Causes of AFIB:  Know the Underlying Factors of Atrial Fibrillation


Atrial fibrillation(AFIB) is a type of arrhythmia or irregular heartbeat that occurs when the heart's upper chambers contract rapidly.

The most common cause of AFIB is age-related changes in the heart, such as the thickening of the heart muscle.

Monitor your heart rate, breathing rate, strain, heart rhythms, HRV, continuous ECG and a lot more using Frontier X2.

High blood pressure is a common risk factor for AFIB, as it can cause damage to the heart and lead to the development of AFIB.

Cardiac conditions such as heart disease, heart valve disease, and heart failure can also increase the risk of AFIB.

Chronic lung diseases, such as emphysema and chronic obstructive pulmonary disease (COPD) can cause AFIB.

Atrial fibrillation (AFIB) can also be caused by thyroid conditions like hyperthyroidism.

Drinking excessive amounts of alcohol can trigger atrial fibrillation(AFIB).

Other factors such as obesity, sleep apnea, and stress can also contribute to the development of AFIB. (Source: NHS.UK)
