If underlying cardiac disease like CHF is present, the treatment will also be directed towards its treatment, along with stabilizing the heart rhythm. Electrical shock therapy may be used to normalize the rhythm is some cases. If the fibrillation is a chronic problem (more than four months), the success rate drops accordingly and problem recurrence is common in these cases.
