Key result
Ambulatory ECG-based T-wave alternans analysis serves as a marker of risk for ventricular fibrillation by exposing latent electrical instability during daily activities.

May aid sudden death risk stratification in cardiac disease; leaves open need for prospective outcome trials before adoption.
Does ambulatory ECG-based T-wave alternans analysis improve sudden death risk stratification in patients with cardiac disease?
Ambulatory ECG-based T-wave alternans analysis provides a noninvasive method for sudden death risk stratification in patients with cardiac disease.
Verrier et al. (2005) conducted a review in Ventricular fibrillation and arrhythmias. Ambulatory ECG-based T-wave alternans (TWA) analysis was evaluated. Ambulatory ECG-based T-wave alternans analysis serves as a marker of risk for ventricular fibrillation by exposing latent electrical instability during daily activities.
