摘要

从头戴式3轴加速度计以及3导联心电信号中获取60秒的AP、RL和z轴数据的时间序列记录。然后将r波峰值用作触发器，对加速度计数据进行尖峰触发的平均。结果，出现了与心脏相关的加速波形。这些合成波的潜伏期与在胸壁上放置加速度计时产生的潜伏期相比较。

Latencies of Cardiac-Linked Seismic Pulses in Head Accelerometer Measurements

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.
