![]() ![]() This type of AF may present as the first episode or as a result of recurrent episodes of paroxysmal AF. In this case, the episodes last more than seven days, and if it is associated with a rapid and uncontrolled ventricular rate, it may lead to electrical remodeling in the cardiac myocytes causing dilated cardiomyopathy. Persistent AF: If recurrent AF persists, needing either pharmacological or electrical cardioversion, it is called persistent AF. Elimination of these foci is found to be effective in treating this type of AF since it eliminates the trigger for such episodes. In younger patients, paroxysmal AF has been commonly found to be secondary to electrically active foci within the pulmonary veins. Here, the episodes terminate spontaneously within seven days. Paroxysmal AF: If recurrent AF reverts spontaneously, it is called paroxysmal AF. The three patterns of atrial fibrillation include: Ītrial fibrillation is referred to as recurrent when a patient has two or more episodes. Inflammation - myocarditis and pericarditisĪny condition that leads to inflammation, stress, damage, or ischemia affecting the anatomy of the heart can result in the development of atrial fibrillation. Treatments include anticoagulation, rate control medication, rhythm control medication, cardioversion, ablation, and other interventional cardiac procedures. ![]() Although atrial fibrillation may be a permanent disease, various treatments, and risk modifying strategies have been developed to help reduce the risk of stroke in patients that remain in atrial fibrillation. ![]() Symptoms vary from asymptomatic to symptoms such as chest pain, palpitations, fast heart rate, shortness of breath, nausea, dizziness, diaphoresis (severe sweating), and generalized fatigue. Atrial fibrillation is the leading cardiac cause of stroke. Risk factors for atrial fibrillation include advanced age, high blood pressure, underlying heart and lung disease, congenital heart disease, and increased alcohol consumption. Due to its rhythm irregularity, blood flow through the heart becomes turbulent and has a high chance of forming a thrombus (blood clot), which can ultimately dislodge and cause a stroke. It is characterized as a tachyarrhythmia, which means that the heart rate is often fast. This arrhythmia may be paroxysmal (less than seven days) or persistent (more than seven days). It is due to abnormal electrical activity within the atria of the heart, causing them to fibrillate. Atrial fibrillation is the most common type of cardiac arrhythmia. ![]()
