- W2334648905 abstract "Introduction: It is well known that many patients with heart failure have sleep apnea syndrome (SAS). we could confirm the existence of SAS by fractal analysis of heart hate variability (HRV). (Fig.) Objectives: In this study, we investigated whether the type of SAS influences this abnormal power. Methods: We studied 77 consecutive patients that performed 24-hour ambulatory electrocardiographic recordings and sleep apnea examination for the same period between April 2004 and September 2007 (mean age 68 years, 14 female). The basic heart rhythm was sinus rhythm in 61 cases, atrial fibrillation (Af) in 16 cases. HRV analysis performed by fast Fourier transform analysis and displayed results by the method to calculate a fractal dimension. We reviewed presence of the abnormal power in frequency band from 0.01Hz to 0.04Hz. Results: Central type SAS (CSAS) showed spear-shaped abnormal power increase. Obstructive or Mixed type SAS showed more broad shape abnormal power. Hypopnea dominate SAS tended to present no abnormal power. Patients with Af also tended to showed no abnormal power." @default.
