Abstract
Vibration measurements on the thorax deliver characteristic patterns in the time domain. It was demonstrated that they contain relevant information on the heart rhythm. In particular, it was possible to measure the time interval corresponding to the PR-time in the ECG. The PR-time is very important for cardiologists because its variation from normal values is associated with various cardiac diseases. In this chapter, the typical VCG signal acquired on the thorax is introduced and the reliability of the detection of the PR-time in the VCG is analyzed. A method to determine the uncertainties is shown and the uncertainty contribution due to setup features is analyzed.
