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