Atrial fibrillation and hypertension - increase the risk of Stroke

It is more important to recognize the atrial fibrillation and treat it  to prevent the stroke related morbidity.AF increases the risk of stroke. The degree of increase can be substantial, depending on the presence of additional risk factors (such as high blood pressure). Atrial fibrillation may be treated with medications to either slow the heart rate to a normal range ("rate control") or revert the heart rhythm to normal ("rhythm control"). Synchronized electrical cardioversion can be used to convert AF to a normal heart rhythm. Surgical and catheter-based ablation may be used to prevent recurrence of AF in certain individuals. Depending on the risk of stroke and systemic embolism, people with AF may use anticoagulants such as warfarin, which substantially reduces the risk but may increase the risk of major bleeding, mainly in geriatric patients. The prevalence of AF in a population increases with age, with 8% of people over 80 having AF. Chronic AF leads to a small increase in the risk of death.

Four types of Atrial fibrillations!!

All atrial fibrillation patients are initially in the category called first detected AF. These patients may or may not have had previous undetected episodes. If a first detected episode self-terminates in less than 7 days and then another episode begins later on, the case has moved into the category of paroxysmal AF. Although patients in this category have episodes lasting up to 7 days, in most cases of paroxysmal AF the episodes will self-terminate in less than 24 hours. If instead the episode lasts for more than 7 days, it is unlikely to self-terminate,^[2] and it is called persistent AF. In this case, the episode may be still terminated by cardioversion. If cardioversion is unsuccessful or it is not attempted, and the episode is ongoing for a long time (e.g., a year or more), the patient's AF is called permanent. Episodes that last less than 30 seconds are not considered in this classification system. Also, this system does not apply to cases where the AF is a secondary condition that occurs in the setting of a primary condition that may be the cause of the AF.
