HRV may associate with HF severity and prognosis in LVD; leaves open its added value beyond conventional markers.
Does abnormal age-adjusted heart rate variability predict cardiac death and heart failure severity in patients with left ventricular dysfunction?
Age-adjusted heart rate variability serves as a useful non-invasive marker for assessing heart failure severity and predicting cardiac death in patients with left ventricular dysfunction.
