Brief Answer:
No causative relationship between the two

Detailed Answer:
Hello and Welcome

I appreciate your concern


Tobacco smoke contains nicotine, carbon monoxide, and polycyclic aromatic hydrocarbons which can lead and contribute to arrhythmias like atrial fibrillation.
Smoking causes endothelial damage and can lead to rhythm disorders.
Cigarette smoking is a known risk factor for cardiovascular disease, however, there is no conclusive evidence to specifically link tobacco smoking with a causative relationship to the risk of atrial fibrillation.

Wishing you best of health

Thanks

Dr. M.S. Khalil
