Abstract
In this paper, a non-invasive technique has been proposed for the acquisition of jugular venous pulse (JVP) waveform using an accelerometer sensor. Waveform is obtained from the vibrations measured using the accelerometer sensor. The vibration signals present in the jugular vein regions are due to pressure created during the hemodynamic event of cardiac cycle. This pressure created during the cardiac cycle is measured using the sensor and is further processed. Finally, the JVP pattern is obtained by applying a suitable computation method. The JVP wave is obtained along with electrocardiogram (ECG) signal which is measured with the help of ECG electrodes. These collected signals from accelerometer sensor and electrodes are made to run in real time with the help of a DAQ system and a computer. The obtained pattern is compared with the electrocardiogram, and changes in JVP waveform’s amplitude are correlated with heart activity during cardiac cycle.
