Atrial Fibrillation AF And Stroke

Atrial fibrillation (AF) is a condition that causes an irregular heart rate. During this procedure, we try to isolate the abnormal signals that initiate the atrial fibrillation. As the signal passes through the AV node to the ventricles, it signals the ventricles to contract, pumping blood out to your body. In patients with troublesome, permanent AF, a surgical procedure may be done as a last resort to stop the conduction of all impulses from the atria to the ventricles (complete heart block ), together with the implantation of a permanent pacemaker.

Restoring and maintaining a normal heart rhythm is a treatment approach recommended for people who aren't doing well with rate control treatment.

In those with a fast ventricular response, intravenous magnesium significantly increases the chances of successful rate and rhythm control in the urgent setting without major side-effects. While it is not immediately life-threatening in the same way as some arrhythmias, it can lead to heart failure or stroke and so it has potentially serious effects.

The Holter monitor is helpful if you have only occasional bouts of atrial fibrillation that do not show up on an ECG. AF may be classified based on aetiology, depending on whether it occurs without identifiable aetiology in patients with a structurally normal heart (lone AF), or whether it complicates hypertensive, valvar, or other structural heart disease.

In fact, the atria beat so quickly that the lower heart chambers (the ventricles) can't quite keep up, and your heart doesn't beat in the usual, coordinated manner. Although electrical cardioversion can be used to treat almost any abnormal fast heartbeat (such as atrial flutter and ventricular tachycardia), it is used most frequently to convert atrial fibrillation to a normal rhythm.

If patients experience serious clinical symptoms, such as chest pain or shortness of breath related to the ventricular rate, the health care professional in the emergency department will try to decrease the heart rate rapidly with intravenous (IV) medications.

In some people who have AF for the first time, doctors may choose to use an electrical procedure or medicine to restore a normal heart rhythm. 31. Mason PK, Lake DE, DiMarco JP, et al. Impact of the CHA2DS2-VASc score on anticoagulation recommendations for atrial fibrillation.

Atrial fibrillation is a form of tachycardia. Another procedure to restore a normal heart rhythm is called maze surgery.
