Your videos are ever so useful! Just wish you could make the pointer more visible. Sometimes it's difficult to keep track of where you are pointing 😅

[@nagarjunreddy5966]

Agree

[@grwest-jv1bs]

couldnt agree more about the pointer

[@patv9297]

god yes, i thought i was missing something

[@heatherduncan5826]

Agree

[@mandaaro1821]

agree

[@stephendurling]

These videos have first helped me to get introduced to a particular topic, and incredibly these same videos further my basic understanding into a more broad and thus useful tool to care for patients. Two Ninja thumbs up!

[@beatriceportento8633]

If anyone is wondering how he got 300 for the atrial rate for A-fib, the pointer is by V1. 7:25 - 7:33

[@aravinths77]

Thank you

[@_abdiqathar_coolmie7883]

Thank you so much. I was really struggling

[@vinayakvyas4179]

Thank you 😊

[@estherlively5170]

Honestly, I am currently in PA school right now in our Cardio module learning about EKG through ZOOM due to COVID-19, these videos are literally SAVING me from a lot of headaches because I did not understand what our professor was talking about. THANK YOU for making learning EKG fun and totally understandable. I WILL CONTINUE to donate and support your gofundme page since I will be on this page for other modules as well. It looks like these EKG videos are pretty new, and it couldn't' have come at a better time. THANK YOU SO MUCH and continue to post during these trying times. They say doctors save lives, well you save our lives or any future health care by sharing your amazing knowledge with us

[@georgepaul6240]

It's awesome to finally see this series

[@sruthik3669]

After so much of hunting finally found this ninja nerd science ... its really really useful .. ur patience ur diagrams, thank u sooo much pls don’t stop ur good work

[@thefenerbahcesk4156]

I have a final about this next week. Thanks for being there as always.

[@Heba-je1en]

Your ECG videos are the BEST, thank you 🙏🏻

[@Zetsuke4]

I learned so much this is the best way to teach this honestly

[@momolulu8910]

so far your videos...are one of the best...helping a lot students...to understand the pathophys of many subjects...

[@gcflupis]

Very clear explanations!!! Thanks a lot 🙏🏻🙏🏻🙏🏻

[@kaze123ckr]

difficult to follow where you're pointing at wish the cursor could be bigger and you can zoom in the particular place during your explaining But really thank you!!!!

[@jebakumar9717]

yes

[@SS-fd8kh]

same

[@siavasilopoulos1941]

Thank you so much for the video I’m studying for my ACSM CES exam and I need the review the last time I learned a EKG was 7 years ago. This is refreshing

[@billiegallagher8401]

You are wonderful , please keep doing this !

[@belindajoffe1857]

Can’t stop watching your videos

[@faithistheway.8258]

Loved the explanation. Thank you.

[@nathaliaschramm1592]

You could make videos analyzing X-rays. To interpret them is very difficult sometimes too.

[@Joseherreradesoares6640]

That fresh vid great quality dude keep up with the great work

[@julianaaponte3537]

Thank you so much for these videos.

[@krishsathish3076]

i love the work u guys do. U guys have helped me a lot throughout the years. just a quick favor. Could you talk more about skeletal and integuementary. Skeletal, specifically the physiology of like functions as well as ossification

[@sumaya4882]

Best explanation ever 👏🏻

[@samiraandalibizadeh3738]

You are amazing, the way you understand and explain is so fabulous. Would you please explain the physiology of fatigue and pain! Any tips will be greatly appreciated regarding those physiology. Thank you.

[@gooddoctor6434]

Best one Wallah❤🙏

[@dennypaul6119]

Great Lecture! My only comment is that when you are showing a point on the graph that is small it is sometimes difficult to see where you are.

[@donnanewkirk1204]

It would be awesome if you could project those EKG's on the whiteboard so we could follow you easier. I'm a VERY visual person and watching you draw things is SO helpful!

[@filipafalcao2403]

i already searched for so many ecg videos and these are definitely THE BEST! Thank you so much :)

[@rayana.ibrahim1344]

awesome 👏🏼 please make more videos about ecg ❤️

[@mariamhussien6303]

Keep it up guys awesome content

[@rkmusicstudio1008]

I will wait for your next lesson

[@the_true_medicine]

Thank you so much, sir.

[@manusiataat8734]

Thankyou somuch for This masterpiece video thankyou very much

[@malinallirn4395]

when you are measuring the fib rate, I don't see where you are pointing to determine rate is over 300. please help is so confusing thank you but I love your work is super awesome.

[@dorettemelville6337]

I love your teaching, this one however is hard to follow

[@Borlingr]

You're the best!

[@salmaelsenbawy6526]

AWESOME thank you ❤

[@reggiepalmer6157]

Great to know because I have been suffering with this for 20 years😖

[@ayushlal6198]

Woow best explanation

[@denised3956]

love! thank you!

[@amaaltoos4432]

So great .. thank u

[@themedicaljourneyofdiana2823]

AMMAZING!!!

[@betaabera3352]

Hi Ninja Nerd, I am from Ethiopia and Year 1 Internal Medicine resident. I keep watching your Videos they are the best in internet by far to this day from the videos I watch. please would you release videos on Hypo/Hypernatremia?

[@drarsalankhan6378]

Thank you sir

[@goncalolemos5932]

Best videos ever on the subject! Just would like to understand what cause the AF to occur?

[@AT-yj8gl]

Watch his video on arrhythmias. I think he said it's Eads or Dads. Not sure. But has to do with trigger activity

[@kinoagent007]

Great, thx!)

[@venkatesanrenuka3957]

Thank you 😊

[@shahanurmomin5084]

Thanks sir😊

[@marco_marvelous]

THANK YOU

[@musieberihune1723]

Thank you

[@SS-fd8kh]

Thanks a lot! :)

[@christyhinds3185]

Pointer wasn’t very easy to keep up with. Need to use something different. Great video’s.

[@wendibaldwin6564]

Thank you!!!!!!!

[@alper3750]

literally just in timee

[@reemalnoor3484]

thank you

[@MaroonGoone]

Dang it can be so hard to see where he is writing/pointing i.e. at 7:21

[@MarysZenDoodleArt]

thank you :-)

[@utopia2890]

Where did the Lead II strip from the top right come from? Is that a strip from the same ECG? Why is it different than the ECG recording on the left?

[@MatanLinevitz]

תודה!!

[@Tshering014]

THE POINTERSSSS! Love the video but wished I could track where you're poiting at!

[@drluqmanjeylani9655]

Thanks

[@mandaaro1821]

good video

[@celinehoward6218]

Couldn’t see the pointer some of the times. But great job explaining.

[@qamerq1911]

At 7:24 you are saying the distance between this fibulatory wave and this fibulatory wave. But nothing can be seen on the screen. Which wave are you saying.

[@morongoekhama4870]

very easy to understand video,but its also difficult to understand if you can't see what is being pointed at.

[@aslbekyuldoshev5264]

As good as possible

[@carlostellez8267]

Hi, question? Why in the Atrial flutter slide the rate between the 10sec strip and 6sec strip is so different? 150 vs 70? Thanks!!!!

[@N1Rguitar]

I think that the lead II 10sec strip is actually from a different ECG and that's why the rhythms are so different. I mean, in the left ECG there is regular rhythm while in the 10sec strip it's clearly irregular. They're definitely from different patients/recordings.

[@maryamzahid1566]

Im wondering because the lead ll measurement is 70 but that looks like a 6 sec strip not a 10 . So how did we multiply it by 10?

[@julijanikolovska2082]

It's a different ECG. When it's a 6 second strip you multiply by 10. When it's a 10 second strip you multiply by 6.

[@jorbilaine]

Can you compute the QT interval when the rhythm is atrial flutter?

[@TheAndreasBL]

Would be nice if you would sometimes speak of the treatment aswell

[@kaviyamurali5894]

Very useful 👌 make ur marker visible i find very difficult to trace that

[@user-uk8nl6px9h]

Thanks for the videos, they are amazing. But I didn't understand, you show LEFT ECG with HR 150 (after every P appears QRS complex, AV association, R-R is regular, so it means rhythm is sinus tachy) and the RIGHT ECG with AV dissociation, ventricular rhythm 70 bts/min, and atrial rhythm close to 300. So, I didn`t understand where on LEFT ECG is atrial flutter ( ok, i see sharp P-waves = F-waves, but there is AV association and HR is 150). Thanks for your answer!

[@mr34]

I have just been diagnosed with Atrial Flutter so this is really interesting. Thanks.

[@AnonymousAlien2099]

How were you diagnosed? Using an EKG?

[@mr34]

@@AnonymousAlien2099 I used an Apple watch, which has a single lead ECG function. I recorded my heart playing up during exercise. I can always see my heart rate go up on my Garmin heart monitor. I gave the recording to my cardiologist for diagnosis. I'm now booked in for an ablation.

[@W3BKY_73]

For a flutter example, is the separate lead Ii only strip from the same patient? I was confused by 1:1 in 12 lead and 3:1 on the separate strip...?

[@zas881]

thanx

[@darwainmartial9519]

very useful video...please put a bigger pointer

[@patrickp4571]

so good 😭why do i bother using other resources

[@khaoula7389]

thnx

[@srahman2610]

@Ninja Nerd, I can't see the pointer! :'( Love your videos..please solve it.

[@shaditabbarah4008]

the best

[@hudaessa9539]

awessssssssome

[@louielyn16]

Hi, thank you so much for this lecture, it helped me a lot as a new cath lab nurse! And would you be so kind to answer my questions please? :D If we go to A-fib ecg: Yes, the ventricular rate is 66 bpm, and it's not atrial rate because we are counting the R wave there. Then at the end A-fib is around 350 to 450 bpm, but in identifying the P-wave, there was none. How can we really determine if it's Afib? There should be P waves, isn't it? And what will be the correct HR of the patient we are currently assessing if he/she has AFib? Sorry for my silly questions. :D Thank you!

[@patriciabong20]

thankyouu

[@maryamzahid1566]

I have a question ??? In lead ll , theres a different strip but that looks like a 6 sec strip not a 10 .So how did we come up with 7 into 10??? I hope u respond

[@vsp3c]

12:30 I thought this would be 2:1 aflutter..?

[@Freqfitt]

It iss, i guess he made a mistake Usually a ventricular HR of 150/min is indicative of 2:1 a flutter and a ventricular HR of 300/min is indicative of a 1:1 flutter

[@Mariam-nv1fk]

thank youuuu but i have qs why there is two rates one is 150 and the other is 70 ???

[@ryanciesla6417]

looks like they are 2 different example strips count the large boxes on both you will see the rate difference in the R-R.

[@peterfitzroy4003]

are the t waves hidden in the sawtooth waves for the second example??

[@AMRsti93]

What is it when your heart beats rapidly 3 or 4 times then pauses. Then does it again then pauses. Then does it again then pauses

[@MedicalTreasure77]

Sir, how to calculate atrial flutter and fibrillation rate ? Any formula

[@MedicalTreasure77]

Sir is it possible that an ECG of atrial fibrillation the rate will be brady?

[@coachingcounselor7437]

Always love your videos but at several areas, I couldn't see where you were pointing to, so it interrupts focus

[@hitomiakuzaki4084]

I got a question, why did he say the ratio is 1:1, not like 1:3 or 3:1 in 12:50? Thanks

[@SabyasachiChatterjee82]

Can't see anything on ECG. Please do something.

[@002adityar2]

Why is lead 2 6sec rate diff from R wave *6 ( 70 and 150)

[@sethandrews1282]

Is it not a rate of around 110? 6 second strip x10 for a 60 second rate?

[@mia9397]

Can you please point out where you are by moving the pointer 😮

[@sundeepkumar3248]

Plz when u marking its not seen clear ( on ecg strip )

[@ahimakalluraya2040]

Atrial fibrillation can be seen even at 100bpm?

[@dandileander8823]

why are you not using 6 second rythm strip? how do we know when to use 6 or 10 second rythm strip? in previous video you explained bc there are 6 second rythm strip,, here's also the same,,

[@giardialambia711]

What does it mean to have 2:1 AV conduction ?

[@timspeer3750]

Means 2 p waves to every 1 R wave. On the second one, i would diagnose it as atrial flutter with Variable AV conduction ratio cause its not consistent at all in lead 2

[@indefat]

I don't get it, why is the first ECG not Atrial flutter? Atrial flutter with variable conduction? Isn't that the saw toothed pattern in V1 after the QRS?

[@dr.noir27]

7:31 where are you pointing at ?

[@thomashendron4356]

Very difficult to see your cursor on P wave , qrs, lead 2 etc . Help if larger or a different color
