Challenges reliance on traditional HRV indices for elderly prognosis; hypothesis-generating for pattern-specific risk models.
Cohort (n=290)
p-value: p=0.019
Stein et al. (2005) conducted a cohort in Elderly subjects in normal sinus rhythm (n=290). Abnormal heart rate variability (HRV) patterns vs. Normal HRV patterns was evaluated on Mortality (p=0.019). Abnormal heart rate variability patterns that elevate many traditional HRV indices are significantly associated with a higher risk of mortality in the elderly (P=0.019).
