Heart Rate Fragmentation: A New Approach to the Analysis of Cardiac Interbeat Interval Dynamics

Heart Rate Fragmentation: A New Approach to the Analysis of Cardiac Interbeat Interval Dynamics

Background: Short-term heart rate variability (HRV) is most commonly attributed to physiologic vagal tone modulation. However, with aging and cardiovascular disease, the emergence of high short-term HRV, consistent with the breakdown of the neuroautonomic-electrophysiologic control system, may confo...
