pitvarfibrillációban

Pitvarfibrillációban, often translated as Atrial Fibrillation (AFib) in English, is the most common type of cardiac arrhythmia. It is characterized by rapid and irregular electrical activity in the atria, the two upper chambers of the heart. This chaotic electrical signaling causes the atria to quiver or "fibrillate" instead of contracting effectively. As a result, blood flow through the atria becomes turbulent, and the ventricles, the lower chambers, may receive electrical impulses irregularly, leading to a rapid and often irregular heartbeat.

The causes of pitvarfibrillációban are varied and can include underlying heart disease, high blood pressure, thyroid problems, diabetes, and lifestyle factors such as excessive alcohol consumption or obesity. In some cases, the cause may not be identifiable. Symptoms can range from none at all to palpitations, shortness of breath, fatigue, dizziness, and chest pain. The irregular heart rhythm can impair the heart's ability to pump blood efficiently, increasing the risk of stroke due to blood clots forming in the fibrillating atria and traveling to the brain.

Diagnosis typically involves an electrocardiogram (ECG) to assess the heart's electrical activity. Treatment aims to control the heart rate, restore a normal heart rhythm if possible, and prevent complications, particularly stroke. Medications such as beta-blockers, calcium channel blockers, and antiarrhythmics are commonly used. Blood thinners are often prescribed to reduce the risk of stroke. For some individuals, procedures like electrical cardioversion or catheter ablation may be considered to correct the heart rhythm. Lifestyle modifications can also play a significant role in managing pitvarfibrillációban.
