Abstract

Classical parasystoles are described of which the main signs are: variation of the coupling intervals, multiplicity of interectopic intervals, presence of fused ECG complexes. A detailed description of intermittent parasystolia is given. It differs from the classical form by the absence of PS-intervals and fixation of the fused PS-interval with impulses of the main rhythm. The possible mechanisms of fusion of the main and the parasystolic rhythms are described in detail. A detailed table of differential diagnosis of extrasystole and parasystole is given.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
