Heart rhythm disorders

Arrhythmia is a disorder of the heart rhythm. Arrhythmia refers to a slowed or accelerated rhythm of the heart as well as various uncoordinated movements of the heart muscle, and thus the atria or ventricles. 

Atrial fibrillation is the most common heart disorder and is characterized by arrhythmia or heart rhythm disorder. The disease causes chaotic and irregular contractions of muscle fibers and thus loss of coordinated activity of the atria. At the same time, the heart weakens its pumping ability and at the same time, irregular and accelerated heart activity occurs. The disease is most common in people over 80 years of age, where it affects 15% of the population.
