摘要: A method and apparatus for measuring the heart rate of a patient. In one embodiment includes hollow bell mounted on diaphragm. transducer element is also positioned therein to receive sound transmitted through diaphragm, convert sounds into electrical impulses, transmit impulses microprocessor. The have real-time wave patterns corresponding original sounds. microprocessor performs mathematical operations pattern data conveyed by determine numerical value frequency patterns. This sent digital output displayed thereon.
