On the Estimation of T-Wave Alternans Using the Spectral Fast Fourier Transform Method

BACKGROUND: T-wave alternans (TWA), has been associated with increased vulnerability to ventricular tachyarrhythmias and sudden cardiac death (SCD). However, both random (white) noise and (patho)physiologic processes (i.e. premature ventricular contractions [PVCs], heart and respiration rates) may h...
