Non-invasive risk stratification for sudden cardiac death by heart rate turbulence and microvolt T-wave alternans in patients after myocardial infarction
EP Europace, 08/08/2012
Sulimov V et al. – In patients who died from cardiovascular causes, microvolt T–wave alternans (mTWA), and TO values were significantly higher and turbulence slope (TS) values were significantly lower than in survivors, and the subgroup with sudden cardiac death (SCD) was characterized by significantly increased mTWA and TO values and decreased TS values. mTWA > 53.5 mcV at 100 b.p.m. was an independent significant predictor of SCD and increased risk of SCD by five–fold.
