Automatic Concealed Heart Rate Detection from the BCG in Seated Position

Abstract: Abstract-Continuous monitoring of health state is important in elder and chronically ill (but otherwise not critical) patients. Ideally, the patient should not be aware of being continuously monitored. This study describes an automatic and non-conscious heart rate monitoring system based on the ballistocardiogram (BCG). The bi-axial BCG can be recorded by two piezoelectric force sensors and high-gain amplifiers. Digital signal preprocessing has been implemented to increase the SNR and an algorithm to automatic… Show more

“…During sleep, the pressure signal generated by chest and abdominal vibrations of the human body includes respiratory, BCG, and noise components. The frequency of the respiratory signal is about 0.3 and 2 Hz, and the highest frequency component of the BCG vital sign in the 1–20 Hz frequency range [ 21 ]. The noise components include human myoelectric noise, 50 Hz/60 Hz power-line interference, and body motion noise.…”

“…We compared frequency variation related to heart and lung activity detected by our system with the other representing cardiopulmonary state physiology signal BCG, which also reflects the respiratory behavior variation [17]. We obtained the BCG data and frequency variation due to electromagnetic induction by our designed system when the target object is at normal breath state and holding breath state.…”
