Rapid heartbeat

Tachycardia is not a separate disease, but a consequence of abnormalities in other body systems. It is a type of arrhythmia in which the pulse rate increases to 90 beats or more. In some cases this drug helps: https://pillintrip.com/medicine/azor-anti-anxiety.

Rapid heartbeat is not always a symptom of any disease. Healthy people may be caused by nervous or physical stress. And its emergence can be triggered by both negative and positive emotional experiences. Increased heart rate provokes the release of adrenaline.

Minor physical activity, such as walking, jogging, climbing stairs, as well as prolonged power sports training. Such a condition is considered normal and does not require treatment. The elimination of external factors leads to the restoration of the usual rhythm. However, physicians distinguish and pathological tachycardia, which is caused by cardiovascular, endocrine and other diseases. In this case, in addition to palpitations, patients also have a number of associated symptoms:

Shortness of breath.
Dizziness.
Restlessness, anxiety.
Fainting states.
Perceptible in the neck area pulsation of blood vessels.
It should be noted that a child under 7 years of age has a consistently more frequent pulse rate than an adult, and reaches up to 120 bpm, which is considered normal.

In adolescents, tachycardia is a consequence of rapid growth of the heart and the mismatch of its size to the formed vascular system.

In older people, the pulse rate can be observed against the background of physical activity, as well as at rest. This is due to age-related changes, heart disease, endocrine system, increased pressure as a result of changes in the structure of blood vessels.

Classification of tachycardia
Depending on the causes that cause increased heart rate, they divide the physiological form of the pathology, which is an adequate reaction of the body to the effects of external factors. These should include:

Physical exertion.
Excessive emotional overstrain.
Acceptance of tonic agents and some medications, such as corticosteroid drugs, adrenaline, caffeine, atropine.
In addition, the rapid contraction of the heart muscle can provoke unfavorable climatic conditions, such as extreme heat, high levels of humidity.
Pathological tachycardia is a consequence of various diseases of the heart and vessels, malfunctions of the endocrine and autonomic system, and may develop because of

Dehydration of the body.
As a result of severe blood loss.
Against a background of high fever caused by infectious and viral diseases.
In addition, palpitations are noted in patients with anemia, hyperthyroidism, adrenal tumor, neurosis and psychosis. However, frequent causes of pathological tachycardia are:

Heart failure.
Myocardial infarction.
Coronary heart disease.
Congenital or acquired malformations.
And other pathologies of the organ.

Normally, the electrical impulse that induces the heart muscle to contract is originated in the sinoatrial node. When this process is disturbed, sinus tachycardia occurs. The number of heartbeats can range from 120 to 220 beats. It is observed in patients who have had a heart attack, suffering from angina pectoris, ischemia and other diseases of the CPS.

In addition to the constant palpitations, a person notes heaviness and pain behind the sternum, dizziness, shortness of breath, disturbed night sleep, decreased appetite, and a falling mood. Due to impaired blood supply to the organs and the lack of sufficient oxygen supply, some patients experience fainting, coldness of the extremities, and cramps.

If the impulse that excites myocardial contraction is formed outside the sinus node, then we are talking about ectopic tachycardia. There are several types of this pathology, depending on the place of formation of electrical activity. In ventricular tachycardia, in addition to a rapid pulse, whose number of beats reaches 220 per minute, is observed:

A squeezing sensation in the heart area.
Dizziness.
Loss of consciousness.
Atrial tachycardia is less common. The pathological condition occurs occasionally and can last from several days to months. It proceeds without pronounced symptoms, which in older patients may go unnoticed.

A common form of the pathology is arventricular tachycardia. Characteristic signs are:

Sudden onset of an attack with a duration of several minutes to a day.
A drop in blood pressure.
Sensation of throbbing in the vessels of the neck.
Choking.
Disturbance of consciousness.
This form of tachycardia is more common in females.
