Thanks for such a great tutorial! I thoroughly enjoyed watching the amount of material you covered in such a short amount of time. Your use of graphics, animations, text all linked to your narration was a joy to behold. Thanks for sharing with us all.
This is so helpful! i was so tired reading books and yet can't really imagine & understand it and then there goes your video, all short and clean & it's beautifully explained, thank you!
My classmates and I in an acute care DNP program are EXTREMELY grateful for this. We all had quite a lot of ECG experience before, but absolutely none of us had any experience with the cardiac axis, as that was usually dealt with by other providers when we were RNs. This was a succinct, helpful presentation, & we've passed it around among pretty much everyone in our class. Thank you so much!
I can't express my happiness for being familiar with your MAGIC explanation about Cardiac Axis , ECG , as well as Reading Strip rhythm ... which I've suffering from them for months ... I'm really smiling form ear to ear and impressed with your greatness ! God bless you Dr.Smith 🌹🌹🙏🏻🙏🏻
Thank you, thank you! As an EP professional (but one whose job rarely requires analysis of the axis) this is a lifesaver! Now I can easily calculate the axis for each of my patients which will actually help me be better at what I do. :-)
WOW! after years of being a med student and panicking when a consultant asked me about axis deviation, i finally understand this!!! thank you SO much!!
Wow... that was very well explained. 12 leads have been the death of me however this video has given me hope of finally understanding how to calculate the axis. Thank you!
Leads I, II, and III are the limb leads. aVR, aVL, and aVF are the augmented voltage leads for the right arm and left arm and left foot. They are augmented because the sum of voltage called Wilsons point created by the limb leads I,II ,and III is to small to create a meaningful deflection on the EKG. This needs to be corrected.
Regina Becker Agree entirely with what you say but as it makes no difference to the interpretation of the axis I am going to leave it as I haven't got the time to re do the video. Sorry! N
for all the people who are willing to understand the true electric fundamentals of ECG - it is NOT the lead, it IS the + ELECTRODE towards which the el.impulse travels and hence generates the positive(upward) deflection on the ECG graphy.
@nick smith I'm sure this video isn't perfect, but I'm so grateful that you posted it. Everything else was too detailed and I didn't know where to start. This is a great starting point, so THANK YOU!!
Thanks for this, quite useful for the cardiology lab portion of my exam! It's tricky at first but it goes down to first principles interpreting the magnitudes and angles of your vectors
Hi. It´s a great educational video. I suggest that you should change the video in the 2:51 minute, because the axis is in -120 degrees, not in -150 degrees.
I’m only 14 but this stuff is really really intriguing to me. It’s always fascinated me my whole life, and I’ve been trying my best to understand the raw basics of cardiology. I’ve checked out books from the library and done research online, but this video did quite help a lot on this topic. Thank you
Excuse me for the note: when I correct the electric axis, considering the equiphasic derivative, if the QRS is mainly positive on the equiphasic I correct the axis by 15 degrees towards the positive pole of the derivative, and vice versa. Correct me if I'm wrong
2 hours of class lecture of gibberish...... into 5 minutes of UNDERSTANDABLE information. THANK YOU!
Thanks for such a great tutorial! I thoroughly enjoyed watching the amount of material you covered in such a short amount of time. Your use of graphics, animations, text all linked to your narration was a joy to behold. Thanks for sharing with us all.
A word of recommendation from the best anatomy teacher, I must never miss watching this video then...
Of a class of three ppl and a month to learn this has no comparison towards this awesome 5 minute video.
It feels illegal for this to be this simple, best explanation! thank you
you’re welcome
I’ve been trying to understand this for hours, and you just explained it perfectly in minutes.. thank you!!!
This is so helpful! i was so tired reading books and yet can't really imagine & understand it and then there goes your video, all short and clean & it's beautifully explained, thank you!
After watching your video I finally had that "ah ha" moment for understanding how to apply this concept. Thank you for sharing this!

My pleasure 😊
@@NickSmithUGME sir will you read my ecg
"Congratulations you've just worked out the cardiac axis" EUPHORIA!
Thanks a lot!
Wow! The morning of my exam I watched this video and learned this way. Very simple. Very helpful.
I could never understand the cardiac axis until this video! Thanks so much!
Honestly, the best explanation I ever had so far, I now understand it! Thank you!
You're very welcome!
First year medical student with an exam on ECG tomorrow- many thanks for this. It really helped!!
what happened to u? do u still at med school?

Thank you so much! You did it in just minutes rather than hours of reading!

OMG I HAVE NEVER SEEN SUCH A BETTER AND QUICK EXPLANATION, GOD BLESS YOU
Clear, concise, and informative. Thank you for a great video!
I have tried to make sense of this for years- thank you for your clear explanation
Thank you a lot. Ur explanation allows me to understand just like within five mins.
Clear and simple and comprehensive
Thank you sir
Wow... way better than my textbook... Thank you! :)
Thank you. The first time someone actually explained this so that I understood!
Leads I, II, and III are the limb leads. aVR, aVL, and aVF are the augmented voltage leads for the right arm and left arm and left foot. They are augmented because the sum of voltage called Wilsons point created by the limb leads I,II ,and III is to small to create a meaningful deflection on the EKG. This needs to be corrected.

I just thought where you had so many views it ought to be correct. Otherwise well done!
Regina Becker You make your point well - have added an annotation to the video and credited :)
Thanks

Wow that the answer to all my confusions in determining cardiac axis, sir hope you have a great day
First video on this topic which seems to be comprehensive for freshers too.. kudos
for all the people who are willing to understand the true electric fundamentals of ECG - it is NOT the lead, it IS the + ELECTRODE towards which the el.impulse travels and hence generates the positive(upward) deflection on the ECG graphy.
@nick smith I'm sure this video isn't perfect, but I'm so grateful that you posted it. Everything else was too detailed and I didn't know where to start. This is a great starting point, so THANK YOU!!
this the best video on cardiac axis i've seen so far.. amazing work. . thank you very much.
You freaking legend dude thank you
thank you
Omg this just helped me tremendously! I have 2 months until my state exam and this was something I could NOT grasp
Thank you so much! I finally understood ECG axis calculation after 4.5 years!
Clarity. Pure and simple. Thank you sir
I'm currently revising ECG for an optional module in nursing at King's College London and this has helped me crack axis; my biggest thanks to you sir!
That was fantastic. Thanks so much.
Insanely amazing vid!! No words can describe how beautiful this is
Love when something is summed up so well. Lightbulb moment!! thanks
SIMPLE AND TO THE POINT
This is absolutely beautiful. Thank you!
Thank you! I had a report due and had no clue where to start. Cheers
Its just an amazing explanation.. great job👍👍👍
Thank you so much! Quick and simple explanation.
This is so helpful! Thank you so much I have learned a lot through this tutorial.
Thanks for this, quite useful for the cardiology lab portion of my exam! It's tricky at first but it goes down to first principles interpreting the magnitudes and angles of your vectors
Thank you very much for the explanation. Finally, I understood how to interpret axis.
Thank you so much for such an amazing and simple to understand explanation !!!
Thank you sir! you just made cardiac axis very easy.
Hi. It´s a great educational video. I suggest that you should change the video in the 2:51 minute, because the axis is in -120 degrees, not in -150 degrees.
Yes, you are right
So helpful!! I have a cardio exam coming up!! -med student
I'm so thankful you can't even imagine
lifesaver...simple and bull's eye
thank you
The best ECG video!
Works every time. Thank you so much! Subscribed!
Thank you sooooo much i understood very well.
Nice explanation... Five star..
Superb bro !👏

This is awesome ❤
Thanks Dr. Smith! this is by far the best video on lead calculation. Why should you move 15 degrees, is this part of a calculation?
Thank you so much!!!! This was very helpful!
Thank you for explaining this so well.
great work. thank you very much.
Dude. this is crazy useful. Thank you.
This is perfect! Thank you very much indeed!🌸🌸💐💐🏵🏵
Wow!!! Amazing explanation! Thank you so much!!
YOU'RE ACTUALLY AWESOME! THANK YOU SO MUCH!
This helped a lot. Thank you very much.
Oh my God this is awesome.. Thank you.. :)
Beautifully explained!
Awesome explanation
nice explanation! I would add that considering aVR would have underscored your whole conclusion. (But I know you were thinking that :-)
Great point!
Beautifully explained
Thanks a lot!!! This is very useful.
reis thank you
Amazing explained! Thank you !!
You sound like Ramsey Bolton.
Great explenation
Thanks, v well explained
This really helped me! I have one question, what if all leads are positive of negative, so there is no equiphasic lead? Thanks!
very good basic info
Perfect video, thanx for sharing😊
Excuse me for the note:
when I correct the electric axis, considering the equiphasic derivative, if the QRS is mainly positive on the equiphasic I correct the axis by 15 degrees towards the positive pole of the derivative, and vice versa.
Correct me if I'm wrong
But when we have a vector perpendicular of the electrodes axis it's 0 means we see nothing on the ecg ? How is it possible that we have bipolar wave?
brilliant, thanks!
Where does the axis go if you are lying down vs sitting up?
Love your vids
Thanks, was really helpful.
Thank you so much!
You have a good explanation, but I do not know how to Find the value of the high R and S Nick Smith
useful AF. thank you
Nice
Awesome
thanks, that did help.
Thank you so much!!!!!!!!!!!!!!!!!!!!!
Brilliant. Thanks!
So if the wave form on Lead I is more POSITIVE than equiphasic, does tha mean that it is a LEFT axis deviation? Thank you for this video, by the way.
Thank you, thank you, thank you!!!
Thank you so much
thank you that was so helpful :))
Thanks a lot.
