Atrial Fibrillation Cardioversion
If you have an abnormal heart beat for example atrial fibrillation your physician may want you to have a treatment called cardioversion. If AF is a risk indication, terminating it would not be expected to have an impact on the clinical result. Candidate outcomes for measuring the impact of conversion and maintenance of sinus rhythm include stroke, death, ventricular function or heart failure, and Symptoms of Atrial Fibrillation.
In spite of deficient in of verification, many physicians continue to believe that restoring and maintaining sinus rhythm has a positive impact on the risk of stroke and death and removes the need for anticoagulation. Indeed, until recently, the standard for regulatory approval of a new Treatment for Irregular Heartbeat was the demonstration that the treatment was better to placebo with respect to maintenance of sinus rhythm. In reality, the worth of the Atrial Fibrillation Cardioversion and maintenance of sinus rhythm must be careful in terms of its impact on the consequences of atrial fibrillation.
The instant success rate of electrical Atrial Fibrillation Cardioversion using current technology is high, approaching or slightly exceeding 90% in those enrolled in randomized trials.6 It may be lower than that in unselected study populations, but is maybe still more than 80%.7 Immediately terminating AF has at least 1 other potential drawback. One of the scourges of electrical cardioversion is immediate or initial recurrence of AF.
The greatest feared complication of Atrial Fibrillation Cardioversion is stroke or systemic embolism. The risk of stroke or systemic embolism is less of a problem for pharmacological cardioversion, because this therapy is generally applied very initial after the onset of Atrial Fibrillation.
