Final answer:
Atrial fibrillation (Afib) is an irregular heart rhythm that increases the risk of blood clot formation in the lungs. It is important to receive medical treatment and management for Afib.
Step-by-step explanation:
Atrial fibrillation (Afib) is an irregular heart rhythm characterized by the heart's upper chambers (atria) beating fast and irregularly. This can lead to a variety of symptoms, including palpitations, shortness of breath, and fatigue. Afib increases the risk of blood clots forming in the heart, which can then travel to the lungs and cause a pulmonary embolism, a potentially life-threatening condition. Therefore, it is important for individuals with Afib to receive appropriate medical treatment and management.
