Seismocardiography is a simple and non invasive method of recording cardiac activity from the movements of the body caused by heart pumping. In this preliminary study we use a smartphone to record this acceleration and estimate the heart rate. We compare the heart rate variability parameters from the seismocardiogram and ECG reference signal. The results show a great similarity and are strongly influenced by the instability in the sampling frequency of the device. The differences between RR series are lower than 10 ms.
地震心动图是一种通过记录心脏泵血引起的身体运动来记录心脏活动的简单且无创的方法。在这项初步研究中，我们使用智能手机记录这种加速度并估计心率。我们比较了地震心动图和心电图参考信号的心率变异性参数。结果显示出很大的相似性，并且受到设备采样频率不稳定性的强烈影响。RR 序列之间的差异小于 10 毫秒。
