The Multipole Method is a recently developed method to describe time series with highly complex time evolution, such as cardiac rhythm. We hypothesized that applying this method in the analysis of heart rate variability (HRV) could provide valuable physiological information that usually cannot be extracted from the commonly used time and frequency domains(More)
BACKGROUND Contemporary implantable cardiac defibrillators (ICD) enable storage of multiple, preepisode R-R recordings in patients who suffered from ventricular tachyarrhythmia (VTA). Timely prediction of VTA, using heart rate variability (HRV) analysis techniques, may facilitate the implementation of preventive and therapeutic strategies. AIM To evaluate(More)
AIMS The density HRV parameter Dyx is a new heart rate variability (HRV) measure based on multipole analysis of the Poincaré plot obtained from RR interval time series, deriving information from both the time and frequency domain. Preliminary results have suggested that the parameter may provide new predictive information on mortality in survivors of acute(More)
