There are cases when suddenly your heart starts to knock somehow wrong: too slowly or quickly, or heart beats alternate with different time intervals, or there may be an unnecessary contraction and so forth. In medical practice, such sudden-onset conditions are called arrhythmias of the heart. Scientists explain such changes in the heart's work with malfunctions in its conduction system, which provides regular and orderly contractions of the heart muscle. There is also a second group of diseases in this system - cardiac blockade, according to the Internet edition for girls and women from 14 to 35 years old Pannochka. net Some of the cardiac blockages can go unnoticed for a person. Often, blockades indicate the existence of another heart disease. The most severe blockade can manifest as a changed rhythm and contractility of the heart. In most cases, these diseases pose a threat of impaired cardiac function or the occurrence of severe complications of other organs. In addition, they sometimes are themselves a complication of another serious disease.

According to statistics, cardiac arrhythmia in humans is the cause of death in about 15% of all heart diseases. Therefore, the diagnosis, treatment and study of a disease such as cardiac arrhythmia, is engaged in a specialized cardiological section - arrhythmology.

What is the arrhythmia of the heart?.

Each stroke of the heart is accompanied by a sequential contraction of its parts, such as the atrium and ventricles. Abbreviations occur in the same amount of time and follow strictly one after another. When there is a violation of the sequence, rhythmicity or frequency of contractions of the cardiac divisions, this condition is called arrhythmia.

Why arrythmia of the heart?.

To provoke the arrhythmia of the heart in a healthy person can such factors as:.

overeating (abundant food);.

consumption of coffee and alcoholic beverages;.

close clothing;.

emotional stress / agitation;.

permanent constipation;.

a bite of an insect;.

some types of medicines.

Also arrhythmia of the heart can be observed in patients diagnosed with diabetes mellitus, which is combined with increased blood pressure or fullness. In women, often PMS is accompanied by a feeling of suffocation, arrhythmia and pain in the heart.

Often there are cases when the onset of cardiac arrhythmia was triggered by hereditary factors, as well as complications after cardiac surgery. It can also be a symptom of a number of other diseases:.

myocarditis;.

heart disease, ischemia or heart failure;.

thyroid disease or a number of other hormonal disorders;.

mitral valve prolapse.

What happens during an arrhythmia?.

A special conductive heart system provides the right heart rhythm. This system includes specialized cells that produce and conduct electrical pulses that control the sequential contraction of the cardiac muscles.

Starts a heartbeat pulse that is formed in the area of ??the upper right atrium, - the so-called pacemaker. Responsibility for heartbeat at 60-80 beats / min. lies exactly on the driver of the rhythm (sinus node).

Then the signal reaches the atrium, causes it to contract and then spreads to the ventricles. Due to the fact that all the cells of the conducting system have electrical activity, sometimes the impulse from some part of this system prevails over the impulse - the driver of the rhythm. There are times when a single pulse can cause a couple of heartbeats, and it also happens differently - not every impulse can cause contractions. Both in the first and in the second case this can lead to different types of disturbance of the heart rhythm.
