Abstract: The diagnosis of a cardiac patient is dependent on the instrument used for monitoring the pulse rate and the blood pressure at
various key points in the body. Hence independent, reliable
and sensitive instrument
cannot be overlooked. The digital instruments are superior
one in this regard. The authors have developed “Digital
Phono Cardiac Monitor”, an instrument which
functions on the principle of frequency counting corresponding to analog pulse
rate and pressure. This device is capable
of detecting the maloperation of the heart-valves by counting the frequency difference in phase. Wi1h this device we can study the normal and abnormal conditions of heart and lungs as sensed and indicated by the abnormal sound wave. The most important sounds are
heart-sound, heart-murmers, respiratory rates and peristaltic squeals or groans.
Keywords: Digital Phono Cardiac Monitor, Pressure, Analog Pulse Rate.
