title: [The role of T-wave alternans in prognosis of risk of sudden cardiac death].
abstract: The literature review contains data dedicated to one of tools of stratification of risk of fatal arrhythmia - detection of T-wave alternans (TWA). Methods of determination of TWA, problems of results interpretation, mechanism of the TWA genesis, and its clinical meaning in different cardiovascular diseases are considered. Special attention is paid to the role of TWA in the identification of the patients who require cardioverter-defibrillator implantation.
