Long QT syndrome and its role in THE development of severe heart rhythm disturbances and sudden death
https://doi.org/10.51523/2708-6011.2016-13-3-3
Abstract
The article presents information from national and foreign sources on the significance of long QT syndrome on the electrocardiogram as a predictor of severe heart rhythm disturbances and sudden death. It considers the pathologic physiology of the present syndrome, the deficiency of intracellular magnesium plays an important part in its mechanism, which determines the therapeutic aspects leading to normalization of the QT interval
