Arterial fibrillation or flutter detector for use in e.g. implantable heart pacemaker, has evaluation unit dividing arterial signal into sequential sections, where peak-to-peak amplitude of signals is smaller than comparison value

摘要

The detector has an evaluation unit (EVAL) formed to divide an arterial signal into multiple sequential sections. Each section of the arterial signals is at a point of time, and averaged together to form an averaged arterial signal in order to determine peak-to-peak amplitude of the averaged arterial signals. The peak-to-peak amplitude of the averaged arterial signals is compared with a comparison value, and is smaller than the comparison value to produce an arterial fibrillation or flatter suspicion signal.
