Sleep disordered breathing (SDB) is common in heart failure and ventilation is known to ini??uence heart rate. Our aims were to assess the ini??uence of SDB on heart rate variability (HRV) and to determine whether central sleep apnea (CSA) and obstructive sleep apnea (OSA) produced different patterns of HRV.
