DETERMINING RESPIRATORY RATE AND VOLUME FROM ECG R-WAVE AMPLITUDE MODULATION.

Abstract:

Various ECG electrode placements were investigated to determine which location would yield an R-wave amplitude modulation with the highest possible degree of correlation to respiratory volume. Each subject breathed into a spirometer to generate an electrical signal proportional to instantaneous respiratory volume. This signal was simultaneously recorded with the various electrocardiographic signals sensed by the electrodes attached to the subject. This information was then digitized and a plot of R-wave amplitude versus respiratory volume was made and the coefficient of correlation was computed for each set of data. Author
