Allorhythmia

Allorhythmia (from the Greek allo - “other” and rhythmos - “rhythm”) is a disturbance of the heart rhythm in which extrasystoles occur that are not associated with the main rhythm of the heart.

Allorhythmia is characterized by the appearance of premature contractions of individual sections of the heart muscle, which leads to a disruption in the sequence of heart contractions. These additional contractions are called extrasystoles. They occur before the next sinus contraction and are not associated with the main rhythm.

The causes of allorhythmia can be different: myocardial ischemia, cardiomyopathy, damage to the conduction system of the heart, and taking certain medications. The most dangerous are ventricular arrhythmias, which can lead to ventricular fibrillation and sudden cardiac death.

To diagnose allorhythmia, ECG, ECHO-CG, and Holter monitoring are performed. Treatment depends on the type of arrhythmia, its causes and the severity of its manifestations. This may include drug therapy, catheter ablation, or implantation of a pacemaker or defibrillator.

Thus, allorhythmia is a disturbance of heart rhythm associated with the occurrence of extrasystoles. Timely diagnosis and adequate treatment of this condition are important to prevent life-threatening arrhythmias and their consequences.

Allorhythmic rhythms. Basics.

Allorhythmia, also known as periodic "waning" of the heart rate, is caused by a disruption of the normal cycle of excitation and contraction of the heart. This condition can be caused by various reasons, but primarily it is characteristic of organic diseases of the heart and nerves. The most common forms of allorhythmia are atrial fibrillation (atrial fibrillation), paroxysmal supraventricular tachycardia and extrasystoles.

Normally, under the influence of an electrical impulse, a wave of excitation (depolarization) is generated in the heart muscle, which moves at a speed of approximately 120 to 220 beats per minute (“mesenteric rhythm”) and then turns into contraction (repolarization). After a period of rest, the heart is ready for a new cycle.
