| Summary: | An algorithm for the real-time measurement of the fetal and maternal RR intervals
from a single-lead abdominal signal has been developed on a low power TMS32010
digital signal processor development system. The algorithm is based on a combination
and modification of earlier techniques which have been proposed to perform similar
processing. The performance of the algorithm is improved by the incorporation of
validation procedures which enable the algorithm to continue operation despite
temporary data loss during maternal movement. The reliability of the R-wave
detection is determined from information tagged to the measured R-R intervals
indicating the signal condition at the time of detection. These tags are then used as a
basis for error correction and the measurement of the algorithm performance. The
performance achieved from tests on active pregnant women shows the possibility of
implementing the above system for ambulatory use |
