"Atrial Fibrillation (AF) is the most popular arrhythmia and diagnosed by the finding of an irregularly irregular ventricular rhythm without discrete P waves. AF is a supraventricular tachycardia. In AF the atria do not contract in a synchronous rhythm, instead they quiver or fibrillate. This means that they beat very rapidly and irregularly. The most concerning thing about atrial fibrillation is clot formation and embolism due to stasis in the atrium. The left atrium is commonly involved in clot formation resulting in embolisation to the brain causing a stroke."

love you
Thank you so much!
It is mandatory to address the cause of atrial fibrillation prior to rate/rhythm control. Like Treat Anxiety, Pain, Anemia, Electrolytes like K/Mg, Respiratory problem, Infection etc.
you explain better than the sum of who are called ''professors'' at my university. I wish we had someone like you. thank you so much.
Agreed 👏

Agree
I feel this is one of the most lucid videos on AF, not missing or messing a single event. Really an wonderful study. Thanks
I am a resident and still watching your videos. You were my hero through med school and still are
Never seen anybody explaining such a difficult topic so beautifully.

I have been diagnosed with Paroxsysmal Afib and am scheduled for an ablation in 3 weeks. I have been overdosing on UA-cam videos regarding Afib since I was diagnosed and I wanted to tell you that your explanation was the best of any I have viewed. Thank you for helping me better understand Afib!
Your videos and illustrations have come so far since the beginning!!! Love and respect your channel and your hustle!
I've taken ACLS since the late 70's and this is the best explanation (and I've seen some pretty good ones) of the subject. Anyone contemplating taking ACLS would do well to study this presentation as it serves well as a foundation for a lot of other cardiac interventions.
who's a life saver ? YOU'RE A LIFE SAVER ! :')
Thank you so much .
Please keep uploading new videos
Amazing illustration with detailed information. It was really helpful! Thank you for making the complicated UNCOMPLICATED! :)
We're just about to take a big exam on cardiac tomorrow morning !! So glad I remembered your page!
Outstanding presentation as you have explained AF in a three dimensional way, from anatomical, electro- psychological and therapeutic management within an excellent visual schematic presentation - thank you for the excellent and succinct presentation, well done.
I love your videos! I have been a healthcare professional for over 10 years & like to refresh my knowledge & skills. Most people are visual learners & I find these videos to be great & helpful for all learners.
this is the best video so far on understanding the different types of A-FIB and its treatments!!! Very detailed and informative! keep up the good work!
I am 21and have A FIB & a pacemaker since I was 16... thank you for this video.
I'm the same age as you. I'm doing a PP presentation for Human Anatomy class. Can you give me some daily tips or insight that people may not know. A-fib seems to be prevalent on my mother's side.

Unfortunate to see another person my age with the same condition as me :(
Amazing to see your progress Armando
Thank you Sir!I always found this particular topic difficult to understand whenever I tried reading from books but after watching this,I understood everything clearly.
It is mandatory to address the cause of atrial fibrillation prior to rate/rhythm control. Like Treat Anxiety, Pain, Anemia, Electrolytes like K/Mg, Respiratory problem, Infection etc.
I am currently studying Atrial Fibrillation, this video just came at the right time. Thank you for making it more easy. 😍💪🏾

Dude u have no idea how much i love u, literally I'm advertising in our faculty for u whenever i pass an exam, mwah 😘
thank you so much for your effort, you explain it in such a smooth way for such complicated topic i appreciate that
outstanding review sir. You are one of a kind. thank you so much
Thank You So Much
Your video is very informative and easy to understand while still going in depth💯
Great explanation specially the clinical parts, thanks.
thank you very much. your lecture is very much informative and easy to understand ❤️
Thank you sir ! Its really a best explanation of Atrial Fibrillation .
got everything i needed to know except dose, still great job, thank you.
Such an excellent, helpful, well-done video!! Thank you!!!
Best explanation I've see - and I've seen a few!
Thank you so much for making it so easy to understand!!💜
Incredibly well done video, thank you!
Best AF presentation ever!!!!
Woah, thank you so much. This helped a lot in my class presentation.
Cool video with great explanation! I wish i could do a video like yours
Overview
------------------
Atrial fibrillation (A-fib) is an irregular and often very rapid heart rhythm (arrhythmia) that can lead to blood clots in the heart. A-fib increases the risk of stroke, heart failure and other heart-related complications.
During atrial fibrillation, the heart's upper chambers (the atria) beat chaotically and irregularly - out of sync with the lower chambers (the ventricles) of the heart. For many people, A-fib may have no symptoms. However, A-fib may cause a fast, pounding heartbeat (palpitations), shortness of breath or weakness.
Episodes of atrial fibrillation may come and go, or they may be persistent. Although A-fib itself usually isn't life-threatening, it's a serious medical condition that requires proper treatment to prevent stroke.
Treatment for atrial fibrillation may include medications, therapy to reset the heart rhythm and catheter procedures to block faulty heart signals.
A person with atrial fibrillation may also have a related heart rhythm problem called atrial flutter. Although atrial flutter is a different arrhythmia, the treatment is quite similar to atrial fibrillation.
Very very impressive explaination. Thank you very much.
Thanks for the very clear explanation
worths every single minute! thank u
Atrial fibrillation is made too easy via this video .Thank u 👍👏
please make vedios on all arrythmias ,it would be really helpful
Awesome stuff man!!
This should be useful to an essay I may be doing so thanks so much
Thank you so much for posting this 😘🥰
Always look for other causes of instability among patients with AF and shock or difficulty controlling the ventricular rate.
Very well done!
very nice video.. thank you
Great video! Thank you!! Do you have any videos on AV blocks?
Such a nice voice and a great presentation. The presenter's name looks Latin of some sort, but I really think he sounds like Christoph Waltz
Armando went digital!! Wow.
that's super interesting thank you guys
well done explaining
Amazing, thank you so much 💜
Wowwwwwwwwwww.....thank you so much for this presentation ❤️🥺
Thank you ...very helpful
Hi, I would like to know the specific resource used in this video. I would like to read more about arrhythmias since I still can't organize these stuff in my head. Thank you in advance.
Clear explanation
Awesome... so admirable
as always great
Jazak Allah. Allah apko ajar de iska
better than the professor I have at my school :P
I love you Armando
Thank you so much 🙏💕
Awesome work! what kind of pens do you use?
thank you so much
Thanks a lot sir
Amazing! Afib made easy
In my experience I feel it’s important to know the ejection fraction to determine if patient has systolic or diastolic heart failure to treat with amiodarone or a ccb,bb. I’ve seen patient with an EF of 10-15 get cardizem and cause cardiac arrest.
Thank you so much...!!
Excellent
Love it bro
Fantastic 👌🏻👌🏻
Thank you
Thank you so much 🙏🙏🙏🙏🙏💙💙💙💙💙💙
Thank you for this explanation. My husband was just diagnosed with AF at young age of 50 . I now have a list of question to ask the cardiologist when he gets a referral. Sadly it sounds like he has persistent or permanent AF with high score for stroke since internal med doc is prescribing dabigatran before he even sees a cardiologist.
I have just been admitted to hospital with AF. I too am only 50. Lots of questions to be asked....
The best !!
amazing!
I also teach Biology.. you are my inspiration ❤️😍
It wno't be existed in biology

Can someone please explain WHY we use warfarin for valvular AF, whereas NOACs is for non-valvular AF?
thanks a lot
I love you armando
Thanks man
I'm confused. If it is an acute case, how do you have time to give 4 weeks anticoagulation before cardioversion? Please help
Thanks sir
I have a question and i can't figure it out. Why do we have irregular RRs in fibrillations but regular ones in flutter (taking the situation in witch the block is fixt)? As far as i understood, in flutter, the premature atrial waves can only "catch" the AV node outside of his refractory pause, thus leading the AV node to take "control" of the ventricular rhythm? But what about in fibrillation and it's irregular RRs?
Thanks
Problem is there are very little, if not, no videos online about what atrial fibrillation sounds like. I was exercising earlier and suddenly my heart rate accelerates to roughly 240 BPM and it was extremely loud and I could quite-literally feel it beating out of my chest, which was insane. Wasn't the first time either. Before, I was doing a running race and my heart rate was also extremely insane. Over 200 BPM then too, and I felt really faint like I wanted to pass out. I have had a weird history of shortness of breath I should also mention. I tried to get checked out when I was a bit younger, but was told there was nothing being reported as abnormal by a cardiogram. That relieved me, but now I'm starting to wonder if I should get checked out again.
Yes, you should get it checked out. Just to be sure

Is Apixaban now considered appropriate for anticoagulation in AF with enlarged Left Atrium,Enlarged Left Ventricle and Mitral Regurgitation (not stenosis) but without any artificial or prosthetic valves present?
amazing
What is the difference between and irregular arrythmia. Appreciate early reply. Rgds
❤❤❤❤❤❤❤❤❤thank you so much
What if the patient is a low BP person? And what if the heart rate also falls to below 60?
Damn nice video
Why wouldn't you want to talk about convergent hybrid ablation procedure for AF ??
Nice
Good work... I do some work ... You are welcome
My normal resting heart rate is in the range of 49 to 57. I drank a cold drink and had what I thought was a PSVT when I got brain freeze from drinking it too fast. My heart rate shot up to 96. I did a vagal maneuver and it dropped to 83. I splashed cold water on my face and it went down to 73. Over the next day it seemed to normalize and my heart rate has been in normal range since then but it seems inconsistent -- meaning slightly varied gaps between beats. I cant tell if Im stressed about this and causing it or if I have Afib with an otherwise normal 55 heart rate. I exercise fine. Could it just be stress lasting a few days?
Love you lotssssss❤❤❤ I love you too
the whole point of why this channel was good cuz that was real drawing in the earlier days. or at least i thought it was a real drawing.
What infinite paper do you use?
ok now someone tell me a name of youtube channel who teaches physic and chemistry as good as he teaches biology . i dont think there is one tbh .
