Beat-to-beat variability of QRS duration
Computers in Cardiology 1997, 2002Visual analysis has shown an increased beat-to-beat variability of QRS-duration (QDV) in patients with ventricular tachycardias (VT). The aim of this study was to develop an automatic algorithm for QDV analysis and to assess the contributions of high- and low-frequency components.
