Precision in your calculations is a personal preference and a matter of what is necessary for what you are doing. I'd say rounding to a whole number at the end for heart rate in beats per minute is typically going to be reasonable.
@@VivoPhys I usually work in the thousand whole number for RR interval using (6000/heart rate)*10. So yes, I'll round up to 1112 if for example the calculation was 1111.7. Thanks! Just wanted to double check.
Helllo, whats the differnece between regular rhythem vs sinus rhythem? if rr is constant then it means its regular, so how does it different from sinus rythm >??
Thank you, can a PP interval be 0 ms in an EKG? Or can that be that it wasn’t measure? Everything else has an answer in the EKG reading, except the PP 0 ms.
How does this work with HRV(heart rate variability)? In this video you only calculated her r-r and heart rate between only 2 R's, how would you calculate and determine the officers overall/entire R-R and heart rate when calculating all the distances between R's? I hope my question is making sense lol. Awesome video overall!
You would need to do the RR interval for every heart beat for a period of time. Please type my name and heart rate variability into TH-cam to find my heart rate variability videos.
Reading Dr Bernstein book on diabetes and and see it videos mention R-R interval study to ck on vagus nerve function d if gastoporesis (ck after meal BG also) by checking heart rate when breathing in(faster HR) and breathing out (slower) .
Hi Safwan Albqoor. An RR interval is the time between R waves on two different heart beats. So it is the time between two heart beats. 600ms between beats is equivalent to a heart rate of 100 BPM. Typical resting heart rates are 60-100 BPM.
I was puzzled with this calculation for an upcoming midterm exam, thank you so much for this thorough explanation ❤❤❤❤
Good luck on the exam!
Thank you so much!!!
- a first year medstudent :)
You are welcome.
Thank you! I’m in a CV nursing program and the textbook is so poorly worded. This helped me understand better (:
I'm glad it helped. Good luck.
Why do you divide 60 with 0.7 to get 85.7 BPM? - i.e where does this 60 come from?
It's for 60s in a minute.
Thank you!!
You are welcome.
Hi, would you round the rr interval up if the result was 85.78....? Instead of what it was, 85.714..., to make the rounded result 85.71.

Hello if there's 13 small boxes answer is 0.52 do I divide 60 by 0.52 or 0.5?
Hi @EyadAyman-th9ut. Each horizontal small box is 0.04s. So, 13 x 0.04 = 0.52s. 60s / 0.52s = 115.4 BPM.
@VivoPhys thank you by any chance do you know best formula to calculate QTC for high heart rates (sinus tachycardia) like 115 bpm
I believe this is a measured variable, not a calculated variable, but I've never used it before.
Helllo, whats the differnece between regular rhythem vs sinus rhythem? if rr is constant then it means its regular, so how does it different from sinus rythm >??
Sinus rhythm just means the electrical impulse originated in the sinoatrial node. This is the typical site of origination.

It's hard to say with this information, but I would guess it wasn't measured unless the person has a-fib.

@@VivoPhys will do! thank you!!!1
The video sound is pretty good, beyond my imagination
Hi Dieu Linh. I'm glad to hear it.
Reading Dr Bernstein book on diabetes and and see it videos mention R-R interval study to ck on vagus nerve function d if gastoporesis (ck after meal BG also) by checking heart rate when breathing in(faster HR) and breathing out (slower) .
how did you get 17.5?
That is the number of small horizontal boxes between R waves in the example ECG. You just manually count them.
In my holter report RR interval 1.4 second is any thing serious??
Please consult your clinician.
Thanks alot,
What we mean RR less than 600 ms ?
Hi Safwan Albqoor. An RR interval is the time between R waves on two different heart beats. So it is the time between two heart beats. 600ms between beats is equivalent to a heart rate of 100 BPM. Typical resting heart rates are 60-100 BPM.
Thanks alot
Easier to divide 1500 /17.5 to get the HR
It certainly is faster. Perhaps at some point I'll do an abbreviated video using this formula.
بسم الله ولا قوة إلا بالله
Instead just divide it 300/17.5
300/17.5=17.14 ??
You can divide 1500 by width of the r-r interval in mm for an alternative calculation. 1500/17.5=85.71 beats per minute.
