Arrhythmia

Arrhythmia is any deviation from the normal heart rhythm (sinus rhythm). The natural pacemaker of the heart, the sinoatrial node, located in the wall of the right atrium, under the influence of the autonomic nervous system controls the speed and rhythm of heart contractions. It generates electrical impulses that enter the atria and ventricles through special conduction cells of the heart, causing them to contract at a normal rhythm.

Arrhythmia occurs due to disturbances in the generation or conduction of these impulses. It can be intermittent or constant. Arrhythmias include: extrasystole, ectopic tachycardia, fibrillation and heart block (often accompanied by a slowing of the rhythm).

The main manifestations of arrhythmia are rapid heartbeat, shortness of breath and chest pain. In severe cases, Adams-Stokes syndrome or cardiac arrest may occur.

The causes of arrhythmia can be associated with heart disease, and also occur for no apparent reason.

Arrhythmia is any deviation from the normal rhythm of the heart. A healthy person does not have a pulse - it is provided by a special cardiac driver located in the right atrium. The main function of the heart pacemaker is to transmit electrical impulses to special cells of the heart, including sinus rhythm. When the body is healthy, the heart beats

Arrhythmia is any deviation from the normal heart rhythm. Ideal sinus rhythm (or sinus arrhythmia) occurs when the heart beats evenly and slowly (60-100 beats per minute). Any other heart rhythm is an arrhythmia.

The normal pacemaker of the heart is the sinoatrial (SA) node, located in the upper wall of the right atrium. This node controls the speed and rhythm of heart contractions, generating electrical
