Title:
Handling of ectopic beats in heart rate variability analysis using the heart timing signal
IFMBE Proceedings MEDICON and HEALTH TELEMATICS 2004 "X Mediterranean Conference on Medical and Biological Engineering"
Type:
conference paper
Abstract:
The problem of analyzing heart rate
variability in the presence of ectopic beats is
revisited. Based on the IPFM model and the closely
related heart timing signal, a new technique is
introduced which corrects for the occasional presence
of such beats. The correction technique, which
involves the occurrence times of a certain number of
beats preceding the ectopic, is computationally very
efficient. Based on actual heart rate data, the results
suggest that the power spectrum, and related clinical
indices, are more accurately estimated.
