在一些生理实验中,记录实验动物的心率变化是必不可少的,而许多生理实验室并不具备专门记录心率的多导记录仪。我们研制了一种记录心率的装置一平均心率计。该心率计可与任意型号的双笔记录仪配合实现对动物心率的实时直方图描记,与传统的心电图机记录的方法相比较,它直观、省纸、投资少。如果实验要求血压和心率同时记录,上述优点尤其突出。 心率计数一般有两种方式,即平均心率计数和瞬
In some physiological experiments, recording heart rate changes in laboratory animals is essential, and many physiology laboratories do not have a heart rate recording multi-purpose recorder. We developed a device for recording heart rate-an average heart rate meter. The heart rate meter can be used with any type of dual pen recorder to realize real-time histogram of animal’s heart rate. Compared with the traditional method of electrocardiogram recording, the heart rate meter is intuitive, saves paper and low investment. This is particularly true if the experiment requires that both blood pressure and heart rate be recorded at the same time. There are generally two ways to count heart rate, that is, the average heart rate count and instantaneous
