Abstract

A 60 s time-series record of AP, RL and Z-axes data is taken from a head-mounted 3-axis accelerometer, along with a 3-lead ECG signal. The R-wave peak is then used as a trigger to conduct spike-triggered averaging of the accelerometer data. As a result, a cardiac-linked acceleration waveform appears. The latencies of these resultant waves are compared to the latencies produced when an accelerometer is placed on the chest wall.
