Electronic bathroom scales are an easy-to-use,
affordable mean to measure physiological parameters in
addition to body weight. They have been proposed to obtain the
ballistocardiogram (BCG) and derive from it the heart rate,
cardiac output and systolic blood pressure. Therefore, weighing
scales may suit intermittent monitoring in e-health and patient
screening. Scales intended for bioelectrical impedance analysis
(BIA) have also been proposed to estimate the heart rate by
amplifying the pulsatile impedance component superimposed on
the basal impedance. However, electronic weighing scales
cannot easily obtain the BCG from people that have a single leg
neither are bioimpedance measurements between both feet
recommended for people wearing a pacemaker or other
electronic implants, neither for pregnant women.
We propose a method to detect the heart rate (HR) from
bioimpedance measured in a single foot while standing on an
bathroom weighting scale intended for BIA. The electrodes
built in the weighing scale are used to apply a 50 kHz voltage
between the outer electrode pair and to measure the drop in
voltage across the inner electrode pair. The agreement with the
HR simultaneously obtained from the ECG is excellent. We
have also compared the drop in voltage across the waist and the
thorax with that obtained when measuring bioimpedance
between both feet to compare the possible risk of the proposed
method to that of existing BIA scales. |
