“…Although the BCG signal was a popular method for monitoring heart activity in earlier days [13], [14], nowadays, the ECG signal is the standard method used by clinical personnel for monitoring heart activity and diagnosing many cardiovascular disorders. As a result, we wanted to establish a direct mapping between the measured BCG signal and the ECG signal.…”

“…An alternative method for monitoring heart activity is ballistocardiography (BCG), a non-invasive technique that used to be popular in earlier years for recording movements of the body caused by ventricular pump activity [12]- [14]. Since BCG is a mechanical signal, it can capture much richer information about the mechanical aspects of the heart activity, whereas the ECG signal records only the initiation of the myocardial contractions.…”

In this preliminary study, we investigate the potential use of smartphones as portable heart-monitoring devices that can capture and analyse heart activity in real time. We have developed a smartphone application called "Medical Tricorder" that can exploit smartphone's inertial sensors and when placed on a subject's chest, it can efficiently capture the motion patterns caused by the mechanical activity of the heart. Using the measured ballistocardiograph signal (BCG), the application can efficiently extract the heart rate in real time while matching the performance of clinical-grade electrocardiographs (ECG). Although the BCG signal can provide much richer information regarding the mechanical aspects of the human heart, we have developed a method of mapping the chest BCG signal into an ECG signal, which can be made directly available to clinicians for diagnostics. Comparing the estimated ECG signal to empirical data from cardiovascular diseases, may allow detection of heart abnormalities at a very early stage without any medical staff involvement. Our method opens up the potential of turning smartphones into portable healthcare systems which can provide patients and general public an easy access to continuous healthcare monitoring. Additionally, given that our solution is mainly software based, it can be deployed on smartphones around the world with minimal costs.

“…A study from Dock [104], reported that 92 % of 152 angina patients had an abnormal ballistocardiogram. Relevant results were published by Scarborough in [110], a study including 191 angina patients, reporting that 75.4 % of them had abnormal ballistocardiograms, with increasing incidence in the older age groups.…”

Due to recent technological improvements, namely in the field of piezoelectric sensors, ballistocardiography – an almost forgotten physiological measurement – is now being object of a renewed scientific interest.Transcending the initial purposes of its development, ballistocardiography has revealed itself to be a useful informative signal about the cardiovascular system status, since it is a non-intrusive technique which is able to assess the body’s vibrations due to its cardiac, and respiratory physiological signatures.Apart from representing the outcome of the electrical stimulus to the myocardium – which may be obtained by electrocardiography – the ballistocardiograph has additional advantages, as it can be embedded in objects of common use, such as a bed or a chair. Moreover, it enables measurements without the presence of medical staff, factor which avoids the stress caused by medical examinations and reduces the patient’s involuntary psychophysiological responses.Given these attributes, and the crescent number of systems developed in recent years, it is therefore pertinent to revise all the information available on the ballistocardiogram’s physiological interpretation, its typical waveform information, its features and distortions, as well as the state of the art in device implementations.
