Abstract：Objective To study the pathogeny and type of senile atrial fibrillation（AF）， analyze the related diameter of left atria and the anticoagulant treatment status. Methods Sixty two patients over 80 years old senile patients with AF were analysed. Results Patients with paroxysmal，prolonged and persistent AF accounted for 33.87%， 22.58% and 43.55%. Coronary artery disease is the most common etiology， followed by hypertension，valvular degeneration and electrolyte disorders.As compared with prolonged AF and persistent AF， the left atrial diameter of paroxysmal AF was smaller，which showed a significant difference（P<0.05）. Among 62 patients the occurrence of arterial embolization was 22 cases（35.48%）; Cerebral stroke was 20 cases（32.26%）. 21 of patients did not receive any anticoagulation therapy. Conclusion Coronary heart disease and hypertension is the common cause of senile AF. Stroke is one of the important complications，66.13% of patients received antithrombotic therapy with antiplatelet therapy. Antithrombotic treatment for senile patients with atrial fibrillation should be cautious.
