Atrial Fibrillation Overview - ECG, types, pathophysiology, treatment, complications

"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."

I feel this is one of the most lucid videos on AF, not missing or messing a single event. Really an wonderful study. Thanks

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.

[xdays]

I have been diagnosed with Paroxsysmal Afib and am scheduled for an ablation in 3 weeks. I have been overdosing on YouTube 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!

[dikshadhawan]

Never seen anybody explaining such a difficult topic so beautifully.

[BigPilisos]

I am a resident and still watching your videos. You were my hero through med school and still are <3

[Prettyvannaaa]

I am 21and have A FIB & a pacemaker since I was 16... thank you for this video.

[brianfoley]

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.

[kegsl]

One of the best presentations on AF. Good job!

[bhavanatiwari]

who's a life saver ? YOU'RE A LIFE SAVER ! :')
Thank you so much .
Please keep uploading new videos

[blueeyes]

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.

[donyadadvand]

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 😘

[michelandre]

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.

[ijeuna]

Your videos and illustrations have come so far since the beginning!!! Love and respect your channel and your hustle!

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.

[KarinaNangolo]

I am currently studying Atrial Fibrillation, this video just came at the right time. Thank you for making it more easy. 😍💪🏾

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.

We're just about to take a big exam on cardiac tomorrow morning !! So glad I remembered your page!

Amazing illustration with detailed information. It was really helpful! Thank you for making the complicated UNCOMPLICATED! :)
