Title:
心電図情報処理装置及び心電図情報処理方法
Document Type and Number:
Japanese Patent JP4718033
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To compute dispersion in the R-R trend of an examee, dispersion time and duration with high accuracy even if the condition of an electrocardiogram signals collected are not sufficient. SOLUTION: A waveform portion that can be surely recognized as the QRS wave from an electrocardiogram collected from a subject is cut out (S2), and made a comparison standard waveform (S3), by comparing the standard waveform and a waveform to be processed (S4), the QRS waveform is detected with high accuracy (S5 and S6), continuous heartbeats in which heartbeats that are surely judged to be a QRS waveform continue are grouped, and by obtaining the R wave interval for the grouped continuous heartbeats, the R-R trend is measured (S11).
