The emerging epidemic of obesity in developing countries. Studies addressing the molecular and functional basis of arrhythmogenesis in relevant animal models of metabolic disorders are just emerging and significant gaps in knowledge remain, warranting further research investigations. Obesity is marked by accumulation of adipose tissue associated with a variety of adverse adaptations including dyslipidemia or abnormal levels of serum free fatty acidsincreased secretion of pro-inflammatory cytokines, fibrosis, hyperglycemia, and insulin resistance, that will cause electrical remodeling and thus predispose to arrhythmias.
