A system based on Seismocardiography to monitor the heart sound signal for the long-term using an accelerometer, which is of small size and low weight and, thus, convenient to wear and its performance is compared to the performance of the Phoncardiography (PCG) system.Abstract:
This paper presents a system based on Seismocardiography (SCG) to monitor the heart sound signal for the long-term. It uses an accelerometer, which is of small size and low weight and, thus, convenient to wear. Such a system should also be robust to various noises which occur in real life scenarios. Therefore, a detailed analysis is provided of the proposed system and its performance is compared to the performance of the Phoncardiography (PCG) system. For this purpose, both signals of five subjects were simultaneously recorded in clinical and different real life noisy scenarios. For the quantitative analysis, the detection rate of fundamental heart sound components, S1 and S2, is obtained. Furthermore, a quality index based on the energy of fundamental components is also proposed and obtained for the same. Results show that both the techniques are able to acquire the S1 and S2, in clinical set-up. However, in real life scenarios, we observed many favourable features in the proposed system as compared to PCG, for its use for long-term monitoring.read more

A Unified Framework for Quality Indexing and Classification of Seismocardiogram Signals
TL;DR: A unified method of quality indexing and classification that uses multi-subject-based methods to overcome the challenge of signal quality assurance with SCG, and is able to stratify SCG signals on held-out subjects based on their level of motion-artifact corruption.

A Novel Broadband Forcecardiography Sensor for Simultaneous Monitoring of Respiration, Infrasonic Cardiac Vibrations and Heart Sounds
TL;DR: In this article, a new piezoelectric sensor was proposed to record all heart vibrations simultaneously, as well as a respiration signal, which can be compared to the FSR-based one to assess its suitability for forcecardiography.

Smartphone accelerometers for the detection of heart rate
TL;DR: The smartphone can be considered a powerful device able to accurately measure the resting heart rate, thanks to embedded accelerometer technology, however, lack of a shared standard in the acquisition protocol and analysis procedure, thus affecting user-collected data reliability, could limit clinical acceptability and prevent recommending this approach as a self-tracking tool in patients.

TL;DR: Moderate or severe valvular heart diseases are notably common in this population and increase with age and in the community, women are less often diagnosed than are men, which could indicate an important imbalance in view of the associated lower survival.

Mortality from ischaemic heart disease by country, region, and age: Statistics from World Health Organisation and United Nations
TL;DR: The global burden of IHD deaths has shifted to low-and-middle income countries as lifestyles approach those of high income countries, and the progressive decline in age-standardised IHD mortality in high-income countries shows that increasing I HD mortality is not inevitable.
