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.
