Seismocardiography is a simple and non invasive
method of recording cardiac activity fro
m 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 seismocardi
ogram 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.
