When suddenly the head begins to feel dizzy, there is shortness of breath, increased sweating, throws into the heat, it seems that the heart is about to jump out of the chest, there are significant changes in the work of many organs and systems. In addition to cardiovascular, kidneys, eyes, nervous system, gastrointestinal tract suffer.
All these symptoms and disorders cause such a seemingly usual increase in the work of the heart, which occurs in a state of rest called tachycardia.
Normal heart function
Normally, an adult in the daytime heart rate (CBC) is 60-80 beats per minute. During sleep, this figure drops to 30-40. After a light jog or physical work, the pulse can jump up to 160 beats per minute.
It is generally accepted that tachycardia is a disease. Although in fact this is far from the case. So doctors in one word called a symptom, which manifests itself in a state of rest and is characterized by a sharp increase in heart rate. The frequency of cardiac contractions (pulse) with tachycardia will be greater than 90 beats per minute.
Tachycardia can appear in healthy people in different situations:
- After strong physical exertion (up to 180 beats per minute);
- During emotional overexcitation;
- Because of the stress experienced;
- During the heat or from the stuffiness;
- After taking certain doses of coffee, tea, alcohol;
- After a sharp tilt or rise.
In other cases, tachycardia causes various disorders within the body. The main causes of tachycardia in women - violations in the endocrine, nervous, autonomic systems, with arrhythmias of various forms and violations of blood flow through the vessels (hemodynamics).
This form appears due to irregularities in the work of the main source of the heart rhythm - the sinus node. The causes of tachycardia in young women are very often caused by violations of the sinus rhythm. The peculiarity of this symptom is an even rhythm (unchanged), but a greatly increased frequency of cardiac contractions - the pulse. The attack can be very long, and it can not be stopped without medication.
Causes of sinus tachycardia in women:
- Adverse reaction to taking medications.
- Diseases of the cardiovascular system.
- Diseases of the heart.
- Poisoning by toxic substances.
- Abuse of caffeine (frequent use of power engineers, custard coffee).
- Severe neurological disorders.
A distinctive feature of this type of tachycardia is a sudden onset, a disordered and greatly accelerated heart beat (much more than with sinus disorders) - 150-300-490 beats per minute. Three types of paroxysmal tachycardia share the place of the disorder:
Atrial tachycardia often occurs after severe fright. Pulse jumps up to 150-190 beats per minute.
With nodal tachycardia, nerve impulses arise at the border of the ventricles and atria and cause arrhythmia. This species is characterized by a sharp start and the same sudden completion of the attack.
Paroxysmal tachycardia in the region of the ventricles is called ventricular fibrillation. This is a life-threatening form of violation, which requires an immediate call of an ambulance. Causes of tachycardia in women causing fibrillation:
- Myocardial infarction;
- Damage to the nervous system;
- Shock states;
- Severe poisoning with poisons;
- Aneurysm of the heart (after a heart attack);
- Ischemic disease;
- Malformations of the heart.
- Dilated pupils;
- noise in ears;
- Compression and pain in the chest;
- Drop in blood pressure;
- Relaxation of body sphincters;
- loss of consciousness.
Tachycardia in women and age
Tachycardia in women is more common than in males. Doctors explain this by the biological characteristics of the organism, associated with a predisposition to a high frequency of generation of an electric pulse. It is considered that violations in the work of the heart can appear only closer to retirement age, but this is not so. Tachycardia can deliver a lot of anxiety at any age and have a variety of reasons.
The most common factors that cause tachycardia in women:
- Hormonal changes (11-20 years):
- Pregnancy (18-40 years);
- Menopause / menopause (after 50-55 years).
All these problems are associated with fluctuations in the level of estrogen in the female body. Other reasons for tachycardia include:
- Adrenal tumors and other disorders of the body's regulation systems;
- Tumors of the hypothalamus and pituitary gland;
- Hypoxia - poor saturation of tissues and body organs with oxygen (including when in a stuffy environment or in a mountainous area);
- Pathology of the lungs (asthma, obstructive bronchitis and others);
- Allergic rhinitis, sinusitis, tonsillitis;
- Hypotension - constantly low blood pressure;
- Excessive use of alcohol;
- Acute viral infections, which are accompanied by a strong increase in temperature;
- Adrenal and thyroid gland diseases;
- Hyperventilation of the lungs;
- Anemia - lack of iron in the body;
- Bad habits (smoking, drug use, energy);
- Severe stress and depression;
- Nervous disorders;
Tachycardia in Pregnancy
The causes of tachycardia in women 30 or even 20 years are also diverse. But most often such violations at a young age causes pregnancy. This is due to a number of reasons related to changes in the body:
- Weight gain;
- Lack of vitamins and minerals;
- Anemia of the pregnant woman;
- Displacement of internal organs caused by uterine growth;
- Toxicosis with frequent vomiting;
- Decrease in blood pressure - hypotension;
Usually, after the delivery, the attacks end, and the heart's work is gradually restored. However, in order to avoid risks for the fetus and the mother with tachycardia, a number of examinations are prescribed for the pregnant woman:
- Holter study - daily monitoring of the heart.
Based on the results of the examination, prescribe potassium and magnesium preparations for pregnant women, sedatives of plant origin, recommend limiting exercise and emotional rest.
Even girls at puberty have mild attacks of arrhythmia. They are considered quite acceptable for a healthy organism, if they do not bother much and quickly pass without any medical intervention.
The causes of tachycardia in women of 30 years can be associated with hormonal imbalance, namely, fluctuations in the level of triiodothyronine, thyroxine and calcitonin. Address to the doctor-endocrinologist if besides a tachycardia you are disturbed:
- Mood swings;
- Problems with sleep;
- Severe sweating;
- Trembling of hands;
- Malfunctions of the menstruation cycle;
- Sharp weight loss (while maintaining normal diet and exercise).
The causes of tachycardia in women under 40 years of age when these symptoms appear are often very simple. The most common problem is the functioning of the thyroid gland - hyperfunction. Such a violation with timely and proper treatment is easily amenable to correction and in the future it does not cause any special concerns.
The causes of tachycardia in women after 50 years are very often associated with the onset of menopause. During the menopause, the production of estrogen is dramatically reduced. Namely, this hormone regulates the work of the vegetative system, which affects the activity of the heart and promotes the expansion of blood vessels. Therefore, immediately consult a treating gynecologist if, in addition to tachycardia, you began to notice:
- Night sweats;
- Malfunctions of the menstrual cycle;
- Dryness of mucous membranes and skin;
- Mood swings;
- Frequent urge to urinate;
- Decreased desire.
Some women need hormone replacement therapy, drug-induced relief of severe attacks of tachycardia, as well as therapy to widen the lumen of blood vessels and improve blood flow.
As additional agents that relieve the symptoms of rapid heartbeat, you can apply:
- breathing exercises;
- yoga classes;
- Meditative and other kinds of relaxing practices;
- Infusions of motherwort, valerian, sage and St. John's wort.
Tachycardia and blood pressure
Most often, an attack of tachycardia is accompanied by a decrease in blood pressure. In this case, you will feel:
- Rapid heartbeat;
- Lump in the abdomen;
- Pain in the occipital region of the head;
- A sense of panic and fear;
- Pain in the sternum.
Such symptoms can cause a strong loss of blood, shock conditions (toxic, infectious, anaphylactic, traumatic shock), vegetovascular dystonia and usual pregnancy.
To stop the attack, you can try to strain the muscles of the limbs and the press for 15-25 seconds or to hold the breath for a while after a long inspiration.
Even if this recommendation has helped, the doctor should be contacted as soon as possible. The causes of tachycardia in women under 40 and older can be the most serious. And the conclusion can be made only by the doctor after passage by the patient of full inspection.
The causes of tachycardia in women under normal pressure are most often associated with:
- Problems in the thyroid gland;
- Severe stress or fright;
- Various diseases of the psyche;
- Lack of sleep;
- Excessive use of alcohol.
It should be noted that tachycardia with increased blood pressure occurs rarely.
Treatment of tachycardia
There are three directions in the treatment of this symptom:
- Removing (stopping) of symptoms by intravenous injection of "Novokainamid" or "Kordaron."
- Normalization and maintenance of a normal pulse. The use of beta-blockers or the drug "Digoxin."
- Preventing the formation of thrombi - drugs that dilute the blood (for example, "Warfarin").
- Treatment of a disease that causes tachycardia.
