Nonlinear HRV parameters may aid VT/VF forecasting in ICD patients; hypothesis-generating and requires prospective validation before clinical adoption.
Can symbolic dynamics and finite-time growth rates of beat-to-beat intervals forecast the onset of life-threatening cardiac arrhythmias in ICD patients?
Non-linear heart rate variability parameters derived from symbolic dynamics and finite-time growth rates may help forecast life-threatening arrhythmias in ICD patients.
