Spectral analysis may detect early hypertension-related shifts before LVH; leaves open prognostic value or therapeutic implications pending longitudinal data.
Does spectral analysis of resting blood pressure and heart rate variability differ among normotensive controls, hypertensive patients without LVH, and hypertensive patients with LVH?
Spectral analysis of resting blood pressure reveals that low-frequency oscillations are altered in the time course of hypertension, providing complementary information on cardiovascular regulatory system changes.
