Heart Force Medical Inc. (HFM), a private company, has invented and has patents pending for the digital Ballistocardiograph (dBG(TM)). The dBG 300, which is already approved in Canada and the United States, captures the movement of the heart during each cardiac cycle (heart beat). This movement (acceleration and force) is sensed by an accelerometer aligned to the three principal axes and displayed on a computer screen using HFM's proprietary software. Preliminary evaluation has determined that a 10-30 second recording of the dBG waveform is sufficient for a detailed analysis of cardiac performance. The Heart Force dBG 300 device is a non-invasive, standalone, portable unit and contains sophisticated digital sensors and proprietary software.
