One of the best explanations of QT interval and long QT syndrome I ever heard. Thank you .

Thank you Dr Eric Strong. I literally learn this thing for you. I owe a debt of gratitude that you teach the public. Many of medications in my specialty known to cause prolong QT but that is it. Now i get where to look , anyhow i remember from one of your lecture that if the machine read normal EKG then it is most likely to be normal. : )

finally a day came when I have learnt ECG and you are the reason very useful series thanks a ton

Thank you very much Dr Strong. It is a wonderful lecture. You tell me what is important, what is not. This lecture is relevant to my work, therefore thanks very much.

Simply amazing! Great work!!!!!

Thank you Doctor Strong. These are wonderful series. I just re watch it because I forgot everything already EKG just seem strange to me as if embarrassingly to say like I just a layman. :). Your lectures are so wonderful unrivaled.

Great video.. very clear explanation and slides are well organised.. very helpful to clear several unclear areas I had on QTc calculations. Thanks very much 👍👍👍

very comprehensive and practical....add a series of practical scenario from hospital for long QT INTERVAL

Thank you very much, for this great explanation and comprehensiveness.

Very comprehensive. Well presented.

Excellent presentation.

Excellent presentation Thank you so much

This is a wonderful video.

so touching for an excellent video

Thank you ! It’s a very helpful video.

very nice video! thank you!

very helpfull doc...thanks a lot from indonesia

Thanks a lot. Its fantastic

Thank you very much

Very helpful. Thank you.

Very helpful..thank you so much

Really helpful video. thanks Also, do you know if there is a correlation between LQTS and bradycardia? I read that somewhere on the internet but I don't know I should state that as a fact or not.

Thanks for the great video series. I was unable to calculate QTc in first example by bazette's formula. since it is not applicable for heart rates below 60 and above 120. Framingham's formula gave the correct answer. it would have been better if u had explained these other formulas also.

very helpful, thank u

you r fantastic

thank you soooooo much!!

Many thanks.

AWESOME.Thank u...Please upload video on differential diagnosis of fever,giddiness/vertigo,acute gastroenteritis because half of the cases in ER come with these complaints.Would really appreciate it.

Great many thanks

I was diagnosed with Long QT interval but was discovered in my later years 51 yrs old when I had a cardiac arrest luckily It happened when I was admitted in the hospital already. With that I had undergone pacemaker procedure it's been 5 yrs already, and also I am taking propranolol.

nice video! thx

six years ago i had an ekg that showed i have a long QT interval. I've had awful palpitations and pain in my arm n jaw and lost consciousness. they began to treat me with coro nitrate tongue spray and aspirin for a year or so (which actually made my symptoms worse) then did nothing and have done nothing since. my palpitations are SO mich worse and i sometimes feel like my heart is going to littlerally exlode out of my chest. it feels like a huge metal winged butterfly flapping about in there. my neck feels like im being strangled and yhe pressure builds up in my head all at the same time. ridiculous hospitals here in the UK cant understand what is wtong so they just DON'T HRLP. it really is outrageous. im a 36 year old female. amytriptaline literally made me collapse and my heart do some VERY scary things. i felt the whole time taking it like someone was holding something tight around my neck. such pressure and pain. amytriptaline wasnt the only drug that's done this but this was by far the worst.

Easy to understand. Difficult topic made simple

U nailed it❣️

Hi! I have a question Why does hypocalcemia causes the prolonging of the ST segment? ST is related to the plateau phase in the action potential, which is mostly related to Calcium, but why does a lower concentration of Calcium causes this phase to prolong?

Firstly thank you so much sir, amazing video, but can you tell me why hypercalemia causes short qt?

Nice work....تم التحميل

Just found out I have Long QT Syndrome. Yet my Dr. Did not refer me to a Cardiologist. My history is Blood Clots and Pulmonary embolism. So now on my own. I'm trying to see if I need to see a Cardiologist because I wasn't referred to see one. If anyone has any good advice to help me please respond. Thank you. In the meantime I will continue to watch the video.

hello, what is your lead-in music please?

In our hospital’s paediatric ward. Professors were taking ECG after admistring calcium and reading QT interval. What is the reason for this?

Where about did you find the risk score assessment tool to identify risk factors for TdP??? What literature or reference??

All my past ekgs have been perfect, but the last two I had showed qtc intervals at 468ms and a week later 478ms. Yet the ER doctor nor my Primary Care Physician either one seemed worried. Matter of fact I asked specifically about the ekgs and the ER doctor said everything was great and my PCP said she was not concerned at all. All the other findings in the ekg was perfect and all blood tests, etc... Came back perfect. So what gives? Should I worry or not since the doctors aren't concerned? I have no known family history of LQTS, I've never fainted, or anything like that.

thanksfor tye video..want to mention that ssri's dont cause qt prolongation

I have pro long Qt

QTc also should be less than half of RR interval? There is one example QTc =512 which is < half of RR interval but is still prolonged?

Is a really great video but I really wish I could understand some of the math involved

When is your EKG book going to be published!

11:34 Long QT syndrome

My ECG reads QT/QTc as 341/404ms Is this normal?

Short QT

phase 1 is due to influx of sodium which causes reversal of polarization...when it reaches to +32mv,pottasium leak channels open and causes this value to be at +28,followed by calcium influx which maintain plateau, phase 1 is not not due to outflux of pottasium...although immediately after depolarization voltage gated pottasium channels begins to open but those are not responsible for plateau..
