How to Determine Heart Rate
The calculation of the heart rate of an electrocardiogram (EKG) is of great diagnostic importance, because determining a tachycardia or bradycardia may make us suspect certain pathologies and their severity.
The easiest way to calculate the heart rate is… to look for the value given by automated analysis of most electrocardiograms.
Are we kidding?
No, many times this heart rate value is an actual one and speeds up the diagnostic process.
Anyway, every professional must know the different methods to calculate the heart rate, because not always the automatic analysis is real or there are electrocardiogram equipment that do not provide the value of the heart rate.
300, the Heart Rate Magic Number
On a normal electrocardiogram, there are five large squares per second and 300 per minute.
Knowing this, we can calculate the heart rate measuring the R-R interval, providing the rhythm is regular.
Heart rate: 4 large square = 75 bpm
On the EKG, locate a R wave that matches a thick line, count the number of large squares to the next R
