What should an adult’s pulse be like: normal and pathological

Normal heart rate for an adult: table by age

The normal heart rate of an adult by year (age) is given in the table:

In an adult, the heart rate norms by age and the permissible heart rate limits in a child under 15 years of age differ significantly, which can be seen in the following table:

Knowing what the normal heart rate is for women and men by age, you can avoid many diseases. Measurements should be taken at rest. Under the influence of other factors (sports, pregnancy), slight deviations are possible.

Heart rate while walking

While walking, there is a slight increase in heart rate. How many heartbeats there will be per minute depends on the person’s fitness. For people leading a sedentary lifestyle, the heart rate can jump to 120, but for people who like to walk, it will remain within 90-100. To calculate the maximum permissible limit, subtract the person's age from 180.

When walking, the permissible heart rate is as follows:

• 15 years - 165;
• 35 years old - 145;
• 55 years old - 125;
• 75 years old - 105.

Heart rate at rest

The resting pulse is determined in the morning.
A person needs to sit on a chair and count his pulse. Changing body positions or taking measurements in the evening is not recommended, as the final result will be distorted. Generally accepted norms at rest:

• adults – 60-80;
• elderly – 70-90;
• teenagers - 70-80;
• children under 2 years old - 90-100;
• newborns - 130-140.

Heart rate while running

While jogging, a lot of stress is placed on the heart. People trying to lose weight should keep their heart rate close to the upper limit. If the goal is to strengthen the cardiovascular system, then you need to stop at a figure not exceeding 60-70%. To calculate the norm, you need to subtract your age from 200:

If, against the background of an increase in the pulse (within acceptable limits), the pressure readings remain normal, then the development of pathologies will not follow. Elderly people need to be especially careful. Their body is unable to withstand heavy loads.

Permissible heart rate during pregnancy

A woman who is expecting a baby experiences increased heart rate around the 5th month. This phenomenon is associated with an increase in circulating blood volume during fetal development. Usually the increase is insignificant and gradually the indicators return to the acceptable limit:

• Heart rate norms in children: table of heart rate correspondences from newborn age to adulthood

• at 14-26 weeks there is an increase of 10-15 contractions from the norm;
• the maximum increase occurs between 27 and 32 weeks;
• gradual normalization occurs closer to the birth of the child.

Increased heart rate during sleep

Reducing the impulses of the cardiovascular system during rest is considered natural for a healthy person. Medical experts confirm the dependence of heart rate rhythms on the effectiveness of sleep, its depth and quality.

In most cases, sleeping people see dreams in color or black and white. Beautiful and pleasant dreams periodically change to nightmares, which affect the nervous system. The result may even be a jump in blood pressure. But this is not the only thing that affects the quality of dreams.

Tachycardia in the morning

Heart rate fluctuations during sleep can also cause:

• changes in the functioning of the thyroid gland;
• prolonged stress and depression;
• impaired blood circulation;
• slagging of the body and intoxication;
• internal bleeding;
• lack of water in the body.

Tachycardia harms proper sleep, causing anxiety with possible headaches and pressing pain in the chest.

Measurement

Pulse measurement is usually performed at the wrist. It is enough for a person to count the number of pulse waves in 1 minute. To obtain more accurate data, it is recommended to take measurements on both limbs. As a comprehensive examination in a hospital setting, the doctor will first find out the heart rate, then he will count the number of respiratory movements (RR) in 1 minute and determine the type of breathing. The resulting indicator is especially important for assessing the child’s development.

When measuring your pulse, you need to pay attention to its rhythm. The shocks should be of equal strength and at equal intervals of time. If there are no deviations, it is enough to spend 30 seconds on the procedure, and then multiply the result by 2. If a clear disturbance in the heartbeat is detected, it is better to spend at least 1 minute on the measurement and consult a doctor. The specialist will prescribe instrumental examination methods. The main one among them is electrocardiography (ECG). It will allow you to evaluate the electrical activity of the heart and identify the causative factor of arrhythmia. As a supplement, the following tests are prescribed:

• Daily ECG monitoring will allow you to see changes in heart function throughout the day under the influence of various factors.
• A treadmill test is prescribed to assess heart rate under the influence of physical activity.

Due to problems with blood vessels or injuries, it is sometimes necessary to count pulse waves in other arteries. Instead of the wrist, you can palpate the neck. The vibrations will come from the carotid artery.

conclusions

Often parents are concerned about the baby's rapid heartbeat, mistaking it for a pathology. The pediatrician will explain what the child’s pulse should be depending on age, and will notice deviations in time.

For children with arrhythmias, a program of clinical observation and rehabilitation has been developed to prevent paroxysms and reduce the severity of attacks. It provides for a special daily and study regimen, a favorable psychological microclimate in the family, balanced nutrition, and dosed physical activity.

Features of bradycardia

A slowing of the heart rate to 50 beats or below is called bradycardia. It is a sign of physiological and pathological factors. In the first case, the list of reasons for a decrease in heart rate is as follows:

• During sleep, a person's metabolism slows down, body temperature drops slightly and heart rate decreases by about 10% of normal. The reason for the change in indicators is the complete relaxation of the body.
• Stimulating reflex zones (eyeballs, carotid artery) can inadvertently cause a slight slowing of the pulse.
• In older people, bradycardia can be a consequence of age-related cardiosclerosis. Areas of connective tissue scattered throughout the myocardium impair cardiac contractility, which contributes to a decrease in heart rate
• When exposed to cold for a long time, the heart rate slows down as a protective reaction. The body begins to save resources in order to resist adverse effects longer.
• Constant physical activity forces the heart to work harder than it should. Tissue hypertrophy begins, against the background of which bradycardia develops. For professional athletes, a heart rate in the region of 40-45 beats per minute is considered normal.

The pathological form of bradycardia is a consequence of the following factors:

• inflammatory diseases of the heart muscle;
• myocardial infarction;
• taking antihypertensive medications;
• impulse conduction disturbance;
• hypothyroidism (thyroid hormone deficiency);
• hypotension (low blood pressure);
• stomach ulcer;
• high intracranial pressure.

If it is not possible to identify the causative factor, a diagnosis of “idiopathic bradycardia” is made. If it is not accompanied by other disorders and the symptoms are not particularly pronounced, then it is also equated to physiological forms.

Where is the best place to measure your pulse?

The most convenient place for measuring the pulse is the wrist, on which the radial artery is located. You need to place your index and middle finger on this artery. You cannot apply other fingers, because it is easy to confuse the pulsations of their vessels with contractions of the artery on the wrist.

There are some objective reasons for high heart rate in men, which can distort the correct indicators characteristic of a particular person. So, you cannot measure your pulse:

• for infectious diseases and high body temperature;
• after active sports and other physical activities;
• when taking medications;
• after bath procedures, visiting a sauna and a hot shower;
• during alcohol intoxication;
• after sexual intercourse;
• after prolonged exposure to high or low temperatures;
• on a full stomach.

Pathological causes

The heart rate can vary in one direction or the other due to pathological changes in the body. We are talking about six main diseases.

Hypothyroidism

Hypothyroidism is a deficiency of thyroid hormones and the reverse process is hyperthyroidism with an excess of substances in the bloodstream. Hemodynamic disturbances affect the third reflex zone of the heart.

In the first situation, tachycardia occurs, in the second - a decrease in heart rate per minute. Prolonged course of both conditions is associated with an increased risk of fatal or disabling complications.

Diabetes

Generally destroys organs and systems, right down to the visual analyzer. With endocrine pathology, the heart wears out faster; without proper treatment, natural death occurs 10-15 years ahead of schedule.

Diabetes of the first type is especially dangerous, since it is not treated, but only corrected with medication, and not always to a sufficient extent.

Hypercortisolism or Addison's disease (reverse phenomenon)

Impaired synthesis of cortisol and other corticosteroids (to a lesser extent). Maintenance hormonal therapy and surgery to eliminate the root cause are required (in the vast majority of cases, the main factor is a tumor in the adrenal glands or pituitary gland).

Congestive heart failure

Causes cardiac ischemia and accelerates the rhythm, sometimes to significant levels. The course without therapy entails a heart attack, sooner or later (usually within 3-5 years from the onset of the first symptoms, by which time the disease is far from at the initial stage of development).

The first signs of heart failure are described in this article.

Acute myocardial ischemia

Leads to death in 35-50% of cases. An extensive type of heart attack is fatal in 95% of clinical situations. Arrhythmia is the hallmark of the process, along with accompanying manifestations.
