seismocardiography
/ˌsaɪzmoʊˌkɑːrdiˈɒɡrəfi/
Definition
A non-invasive medical diagnostic technique that measures the mechanical vibrations of the chest wall caused by the beating heart using sensitive accelerometer-based sensors.
Etymology
The word is formed from the Greek 'seismos' (shaking or earthquake), 'kardia' (heart), and 'graphein' (to write or record). It was coined to describe the recording of vibrations similar to how a seismograph records the tremors of the Earth.
In the news
In the article, seismocardiography is discussed as a method for monitoring the cardiovascular health of astronauts in microgravity environments using wearable sensors. It is highlighted specifically for its need for advanced processing frameworks to filter out noise and motion artifacts.
