The goal of this prospective-enrolling cohort study is to test and observe the effect of an integrated multi-discipline care program in patients with atrial fibrillation. The main questions it aims to answer are:

1. to understand the baseline characteristics and to explore the occult risk factors of the patients with AF;
2. to monitor the treatment efficacy of the patients undergoing integrated care and potentially concur the clinical obstacles that prevent the best care for patients with AF.

Participants will be treated by an integrated multi-discipline team that led by an electro-physiologist.

Atrial fibrillation (AF) is a heart condition that potentially leads to heart failure and ischemic stroke. The prevalence of AF is increasing due to aging population and improved treatment in other cardiovascular field. This study is to execute integrated multi-discipline care in a tertiary hospital, and to observe the effect and the obstacle that the program might ensue.

Inclusion Criteria:

• At least 18 years old, who have been diagnosed with atrial fibrillation by a cardiologist with an electrocardiogram

Exclusion Criteria:

1. Unable to complete the initial assessment and cooperate with the tracker
2. Those who refuse to sign the subject's consent

Adult patients with documented atrial fibrillation, either paroxysmal, persistent, or permanent.
