    How do you calculate the heart rate, when you have been given the volume of blood in a mans RV at different times during on cardiac cycle????

    Ok, so the right ventricle pumps blood to the lungs. This is part of 1 heartbeat.

    Whenever the RV fills with blood, you know that it's about to pump blood to the lungs, and you can count it as a 'marker' for the heartbeat.

    So, count the number of times that the volume in the RV peaks, and divide it by the time that has elapsed. This will give you some sort of heart rate (like beats per 15 seconds or something), but you can simplify it to be per minute or per second!

    Hope this helps!!
