What is an arrhythmia?

With arrhythmia, the normal heart rhythm is disturbed due to the uneven appearance of impulses in the sinus node. Correct functioning of the cardiac conduction system regulates the blood supply of all organs and tissues. If there are violations in the conductivity, they are observed in the blood supply.

Normally, the heart makes 60-90 strokes per minute. Changes in heart rate include:

Sinus tachycardia is a regular frequent heartbeat of more than 90 beats per minute. It happens with physical exertion, with an increase in temperature and a number of other conditions, and then it is the norm. Also the heart palpitations are accompanied usually by a hyperfunction of a thyroid gland, an anemia.

Sinus bradycardia heartbeat less than 60 per minute. Characteristic for athletes.
Ectopic contractions of the heart atrial fibrillation; the contractions do not occur in the sinus node, but in other areas of the conduction system of the heart (atria, ventricles, etc.) and occur in most people during the day.

Types of cardiac arrhythmias

Arrhythmias are divided into ventricular and supraventricular. The type of arrhythmia depends on the site of the conducting cardiac system, on which the failure occurs. Arrhythmias are usually not dangerous for life, but can cause discomfort (a sense of fear and anxiety, weakness, increased sweating). Ventricular arrhythmias are fraught with very severe hemodynamic disorders, can lead to death.

Symptoms of heart rhythm disturbances

Some types of arrhythmias are asymptomatic, they can be detected only on routine medical examinations.

Symptoms of other cardiac arrhythmias depend on their type and intensity. Common symptoms are:

  • Heart palpitations;
  • Dizziness;
  • Dyspnea;
  • Fainting (loss of consciousness);
  • Pain in the chest;
  • Weakness.

If you have an arrhythmia, treatment should be immediate. Self-medication should be ruled out. At home, therapy, for example, sinus arrhythmia reduces to taking Validol and so on, but the symptoms are removed, and the causes are not eliminated. Effective treatment of the disease can only be done by a good cardiologist.
