ABSTRACT

Better knowledge of mechanisms which perpetuate heart failure and promote progression and death in patients with these sicknesses, has led to find a better medical treatment to improve the functional status, decrease mortality and improve life span, avoiding the progression of ventricular dysfunction. Mortality reduction due to the disease progression has led to evident arrhythmic mortality show by sudden death. Aspects involved in the genesis and pathophysiology of sudden death in patients with chronic-heart failure; are reviewed in this paper. Special reference to mechano-electrical feedback is considered.
