BCG chair measurements

Examples of measured waveforms from four subjects

BCG from four subjects

EMFi force sensitive sensors measured the ballistocardiographic (BCG) waveforms from four test subjects for this illustration. The two subjects on top were healthy and the two subjects in the bottom had suffered from myocardial infarction in the past. The signals from top to bottom are electrocardiography (ECG), impedance cardiography (ICG, not measured with the ProHeMon chair but wit a Circmon device), BCG from the back of the chair and BCG from the seat part of the chair.
