In a healthy person, the heartbeat is quite even. As a rule, blows are not felt. At night, there is a slowdown in the rhythm to fifty to sixty beats per minute. During exercise, the heartbeat, on the contrary, becomes more frequent. The rhythm of the beat depends mainly on the sinus node. In turn, the activity and condition of the node itself depend on the state of the nervous system. With violations in the sinus node, cardiac arrhythmia can occur.
Symptoms manifest in varying degrees of intensity depending on the severity of the condition. With physical or emotional stress, the rhythm can increase to one hundred twenty-one hundred and fifty beats per minute. Such cardiac arrhythmia, as a rule, does not require the use of special therapeutic measures. To normalize the rhythm, resting, taking light sedatives is enough.
What is cardiac arrhythmia?
This condition is an abnormal rhythm of contractions. Cardiac arrhythmia is characterized by the presence of discomfort in the region of the heart, a feeling of a strong heartbeat, or, conversely, interruptions in activity. In some cases, the condition may be accompanied by suffocation and pain.
Cardiac arrhythmia can occur due to various reasons. Among the main should be called arterial hypertension, coronary artery disease, head injury, thyroid pathology. Vascular diseases, defects, inflammatory heart diseases, and dystrophic changes in the heart muscle also contribute to the onset of the disease . The causes can be diabetes and infection.
Often, cardiac arrhythmia occurs in women during pregnancy. In such cases, the condition is caused by the presence of congenital malformations, a hereditary predisposition. The disease can occur in a healthy woman. In this case, the condition is determined by the physiological characteristics of pregnancy. Due to the fact that the fetus grows and develops, the load on the mother’s heart intensifies, as the need for oxygen increases. With the growth of the child, certain changes occur in the position of the mother's organs. Along with this, the pressure on the heart rises, and it becomes more difficult for the body to work. This causes a rhythm disturbance. In addition, cardiac arrhythmia in pregnant women may be associated with hormonal changes, as well as changes in the nervous autonomic system.
Among the varieties of the disease, tachycardia, extrasystole, bradycardia are distinguished. There is also heart block , atrial fibrillation.
For tachycardia is characterized by an increase in the frequency of contractions (over ninety strokes). With bradycardia, the pulse slows down and becomes less than normal (less than sixty beats). Extrasystole means "additional" contractions. Atrial fibrillation is characterized by a random irregular rhythm. Blockade is a condition in which an impulse cannot pass through certain areas of the muscle. Blockade can cause cardiac arrest.
In the presence of discomfort, discomfort against a background of seizures, it is necessary to consult a specialist.
