The ballistocardiograph (BCG) is a measure of ballistic forces on the heart.^[1] Ballistocardiography is a technique for producing a graphical representation of repetitive motions of the human body arising from the sudden ejection of blood into the great vessels with each heart beat.^[2] It is a vital sign in the 1-20 Hz frequency range which is caused by the mechanical movement of the heart and can be recorded by noninvasive methods from the surface of the body. It was shown for the first time, after an extensive research work by Dr. Isaac Starr, that the effect of main heart malfunctions can be identified by observing and analyzing the BCG signal.^[3]

One Example of the use of a BCG is a ballistocardiographic scale, which measures the recoil of the persons body who is on the scale. A BCG scale is able to show a persons heart rate as well as their weight.

The term ballistocardiograph originated from the Roman ballista, which is derived from the Greek word ballein (to throw), a machine for launching missiles, plus the Greek words for heart and writing.

Yamakoshi K.AbstractSignificant advances in the field of biomedical instrumentation have continued to contribute towards improvements in the quality of clinical diagnosis and treatment, which could have important implications for health and welfare. Up to the present, progress in several topics has been reviewed within the In the Spotlight column, including new and noteworthy measurement methods [1], ballistocardiography revisited [2], wearable monitoring [3], and home healthcare technologies [4]. The present review deals with three notable topics from recent publications in the field of bioinstrumentation. These are: (1) new conducting polymer electrodes for in vivo bio-electrical measurements, (2) mHealth technology using mobile communication devices such as mobile phones and personal digital assistants (PDAs), and (3) non-invasive in vivo measurement of blood constituents. These topics are of recent or renewed interest and, where appropriate, progress since the previous reviews [1], [2] will be highlighted.

Ballistocardiography (BCG) is a non-invasive technology that has been used to record ultra-low-frequency vibrations of the heart allowing for the measurement of cardiac cycle events including timing and amplitudes of contraction. Recent developments in BCG have made this technology simple to use, as
