A he althy person has a fairly regular heartbeat. As a rule, shocks are not felt. At night, there is a slowing of the rhythm to fifty to sixty beats per minute. During exercise, the heartbeat, on the contrary, quickens. The rhythm of beats depends mainly on the sinus node. In turn, the activity and state of the node itself depend on the state of the nervous system. With abnormalities in the sinus node, cardiac arrhythmia may occur.
Symptoms appear 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 to 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, rest is enough, taking light sedatives.
What is cardiac arrhythmia?
This condition is a contraction rhythm disorder. Cardiac arrhythmia is characterized by the presence of unpleasant sensations in the region of the heart, a feeling of a strong heartbeat, or, conversely, interruptions in activity. In some cases, the statemay be accompanied by choking and pain.
Cardiac arrhythmia can occur due to various reasons. Among the main ones should be called arterial hypertension, ischemic disease, TBI, thyroid pathology. The occurrence of the disease is also facilitated by vascular diseases, defects, inflammatory diseases of the heart, degenerative changes in the heart muscle. Both diabetes and infection can be causes.
Frequently, cardiac arrhythmia occurs in women during pregnancy. In such cases, the condition is caused by the presence of congenital malformations, hereditary predisposition. The disease can also occur in a he althy 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 increases, 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 also increases, it becomes more difficult for the body to work. This causes a violation of the rhythm. In addition, cardiac arrhythmia in pregnant women may be associated with hormonal changes, as well as changes in the autonomic nervous system.
Among the varieties of the disease are tachycardia, extrasystole, bradycardia. There is also heart block, atrial fibrillation.
Tachycardia is characterized by an increase in the frequency of contractions (over ninety beats). With bradycardia, the pulse slows down andbecomes less than normal (less than sixty beats). Extrasystole is understood as "additional" contractions. Atrial fibrillation is characterized by erratic non-rhythmic frequency. Blockade is a condition in which the impulse cannot pass through certain areas of the muscle. Blockade can cause cardiac arrest.
If there is discomfort, discomfort on the background of seizures, you need to contact a specialist.
