title: Relation between severity of disease and impairment of heart rate variability parameters in patients with chronic congestive heart failure secondary to coronary artery disease.
abstract: The present data show that HR variability has a statistically significant, but moderate, correlation with clinical variables of severity of CHF. Therefore, HR variability analysis may be a new, important tool in the clinical assessment of CHF patients.
