May signal heightened CV vulnerability in euthymic bipolar patients; leaves open prognostic value and intervention targets.
Is heart rate variability altered in euthymic bipolar patients compared to age- and sex-matched controls?
Euthymic bipolar patients exhibit markedly low heart rate variability at rest, indicating altered cardiovascular autonomic function.
Cohen et al. (2003) studied this question.
