[00:00:00]Let's revise with me. So, this is an image of atrial fibrillation.

[00:00:04]I hope you can appreciate there is a unequal RR interval.

[00:00:09]Also, there is no recognizable P wave.

[00:00:13]There is fibrillating F waves. Also, you can appreciate it's a narrow QRS complex. And the heart rate is 350 to 600. Though it can be fast ventricular rate or slow ventricular rate as well.

[00:00:26]Next, there is a common causes. The common causes are hypertension, CAD, valvular heart disease, heart failure, and the most important are chronic lung diseases and alcohol excess.

[00:00:39]About the clinical features, it consisting of palpitation, fatigue, dyspnea exertion, dizziness, lightheadedness, and reduced exercise tolerance. Syncope could be in some cases.

[00:00:52]The risk of stroke is there, so patient might be complaining of left-sided or right-sided weakness as well.

[00:00:59]In terms of management, first, we start with the rate control.

[00:01:04]If the patient is stable, then we start with the rhythm control with the amiodarone, then anticoagulant as per CHADS2 score to assess the risk of stroke, then treat the underlying causes. So, for the stable patient, we have an algorithm that is a less than 48-hour presentation. We start with the pharmacological cardioversion. And for the more than 48-hour presentation, we do transesophageal echo. In which, if we have a clot, then we start with the 3 weeks of anticoagulant followed by rhythm control, and then again 4 weeks of anticoagulant. The long-term anticoagulant will depend upon CHADS2 score. If the clot is absent, we start with the pharmacological cardioversion.

[00:01:45]So, this is it for the atrial fibrillation. Follow for more videos at Mediconcept PG.
