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

Buy PDFs here: armandoh.org/shop
"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."

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'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.

[@dr.rafiulislam45]

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.

[@DenyTheFleshCalisthenics]

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.

[@michellejue2564]

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.

[@daveslayter4240]

I have just been admitted to hospital with AF. I too am only 50. Lots of questions to be asked....

[@litondas7646]

Nice

[@afrathegreat9053]

I'm confused. If it is an acute case, how do you have time to give 4 weeks anticoagulation before cardioversion? Please help

[@aymaaninamdar41]

Love you lotssssss❤❤❤ I love you too

[@user-qx4zc3nx8z]

Can someone please explain WHY we use warfarin for valvular AF, whereas NOACs is for non-valvular AF?

[@qamarkhan4339]

What is the difference between and irregular arrythmia. Appreciate early reply. Rgds

[@davidpowell3347]

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?

[@iasm2470]

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?

[@medicineandsurgery5948]

Good work... I do some work ... You are welcome

[@buqegashi7369]

[@Maggot1707]

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.

[@janet3782]

Yes, you should get it checked out. Just to be sure

[@alikangal4734]

benimde eforda 250 oldu son anda nabız

[@mangeshanaokar4451]

What if the patient is a low BP person? And what if the heart rate also falls to below 60?

[@sunc88]

👍👍👍

[@traceystock7352]

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?
