The clinical course of this patient's case. SAM = sleep apnea monitoring, HF = heart failure, ASV = adaptive servo ventilation, IV = intravenous injection, DIV = drip infusion into vein, PEEP = positive end-expiratory pressure, PS = pressure support.

Fig. 1 shows the clinical course of this patient after hospital admission.
RDI values obtained from the pacemaker over time. SAM = sleep apnea monitoring, RDI = respiratory disturbance index, HF = heart failure ASV = adaptive servo ventilation.

Fig. 2 shows the RDI records from the SAM algorithm of this patient. ASV therapy was initiated on disease day 13 (Fig. 2 asterisk).
Correlations between RDI and AHI values. RDI = respiratory disturbance index, AHI = apnea hypopnea index.
