Structural abnormalities or electric changes in the cardiomyocytes can impede impulse formation or change cardiac propagation, therefore facilitating arrhythmias. Arrhythmogenic mechanisms can arise in single cells (automaticity, triggered activity), but other mechanisms require multiple cells for arrhythmica induction (re-entry).

Arrhythmogenic mechanisms can arise in single cells (automaticity, triggered activity), but other mechanisms require multiple cells for arrhythmica induction (re-entry). We briefly discuss the pathophysiological mechanisms of the main causes of arrhythmia. <Cite>Coronel</Cite> | ||
