I’m doing this for almost 20 years. To me the easiest way to calculate in regular rhythm is counting the boxes between QRSs in 6 seconds strip then divided by 300. The irregular rhythms easy just count the QRSs in 6 seconds strip and multiply by 10. Good luck 👍
Coz 50mm/s paper speed is the same as 25mm/.5s paper speed. If at this speed there is only 25mm between any 2 R waves, it means that R waves are being produced every 1/2 second which mean 2R waves/s or 120bpm
If they are in between just take as .5 by example 300/6.5 =46 That is the heart rate. Remember you are dividing by 300 the number of boxes in between regular QRSs
Tshepiso Maduwana precise is used for sinus (regular) rhythms while the 6 second is used for irregular rhythms because if the rhythm is irregular the distance between the QRS complexes will vary therefore you can’t count the small or big boxes in between as it will be different each time

I will have to sit and this video a couple of times. It seems that I can learn more from this video than from the modules at school. Thanks
Thank you so much for clearly explaining the rate calculation for 50 mm/s speed!
I’m more confused than I was
Same 😭
It thought I was the only one 😐
🤣😩💀
I am giving up 😢😢
😂
2:53 why is the heart rate different for 25mm/s and 50mm/s speed?

What if the r waves in between large boxes. Then how to calculate it?

I wanna cry I am so confused. Where are we getting the sequential numbers? What does this represent?
Why am i watching this? I dont even have a job
tooo good..well explained👍🏻👌
The marker method helped me loads
Please explain the difference between precise rate and quick estimated rate

@@taniyahperkins7902 THANKS ❤❤❤
Thank you so much..It's very useful
How did you get 1500?
There are 1500 small boxes in 1 minute on an ekg. Same with the 300 large boxes = I minute on ekg
Very clear and useful.👏😍
I love this video....thank u so much
thank you for the video it is very helpful
may you please answer me what is the difference between heart rate and heart rate variability in ECG? please help!

nicely explained
Thank you very helpful
thank you
Thank you so much
Thumbs up👍🏻
Thank you ❤️
omg, finally i get it
Good
I also
bad video how to use the 300 method when its not all lined up properly on the line like that
Just go to the next corresponding location. So if it's 2 small boxes in, use that as the spot to start counting (in 5 box intervals).
is there a formula for this graph?
Hi stranger. Just wanted to let you know that Jesus loves you and so do I
Very hard method
