High pulse: what to do?
Pulse displays a functional activity of the heart in the first place – the frequency and rhythm of its contractions. The increase in heart rate is common, which may develop due to various physiological and pathological reasons.
The mechanism of formation of the pulse
During contraction (systole) of the heart from the ventricles into the bloodstream is pushed out a certain volume of blood during relaxation (diastole) the same amount is returned to the Atria, thereby providing blood flow in blood vessels. Arteries have elastic walls, which at the time of diastole of the heart and ejection of blood extend, and during diastole return to the starting position – this is a pulse wave, or pulse. You can feel it by touching the large arteries by means of pressing to the bone.
While it is possible to determine several basic characteristics showing the operation of the heart. These include the frequency, rhythm and contractions, and the degree of filling of the artery. Normal pulse rate varies from 60 – 80 per minute. Increased this figure is under the influence of various physiological and pathological factors, which develops due to tachycardia (increase heartbeats).
When increased heart rate normal?
High pulse may be due to the effects of the various reasons that cause an increase in heart rate, aimed at providing all the tissues of the body sufficient blood, nutrients and oxygen. To such physiological factors include:
Hypertension is no longer a disease?
Doctors are shocked by the statement, the chief cardiac surgeon in the country Leo Beaucaire.
- Increased physical activity – physiological tachycardia develops after exercise, hard work, usually after a short period of time the pulse returns to normal.
- Emotional stress – fear, negative emotions cause increased activity of the nervous system and increase levels of the hormone adrenaline, which lead to physiological tachycardia.
- Taking certain foods (coffee, black tea), which have a stimulating effect on the nervous system and cause the development of reflex tachycardia, the level of pressure may be low. Also some medications can increase the heart rate (before assignment doctor must warn the patient about the influence of the drug).
Knowledge of the causes, causing increased heart rate is normal, will limit their impact is to normalize the physical and emotional stress, reduce coffee consumption.
Pathological causes of high pulse
Depending on the localization of the pathological process leading to the development of tachycardia, distinguish cardiac and noncardiac causes. Cardiac factors include:
- The violation pulse generation in the pacemaker of the heart (nerve node, localized in the right atrium) or the formation of abnormal hearth rhythm. These pathologies cause the heart to contract more often more than 100 beats per minute, usually with a concomitant change in the rhythm (arrhythmia).
- Inadequate nutrition of the heart structures, primarily of the myocardium and the nerve fibers leading to changes in their functional activity.
- Different heart disease, under which he has to perform more work, accompanied by an increase in the number of beats.
- Hypertension – high blood pressure when the heart reflex is reduced more frequently to ensure adequate blood flow in blood vessels.
Extracardiac causes usually lead to the dysregulation of the functional activity of the heart, particularly of the nervous and endocrine systems. It relates to several pathological States:
- Vegetative-vascular dystonia on hypertonic type – dysregulation of the autonomic nervous system, leading to increased pressure and increased heart rate.
- Increased activity of the thyroid gland with increased secretion of its hormones – rapid heart rate is a result of increased metabolism and activity of the nervous system caused by the effect of thyroxine and triiodothyronine.
- The change of the regulating influence of the Central nervous system – neurosis and mental pathology cause significant functional impairment in the activity of internal organs, blood vessels and heart.
- Hormone-producing tumor of the adrenal medulla is the cause of increased secretion of the hormone adrenaline, leading to increased pressure and tachycardia.
Pathological diagnosis of the reasons allows you to determine why increases the heart rate for later appointment of adequate treatment.
How dangerous elevated heart rate?
Elevated heart rate over 100 per minute is a dangerous condition. This may be a high pulse pressure (systolic), impaired rhythm of heart contractions, which significantly increases the risk of intravascular thrombus formation.
What to do with the increased heart rate?
If there is a systematic increase in heart rate, which is usually felt in the form of palpitations, intermittent dizziness, you must consult your doctor who will prescribe the appropriate diagnostic tests. To determine the pathological causes of heart rate is normally conducted electrocardiography, ultrasound examination of the heart, abdominal organs and the thyroid gland, laboratory determination of the level of hormones in the blood.

Actor Oleg Tabakov said
How to lower your heart rate?
The basis for effective therapy of tachycardia is to combat the influence of pathological causes of its development, the direction of which is determined by the physician. Also therapeutic interventions necessarily include pills high heart rate. These include drugs of the group of antiarrhythmic drugs (Cordarone) and beta-blockers (Bisoprolol).
To take these pills in high pulse it is recommended to normalize the heart rate. Vascular dystonia on hypertonic type, it is recommended to drink infusions of medicinal plants with sedative effects (motherwort), which are also not contraindicated in pregnancy.
If the pressure level is large, the therapy included the use of antihypertensive drugs. Pre-hospital emergency care in a situation when the pulse is very elevated (up to 200 per minute), includes moderate pressure on the eyeballs with the fingers, whereby aktiviziruyutsya parasympathetic nervous system decreasing heart rate.
Sometimes after using such therapeutic measures the pulse may be small (less than 60 per minute). To improve it, you should drink a Cup of strong sweet tea, which due to the content of theophylline gently increases the heart rate.
