- Beats - heart rhythm disturbances
- Types and causes of
As our heart is reduced
The human heart is reduced by the action of pulses that occur in its muscles. This property is called an automaton. The muscles that provide such properties to form in the heart of beams and nodes, all together it makes conducting system. Cardiac conduction system is presented:
- sinoatrial node (in the right atrium) - the source of the physiological cardiac rhythm, which runs to the branch node atrioventricular;
- atrioventricular node (in the atrial septum to the right), which are carried out by branch pulses to the ventricles; It can generate nerve impulses when not working atrionector.
In addition, the heart has additional pathways that connect the atria and ventricles to bypass the atrioventricular node, which are important during the pulses to the ventricles in case of defeat this site.
What beats, its types and causes
Beats - heart rhythm disturbance, characterized by the emergence of single or pair of premature heart beats (extrasystole), caused by the excitation of the myocardium. Three or more of the following one after the other beats are considered as short-term attack of paroxysmal tachycardia.
Depending on the place of occurrence of "excess" of nerve impulses to the atrial arrhythmia share, atrioventricular (nodal) and ventricular. In very rare cases, additional excitation occurs in a physiological pacemaker - the sinoatrial node.
Beats may occur from various causes: violation of the nervous regulation of cardiac activity, various diseases of the heart muscle, chronic poisoning by some poisons, and so on, as well as a combination of different reasons.
Arrythmia related to the nervous regulation of cardiac activity may occur after nervous stress, diseases of other internal organs (liver, stomach, and so on) or the defeat of the nervous system (eg trauma and brain tumors).
Inflammatory and dystrophic (for circulatory disorders) changes in the myocardium (heart muscle) can also cause the appearance of arrythmia. It may be myocarditis (inflammation of the heart muscle), myocardial dystrophy (metabolic abnormalities in the heart muscle), ischemic heart disease

and so on.
The appearance of extrasystoles may occur to the damage ratio of ions of potassium, sodium, calcium and magnesium in myocardial cells and in the extracellular medium. Such disturbances adversely affect the conduction system of the heart.
As manifested arrhythmia
Generally, arrhythmias, even frequent, have no or little effect on hemodynamics (blood flow within the heart). This is explained by the fact that after the arrythmia is heartbeat increased strength.
Beats may be asymptomatic, and the patient learns about it only from the doctor. In some cases, the patient feels a push in the chest, pulsation in the epigastric region, and the fading sense of disruptions in the heart, resembling a rapid decrease in the sense of an aircraft or a lift. Sometimes there is a feeling of short, 1-2 seconds of cardiac arrest, followed by the sensation of a strong blow to the chest wall. In some cases, these feelings are accompanied by short-term acute pain in the heart.
With the defeat of myocardial arrhythmia accompanied by a feeling of shortness of breath, weakness and dizziness

Diagnosis of arrhythmia
Diagnosis is based on patient complaints, data on the presence of any heart disease

. Additionally performed electrocardiography. If the normal ECG does not reveal ekstasistoly then held daily minitorirovanie (ECG during the day). In addition, a comprehensive examination of the patient in order to identify the causes of arrhythmia.
Treatment of arrhythmia
Treatment of arrhythmia is to eliminate the underlying disease and to restore normal heart rhythm.
Atrial and atrioventricular and ventricular arrythmia I and II degree, which do not cause unpleasant effects in patients, treatment can not be. If a patient feels unpleasant phenomena of the heart with waves, he prescribed anti-anxiety medications.
In cases where the treatment of the underlying disease does not resolve the beats, are appointed by antiarrhythmic drugs. They matched each patient individually, taking into account all the peculiarities of a particular drug. Treatment of chronic leaking arrhythmia should be constant, since after the abolition of the received funds arrhythmia usually renewed.
Attention! When the "extra" heartbeats should immediately consult a doctor, as they may be a sign of serious heart disease.
