Abstract:	The microwave interferometer is utilized to pick up vibrations of the anterior chest wall produced by the cardiac activity. The objective of this project is to find the causes of different peaks in the output of the microwave interferometer. The output of the microwave interferometer is recorded simultaneously with EKG and jugular pressure pulses. Eighteen subjects had their mechanical vibrations of the chest wall, EKG and jugular pressure pulses recorded. The processed interferometer data, when compared with EKG and jugular pressure pulses appear to have a close relation to the mechanical events in the cardiac cycle. Four peaks in the recorded output of the interferometer are identified by this comparison. Out of 18 subjects 15 confirmed this findings. All recordings are made from healthy male subjects, at normal heart rates. Further clinical studies are recommended for confirming these findings.
