What Is the Difference Between Cardiac Arrhythmia and Atrial Fibrillation?

Cardiac arrhythmia is sometimes called irregular heartbeat or cardiac dysrhythmia. It refers to a group of conditions in which a person’s heartbeat becomes irregular, either too fast or too slow. There are many types of cardiac arrhythmia, including tachycardia in which the person’s heartbeat is above 100 beats per minute and bradycardiac in which the person’s heartbeat is below 60 beats per minute.

Atrial fibrillation is also a type of cardiac arrhythmia, and it is the most common one. It’s a problem in your heart’s electrical activity. The heart is divided into upper chambers (atria) and the lower chambers (ventricles). It contracts and relaxes regularly with the cooperation of atria and ventricles to make the blood in your body circulate. In AFib, something goes wrong with the atria, so the heartbeat becomes racing and fluttering.
