Periodic variations of the thoracic bioimpedance due to breathing and heartbeating carry confidential information that is used for pacing rate control in rate-adaptive pacemakers. The respiratory parameters--the respiration rate and tidal volume--are detected from the filtered breathing signal component (0.1 to 1.0 Hz), and are used for fuzzy feed-forward adaptive control of the pacing rate to meet the needs of the organism. The cardiac parameters--the actual heart rate and stroke volume--are… CONTINUE READING
