Rate and Rhythm | Normal Sinus Rhythm

Ninja Nerds,
Welcome to our Electrocardiogram (ECG) playlist! During this lecture we will begin by learning how to read and interpret a 12 lead ECG of Normal Sinus Rhythm. This video will lay down the groundwork you will need in order to read every ECG with confidence! This is an incredibly important clinical diagnostic tool that is used frequently by medical professionals most often in a hospital setting.

For anyone want to know from where he got the number 300
We know beat per second equal to frequencies, so frequencies*60 = beat perminute and we know frequencies = (1/duration) where duration is the number of large box times 0.2
So Bpm=(1/0.2*number of large box)*60
Bpm=(5/number of large boxes)*60
Bpm=300/number of large boxes

5 new videos in 1 day??!! Too good to be true, this is awesome! So happy!

Nothing better than a systemic approach to mastering EKG. And you make it more fun and tolerable with short but many videos. Thank you Ninja 🥷❤️

[hannahbergamini]

I am so grateful for this video i could cry. Thank you thank you thank you! Literally could not survive cardio in med school without your channel.

Getting ready to take my NHA EKG exam very soon. You have become my EKG teacher/book and all I had to do was plug you in my ears and you made this VERY understanding throughout the whole process. Thank you kindly for doing this wonderful/outstanding video. You are my Ninja superhero!!!!

[AlexandraAle]

This lesson is absolutely amazing! The only problem: when you say look at this R or look at this little box, it passes some time until I figure which R or which little box are you referring. So next time: can you put a big arrow or something that pops out?
Thanks a lot for all your videos. All of them are very useful. I learned a lot ❤

Super great videos! I mean really good. I have well over 25 years in medicine and took a break for 10-years. I have come back to medicine and currently in paramedic school so I can volunteer for my local rescue service. Take 10 mins and whip out your credit card (like I did!) and help these fine people continue their great public service. Simply outstanding!!

[santino]

i cant believe how much easier you've made this to understand than my uni lectures. thanks

[AtreYaas]

You are a live saver !!! A help from God !!without your videos I really don't know what I was going to do with all those nonsense material reading from my book and hearing in the class. So proud of you as a Persian Girl 😊

[joeamrine]

You're so talented at explaining material... it's a very unique experience it's just so strange how before this was so challenging to learn but you make it so straight forward it's a surreal experience...

Bro -- help! Not joking -- I can't see where you're drawing and what you're analyzing with the final checkbox: the QRS assessment and the 3 boxes at about 12:00 minute mark. Where are you drawing, what are you assessing, and where in the world am I supposed to be looking? haha, I was following everything -- even as a emt -- up until this moment. Please advise; I'd really like to keep going with this video but I'm absolutely lost. My guess is that I can pick any QRS grouping and assess it. For the sake of following your instruction, I'm trying to follow along in this section and am eager to find out where specifically you want to draw our attention toward for the final checkbox at the bottom of the Rhythm list. Thanks in advance.

gonna rock my cardiology ward with this gifted youtube channel.

[monishshivamonishshiva]

who was struggling ECG ?
but after i see this ECG. your explanation was very well sir.
very very helpful for me 🙏🏻
you are a good teacher 😊.

[sanam.soltani]

This video helped a lot. My professor only taught based on lead II and all of his sample questions lack the bipolar limb leads. I thought I would be doomed but that explanation around aVR saved my life.

[mahanoor]

Thank you for existing and saving my semesters everytime!

[Franzellcon]

The perfect definition of the word teacher is you.

[arjunjmenon]

You, sir is a gift from God !! You are an excellent teacher .

[brunadessena]

33 years in prehospital, these are outstating! thankyou

In that rhythm strip, which is regular you would count the number of large boxes between two consecutive R waves and divide by 300 and it will give you a heart rate of 75 beats per min. If the rhythm is regular, you would apply the scale, or the number of large boxes between two consecutive R waves and divide by 300. If the rhythm is irregular, you would count the number of R waves in a 6 second strip and multiply by 10. That is the understanding that I have. I love your videos, and I have learned a lot from you.

6th year med student reviewing my cardio for the emergency class, definitely ain't forgetting the method now! Thank you professor!
