Is reduced heart rate variability associated with hypertension and blood pressure control?
Reduced heart rate variability is associated with hypertension and is more pronounced in patients with uncontrolled blood pressure, suggesting greater autonomic impairment.
Our study showed that cardiac autonomic nervous impairment, as demonstrated by reduced HRV, is significantly associated with HTN. Decreased HRV was more evident in uncontrolled BP than in controlled BP group.
