OBJECTIVE: A meta-analysis of the value of microvolt T-wave alternans (MTWA) testing for test severe arrhythmic events was conducted to predict mortality in heart failure patients.METHODS: Prospective studies of the predictive value of exercise-induced MTWA published between January 1990 and February 2014 were retrieved.Heterogeneity was analyzed with x2 and I2.Pooled hazard ratio (HR) as the effect indicator and 95%confidence interval were used to estimate the association of MTWA and risk of severe arrhythmic events and death by fixed effect model (inverse variance method).
