# Heart Rate from Pressure-Time Graph. watch

1. Hi, how do you calculate the heart rate in beats per minute from a graph of pressure-time. the graph contains several curves (of aorta, left ventricle, left atrium). Could anyone give an example/the formula of how to calculate it?

Thanks
2. work out the time for one heart beat, so choose a point on the x axis, and find the time taken for that point to appear again ( so essencially one complete heart cycle). so it should be something like 0.8s.
divide this time by 60 to get HR in BPM.
e.g 0.8/60=75BMP
