From this article you will learn: is the norm a pulse of 90 beats per minute, the normal and pathological causes of such an indicator. When you need treatment, and when you do not.

The average value of the adult pulse is 60-80 beats per minute. An increase in values up to 90 beats may be a sign of the disease or a variant of the norm. For children, depending on the age, 90 can even be a slow pulse.
The concept of the norm in medicine is very relative. If a person's usual pulse is always equal to 50-55, then 80 strokes will be for him already exceeding, and at a standard value of 80-85 strokes - the rate at 90 will be the norm option. That is, not only the absolute figure matters, but also its correlation with the average pulse of a person.
The cardiologist is concerned with the issues of pulse, its changes, elimination of problems with it.
Normal pulse values
Pulse is not a constant value, it varies depending on age, emotional state, time of day, food intake.
The allowed average values are shown in the table:
| Age | Median ( bpm) | Normal deviation ( bpm) |
|---|---|---|
| First 28 days of life | 140 | 110-170 |
| Up to 1 year | 132 | 102-161 |
| 1-2 years | 123 | 95-154 |
| 2-4 years | 115 | 90-140 |
| 4-6 years | 106 | 86-125 |
| 6-9 years | 94 | 78-114 |
| 10-12 years | 80 | 60-100 |
| 13-15 years | 75 | 55-95 |
| 16-50 years | 70 | 60-80 |
| 51-60 | 75 | 64-85 |
| 61-80 | 78 | 70-89 |
Up to the age of 15, the pulse rate of 90 beats per minute is normal. This frequency is explained by the small size of the child's heart and the increased oxygen demand and energy reserves of the growing body.
In mature and old age there is also some acceleration of pulsation - about 10 beats for every 10-20 years. With aging, the body requires more blood supply and faster pumping of blood.
Causes of normal( physiological) pulse increase up to 90 strokes
In the absence of complaints, all of the following conditions do not require medical intervention and treatment.
- More frequent pulse fluctuations are typical for women, about 7-9 strokes higher than for men. Women are usually less tall and heavier( that is, they have less heart), and less often are engaged in manual labor( their heart is less trained).
- Smaller people also have a faster pulse. For them, 90 beats per minute is acceptable in the second half of the day, when physiologically all people are experiencing an acceleration of the heart. And at night, the pulse is usually slightly less than the daily values.
- Reduced blood pressure is accompanied by an increase in the heart rate to compensate for oxygen starvation.
- Temporal acceleration of pulsations occurs during training, physical activity, running. Actively working muscles need food - glucose, which is transmitted with blood flow, and oxygen. It is possible to increase to 180-200 beats. But in the norm in 3-5 minutes the heart rhythm should return to the initial values.
- When worried, worried, frightened, a stress hormone is released - norepinephrine, which accelerates the work of the heart. The body is mobilized to respond to an atypical situation. With a healthy functioning of the cardiovascular system, this heart rhythm calms down after 5-10 minutes.
- The same situation is observed during and immediately after sexual intercourse in both partners - this is a physical and emotional shake-up of the body.
- Abundant food intake, especially excessive consumption of alcoholic beverages, freshly brewed coffee, strong tea leads to a temporary increase in heart rate to 90 strokes.
- The frequency of pulsation depends on the hormonal fluctuations in the body. So, before the menstrual period and during menstruation in women, the pulse of 90 bpm may be normal, since the hormone of pregnancy - progesterone - acts. With the onset of menopause, when there is a deficiency of estrogen( female sex hormones), women also experience an increase in heart rate.
- Physiological tachycardia accompanies a woman's pregnancy. The kid requires increased consumption of oxygen and nutrients, so the heart of a pregnant woman beats faster - up to 90-100 beats per minute. In the third trimester, before birth, a pulse of 100-110 beats per minute can be observed, this is a normal value that does not require treatment. After giving birth, the indicators will return to the normal values of the woman.
- Pulse rate is associated with hyperthermia( fever).The normal reaction of the body is an increase in pulsation by 10 beats per degree above 37. Accelerated heartbeat contributes to increased heat transfer - the body is protected from overheating.
- There is an opinion that the heart rate depends on the temperament of a person - in choleric and melancholic people, it reaches 90 strokes.
Pathological pulse acceleration up to 90
A frequent pulse can indicate the presence of diseases in the body. Pathological tachycardia develops against the background:
- of congenital or acquired heart defects;
- diseases of the cardiovascular system - cardiosclerosis, myocarditis, cardiomyopathy;
- persistent changes in blood pressure( hypo- and hypertension);
- acute poisoning;
- of chronic bronchopulmonary diseases, accompanied by a persistent cough;
- malignant tumors;
- of organic or functional brain lesions;
- endocrine-metabolic diseases, especially hyperthyroidism( increased thyroid function);
- hypoxia( lack of oxygen);
- hypokalemia( decreased serum potassium concentration);
- shock of any etiology - hemorrhagic, painful, traumatic, cardiogenic.
Regardless of the cause of abnormal, uncharacteristic tachycardia, it is necessary to urgently seek medical help.
Heart rate disorders with increasing frequency - tachyarrhythmias - require emergency hospitalization in a cardiac hospital. With this pathology, the heart contracts frequently and at different intervals of time.
To identify the cause of pathological tachycardias will help a comprehensive examination of cardiologists and doctors of related specialties: endocrinologists, neuropathologists, pulmonologists, gastroenterologists, oncologists.
When treatment is required
At home, it is important to be able to distinguish between conditions when medical intervention is required, and physiological( normal) tachycardia.
The normal increase in pulsation is not accompanied by any deviations and complaints. Occurrence of symptoms unusual for a person should alert the patient and serve as an occasion for visiting a doctor.
The signs of abnormal tachycardia include appearance on the background of acceleration of pulsation:
- dizziness;
- chest pain, behind the sternum;
- shortness of breath;
- vision disorders - double vision, cloudiness, flashing of "flies", loss of visual fields;
- hyperhidrosis( increased sweating);
- weakness;
- cooling and trembling of limbs;
- of pre-fainting conditions, fainting.
These symptoms can talk about the development of severe disruptions in the functioning of vital body systems and require treatment.
Methods of treatment depend on the cause of increased heart rate.
General recommendations for heart rate reduction
If a rapid heartbeat develops, calm down, inhale deeply and calmly several times.
The inhalation of essential oils of lemon, mint helps calm the heart rhythm.
Herbal teas and infusions with soothing action( motherwort, valerian, St. John's Wort) are also able to normalize the pulse.
