Atrial Fibrillation: Understanding the Main Symptoms and Risks

Atrial fibrillation, commonly referred to as AFib, is a serious cardiac arrhythmia caused by chaotic electrical activity in the atria of the heart. This condition is particularly prevalent among older adults, especially those with pre-existing cardiovascular conditions. One of the most concerning aspects of AFib is its potential to lead to secondary complications such as blood clot formation.

Recognizing the Common Symptoms of Atrial Fibrillation

In cases where the heart's ventricular rate remains stable, individuals may experience no noticeable symptoms at all. However, when the ventricular rate increases, typical signs may include palpitations, fatigue, chest discomfort, and excessive sweating. These symptoms can significantly affect a person's quality of life and daily activities.

Understanding the Risks of Blood Clots and Stroke

One of the most dangerous complications associated with AFib is the formation of blood clots in the heart. If a clot dislodges and travels to the brain, it can cause a stroke. Symptoms of such an event may include facial drooping, slurred speech, weakness or numbness in the limbs, sensory disturbances, and confusion.

Severe Complications and the Importance of Early Detection

In more severe cases, atrial fibrillation can lead to life-threatening conditions. Stroke-related complications can result in long-term disability or even sudden death. Therefore, early diagnosis and effective management of AFib are crucial in preventing these serious outcomes and improving patient prognosis.
