Definition: Antefibril, also known as atrial fibrillation, is a condition in which the heart's electrical system fails to keep rhythm. It is characterized by irregular heartbeat patterns and can cause symptoms such as shortness of breath, palpitations, dizziness, or fatigue. Antefibril occurs when the heart's pacemaker stops beating properly and causes the heart to beat too fast, leading to irregular rhythms. This condition requires medical treatment to restore normal rhythm and prevent further complications.
