A beat-to-beat cardiotachometer counting from 27 to 199 beats per minute has been constructed using digital integrated circuits. Power consumption is reduced, and accuracy enhanced, by incorporating a programmed read-only memory. This circuit technique can be employed for other devices, such as digital thermometers, in order to circumvent a nonlinear relationship between voltage and the physiological variable.
一种逐搏心率计已采用数字集成电路制成，其计数范围为每分钟27至199次心跳。通过采用编程只读存储器，降低了功耗并提高了准确性。这种电路技术可用于其他设备，如数字温度计，以规避电压与生理变量之间的非线性关系。
