What are the key differences between pac and afib, and how do they impact a person's heart health?

PAC (Premature Atrial Contraction) and AFib (Atrial Fibrillation) are both heart rhythm disorders, but they have key differences. PAC is an early heartbeat originating in the atria, while AFib is a rapid and irregular heartbeat. PAC usually doesn't cause serious issues, but AFib can lead to blood clots, stroke, and heart failure. Both conditions can impact a person's heart health by affecting the heart's ability to pump blood effectively.
