The electronic measuring system for seismocardiography with separate QRS detection

The Quantitative seismocardiography (Q-SCG) opens a new field of cardiovascular dynamics examination. Using this absolutely non-invasive method, a new field of monitoring heart rate variability was opened up. Systolic forces as well as heart rate variability in relation to changes in external stimuli are registered. Q-SCG probably offers a more complex view of both isotropic and chronotropic heart functions. It will be suitable for: examining operators exposed to stress; for assessing the effect of work, fatigue and mental stress; for monitoring persons as part of disease prevention. A new electronic system for acquisition of data for noninvasive Q-SCG and signal processing was developed. For better Q-SCG signal evaluation, also the QRS complex is detected and simultaneously registered.
