Heart rhythm disturbance

The work of the myocardium is divided into two phases - systoles and diastoles. Violation of the rhythm of the heart, that is, failures in the sequence of systole and diastole and rhythmicity of work are called arrhythmia. In the case of a decrease in the diastole period, the myocardium does not have time to recover, and with a decrease in the systole period, the body is not fully provided with nutrients and a sufficient volume of blood.

Violation of the rhythm of the heart provides for a diverse and complex classification. With sinus bradycardia, the normal rhythm drops below 60 cuts per minute, while the cardiac complex on the ECG remains unchanged. In this case, the violation of the rhythm of the heart can be a consequence of diseases of the thyroid gland, hypothermia, brain tumors, fungal poisoning, etc.

Slow heart rhythm is often observed in athletes. With sinus tachycardia , there are more than 100 beats per minute. The heart complex also does not change.

Violation of the heart rhythm occurs after stressful situations, poisoning, physical exertion, due to heart failure and thyroid disease. Violation of the rhythm of the heart with an emergency reduction of the myocardium is called extrasystole.

The most dangerous violation of the rhythm of the heart is called paroxysmal tachycardia, in which there is a sharp and causeless increase in the work of the heart to 200 beats per minute. The attack can last for several hours and ends suddenly. Atrial fibrillation is an absolutely wrong rhythm and is also the most dangerous form of the disease. There are no reliable reasons for the onset of the disease to date.

Violation of the rhythm of the heart in children can develop as a result of anomalies of development. It is believed that the causes of arrhythmia are disorders of the nervous and endocrine regulation of the rhythm, organic and functional factors, as well as acquired anomalies of the anatomical structure.

Diagnosis of heart rhythm disturbances is carried out on the basis of ECG, Holter monitoring, echocardiography. In some cases, electrophysiological methods of diagnosis are used.

Heart rhythm disturbance: treatment

Treatment of violations of heart rate irregularities largely depends on the type of disease, possible causes and other factors. Therapy is prescribed only after careful examination and under full medical supervision. Physicians should be treated with all suspicions of a cardiac muscle disruption. Untimely and ineffective treatment can lead to death.

Often, arrhythmias occur against a background of psychogenic disorders, such as various neuroses, corticovascular reflexes. Therefore, the therapy in these cases is aimed at eliminating the factors that led to the violation of the heart. With organic heart lesions, such as myocarditis, myocardiopathy,
Heart diseases, the treatment of the underlying disease is prescribed. In toxic

Funds, as well as traumatic damage to the heart muscle. An important role in heart rhythm disturbances is played by age-related changes, which are expressed in the weakening of the nervous effects on the heart and the decrease in the automatism of the sinus node. Treatment in this case is aimed at eliminating negative factors.
