What an outstanding teacher. Calm delivery. And to the point.

Maan... 46 yrs old.. Trying nursing,.. last semester, 3 months 2 go! I have my 1st exam in critical care ... Specifically respiratory and cardiac topics... I had a long day in clinical n every patient i had was literally helping me to remember my exam notes... I saw a person intubated w am ETT tube, i tried to insert an IV on him... Freaked out.. 1st time... But I'm so glad it happened.... Now I'm not afraid, I'm determined to get it right next time.... I'm not scared any more! I saw an 88 yr old, code n not make it all in one day and i didn't break down, now I'm watching this video and it all makes sense... Sorry too long but what a day! All this just to say thank you Dr. Campbell, i feel smart because of you... Like i said, u r welcome to my graduation... May 7th 2022! Bethel University Mishwaka Indiana... Ask about us... We are regionally respected... But thank you from the bottom of my heart!! Please flag this comment with a graduation cap and love 🎓 💕 Cap💕 until he sees it .... 3 months darlings ... He helped me a lot!!!

Currently on my cardiology rotation and the stress is getting to me. Thank you so much for making this easier to understand.

Thank you soooo much for this! 😁 Now THIS is EXACTLY what I was looking for! I work in the Cardiac Catheterisation Laboratory and we need to understand and visualise the quick changes that can happen on an ECG during a patient case. You are amazing! Such invaluable information that shows a live ECG! Showing exactly how normal sinus rhythm can deteriorate into a cardiac arrest, shockable rhythms ventricular tachycardia and ventricular fibrillation which can lead to asystole. I loved that you included extra information and simple explanations about Pulseless Electrical Activity (PEA) and Hs & Ts. Dr. John Campbell, you sir are simply incredible! Now I feel more prepared to recognise these sudden changes on an ECG and tackle these difficult situations. You have taught me so much in less than 10 minutes! Thank you again and keep up the great work! 😁

Thanks; I've watched quite a few of your videos so far. I am an ODP and I have my ILS course on Friday - watching your videos is definitely helping me to get my head around the cardiac arrest rhythms and the reversible causes!

Thank You Sir. Very well Narrated . From an Anesthesiologist in Cairo, Egypt (Middle east-Africa).

Such a great lesson. Final semester nursing student here! PS the accent just makes it even more amazing

Subscribed. Such a great teacher very inspiring thank you

Oh these are hidden gems, thanks Doc.

Great video, short and to the point ! Thank you so much

My 15 year old daughter went into SCA, I remember reading VF, Asystole and PEA on her EMT report. Tried to learn what it all helped but still have a hard time. This video helped a little. Even after having an autopsy and many EKGs before she died there was never any reason found for her to go into SCA and die :(

Thanks, this made a lot of sense. About to do my ALS as a RN

0:01 QRS 0:17 VF 4:07 VT 5:25 asystole 6:15 PEA 0:01 QRS 0:17 VF 4:07 VT 5:25 asystole 6:15 PEA

I really love the way you teach us thank you so much as a nurse i have many more doubts but when ever i see your videos it give me very much ideas to comprehend my knowledge

Thank you Dr Campbell !

Another super helpful video, thanks Doc.

In the last few years, I have stop renewing my ACLS because it was not a mandatory certification. But, now I'm getting ready to take ACLS again, and will ask for reorientation in my specialized area. I was very surprised and delighted to see Dr. Campbell's informative and extremely helpful videos (prior to this I've see only Covid-19/pandemic videos, helpful, unbiased). Thank you Dr. Campbell for your love (one aspect of love is to share knowledge), and true compassion (the caring of others, especially with us strangers).

Thanks for this.. Great help towards my EMT exams.

Amazingly easy to understand! Fair play.

wow thank you very much for making things easier to understand and remember

I had an atrial flutter that made me pass out. Thought I was going to die :( Doing ok now :)

This was super helpful, I've been struggling to understand these for some time! Thank you very much :D

Just went SVT was awake and could not be sedated, just don't respond to narcotic medications intensely. 148 joules later and awake for whole deal, still alive and home.. was a mess for a minute. 8 hours after having defibrillator removed because of infection. Made some videos myself. Much love... FFTARTAGLIA always praying strong fire in your heart, belly and soul 🙏💪🔥❤

Strangely relaxing.

Really good explanations, thank you!

This was so helpful! Thank you so much. I have a test in RN school over this and your video was so helpful!

Dear Dr John, i used to wach your lectures as medical student and it was quite helpful. Now, as senior clinician i am starting my own lectures based on recent evidences. Can you pls buy time and review mine and put your supplements. Thanks

Very lucid presentation 👏

Thank you for this video

Cardivert a VT with a pulse if symptomatic such as dropping blood pressure and unresponsiveness. In addition, administer Amiodarone 150 mg over 10 minutes followed by an infusion of the same. Lidocaine is an alternative anti arrhythmic. Defibrillate VT without a pulse. Administer two vasopressors such as Epinephrine q 3-5 minutes and Amiodarone 300 mg IV Push after the second defibrillation.

THANKS FOR THIS GREAT TEACHING. IT GAVE ME SOME IDEA

Sir, please teach us daily.

You are awesome! Thanks

I like your teaching very much,in fact we indian doctors are over burdened still wach you in between work,thanks

Good instructor!

So has he just killed the patient having failed to try to reverse the VT then the coarse VF and having let it progress into fine VF and possibly Asystole for the sake of the video?

1:30 "it''l become finer over time" --it's called death

I feel like everyone watching this are doctors except me like if you are a normal person

Extremely interesting. Thank you.

I survived an episode of V-Tac. I was the unfortunate one that remained conscious the entire time. The EMT hit me with 200 Jules then 360 Jules on the defibrillator WHILE I WAS AWAKE! I hope nobody ever has to go through what I did. Please knock them out first!

Amazing video

U are the best sir

In Germany we call v fib Kammer flimmern which means Chamber(of the heart) quiver

How do you treat PEA on monitor, hypotension, lactate acidosis and refractory arrest.

This is intersting for a person who has VF and an ICD

Thank you

I get VT everyday have a defibrillator and pacemaker inside me I an feel the VT come on but luckily for me they aren't bad enough to be shocked yet I've herd that hurts like buggery

This is amazing . So useful for nursing and nursing school

Hi, very nice described, and very clarifying! I just have one question, hopefully you can help me with this If I understand correctly; SCD can present in 4 ways on a ECG (VF, VT, Asystole and PEA, whereas VF is the most common)? And if SCD presents as VF or VT on the ECG, a defibrillator could get the patient back in rhythm? If a patient would have asystole SCD a defibrillator would not work? Is this correct? Thank you for the vid!

you mentioned the finer VF is harder to treat. Why is that?

The patient is having a heart attack and yet he does nothing! Just kidding :D

So if it were to be a prolonged section of tiny, irregular waves, it would be cardiac arrest as opposed to afib?

Hello doctor. I want to ask you one dose hypoxia cause bradycardia or tachycardia? How chemoreceptors work with it ? Thanks 🙏

Hello Dr Campbell, still an avid fan of your uploads. Was wondering do you have a video explaining the pathophysiology of the 5 h's and 4 t's. Thanks.

Love ❤️ from INDIA

"because we're not treating it, it will become a finer ventricular fibrillation" Huh, I wonder why? 🤷🤣

love from india sir🥰😊

I have a defibulator installed, 6 Feb 2020 I feel a irregular heartbeat, no pressure or pain on chest, no shortness of breath, just a little uncomfortable on chest , suddenly my defibulator start shocking me , it shocked me 3 times in almost 15 second period, I was completely awake and was standing on ground without holding anything, after 3rd shock my chest discomfort was gone and I was feeling ok,. Since then I never feel normal on my chest area, always have some discomfort, feels like someone hold my heart in hand, doctors say everything is normal, but I have a continuous discomfort on my heart , again no shortness of breath, no severe pain, but take beta blocker and thinner

What does it mean when thw monitor starts trasing down

IF someone experience this its good to know

allah bless u doctor ..ihave question why your video is high viwes its cool prognosis

Thanq sir.

is it true that is a patient is flatlining the only thing you can do is push epinephrine and start chest compressions and attempt to get them up to v-fib or v-tach and then you can use the defibrillator? idk i just heard that somewhere and it just stuck with me for some reason in not a doctor or anything lol

Had too see what a VF arrest looked like,. 2.5 months ago I had a scad VF arrest, 2 min CPR and 1 shock. Completely healed now ❤️

VT: CPR 30 pumps, 2 breaths, Amiodarone, Defibrillate, Adrenaline VF: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Asystole: CPR 30 pumps, 2 breaths, atropine, adrenaline, repeat until large wave fibrillation, then defibrillate If you're asking, I came from Reanimation Inc.

Great😊

Why does lactic acidosis cause PEA from a physiological perspective?

Can all of these be corrected with cardio version? Seems like the cure-all procedure with arrhythmia.

I think I've seen PEA also called EMD, Electromechanical dissociation.

Recently I acquired idyopathic NSVT, several dozen episodes per 24h, the longest run was 18 beats. I am relatovely Young (35 years) and have structurally normal heart. Its probably caused by hormonal fluctuations. (sex hormons, not adrenal, pheochromocytoma was ruled out). Is it dangerous?

well how can u induce a shockable rhythm in asystole? thx

What does it mean if your diastolic blood pressure is in the thirties and forties like 34 and 49?

one time my moms ekg was shown as her heart stopped and it scared the hell out of me but then the doctor just said i unplugged it 😭 why she gotta scare me like that

Would you shock all VT or just pulseless VT?

Could this also happen because the leads are improperly placed?

V-Tach Is A Fast HR 175-230 BPM Am I Right

hi there initial slide Ventricular is spelt incorrectly!!!

Me four years ago and two years ago ok

wow

Why no mention of Hypoglycemia as one of the reversible H's?

The theme song sounds like Circles by Post Malone

how would you induce a shockable rhythm for example in asystole?

I had a cardiac arrest during the intimate battering.

I have no idea why I'm here, I have never been interested in this stuff, I'm currently in a hospital scaring myself with these videos

Can a PEA actually have such a perfect pQRS complex?

i thought you cant shock asystole?

Dont eat at 5 guys

Hi. I am currently working on a project on detecting and classifying cardiac arrhythmia. However I have a few questions. Can someone please assist me with those.

I had torsades once

We shock all the v.tachs?

5:31 Asystole

I learned that the AF (Atrial fibrilation) is also a shockable rhythm as they tend to change into a Flutter, VF or VT. To avoid the severeness of that condition you should shock as soon as possible.

PCP student here!

Im a kid, yet im watching to be able to detect when to use an AED if its not able to tell.

@4:41 VT

The fact that the human heart is so good at it’s job, that if it slightly messes up you can very quickly die

6:15 PEA

i have sinus tachycardia
