Epicardial Acceleration Signal Measured Using a Single Chip 3-axis Accelerometer

This study was part of a major effort to study epicardial acceleration as a mean to monitor myocardial function. This article presents new epicardial acceleration data measured with a commercially available capacitive 3-axis accelerometer. The single chip accelerometer was packaged in medical grade silicon and approved for use in clinical trials. The sensor was used to measure heart motion in an animal model. The acceleration signal was integrated to velocity and position using numerical integration. The new recordings of epicardial acceleration showed good details.
