In our case ventricular heterogenity is the diversity of the ventricle’s heart muscle cells’ bioelectrical property. This heterogenity is present even in healthy cases as predetermined (basically tense connection between the cells). But, in pathological cases the heterogenity of the cells grow and the aligned working of the heart muscle cells becomes worse. This calls forth the lability of the bioelectrical phenomenons. This instability increases the risk for developing dangerous ventricular arrhythmias, hereby increasing the risk for Sudden Cardiac Arrest.
