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. : )

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.

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.

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.
please tell me you have acquired an extended interval qt? or from birth? have you done a genetic analysis for a mutation?

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.

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.

In our hospital’s paediatric ward. Professors were taking ECG after admistring calcium and reading QT interval. What is the reason for this?
@StrongMed4 жыл бұрын
The rapid administration of IV calcium has been reported to be associated with a variety of acute arrhythmias, but continuous ECG/telemetry monitoring is a more appropriate way to monitor for this than serial 12 lead ECGs.

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.

I'm very sorry, but I cannot give specific, individualized medical advice here. I recommend asking your personal physician about the QT interval on your EKGs.

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?
@StrongMed Жыл бұрын
The rule-of-thumb is that the QT - not the QTc - should be less than half the RR interval, and this only applies when the rate is normal. At very fast rates, it's possible for the QTc to literally exceed the RR interval without it being technically prolonged.

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?

Don't know. The limiting factors are time, and tracking down great EKG examples (which is also the delay with my almost-finished videos on WPW, SVTs, VT, atrial flutter, and hereditary proarrhythmic syndromes...)

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..
