the aorta during the systolic contraction and slow its decline during the diastolic relaxation noted the appearance of small slow heart rate, which is typical for people suffering from a narrowing of the aorta.
Thus, to determine changes in the normal values pressure and heart rate, which are in correlation may require the use of additional instrumental examination methods - namely, Holter monitoring blood pressure and pulse during the day.Under normal conditions, parameters as blood pressure and heart rate may change slightly, but must conform to the age regulations.
Table normal heart rate in humans
in their practice in any specialty physicians rely on existing standards and algorithms.Cardiologists in its practice also use the regulatory framework regarding the definition of pulse rate as one of the main criteria for the normal functioning of the cardiovascular system.
of the table below are listed in the normative values of heart rate depending on the age group of the patient.Looking at this table, it becomes clear that the normal value of the maximum heart rate is observed in the baby after birth and in the first month of life, referred to the neonatal period.With increasing age of the individual correlation decreases normal pulse rate, and this dependence is observed up to the age of fifty man.According to the table, the normal pulse rate in more than 60 years of heart rate in 50 years, so it is safe to observe an increase in heart rate in humans after 50 years.Scientific research in the field of cardiology have shown the sharp acceleration of the pulse with the achievement index of 160 beats immediately before the death.
Considering this table of the normal rate and taking into account its data in the assessment of heart rate in humans, it should be remembered that the figures in this table are applicable only for healthy individuals.Women with early onset of menopause are prone to the emergence of a functional tachycardia due to hormonal disruptions in the body, and not in violation of the heart, so a normal heart rate in 40 years, this category of persons may exceed the average standards.
of the table below normal heart rate is based on standard values only according to age categories, although cardiologists say different values of the normal heart rate, depending on gender.Thus, the normal pulse in younger women may differ significantly from normal values heartbeat men in the same age category.
