Objective To evaluate systematiclly the clinical efficiency and safety. Methods Choosing 14 RCT literatures which positive controlled by medicine such as atropine and aerolin and so on. There are 1014 cases which conclude treatment group 556 cases and control group 458 cases. Evaluate the efficiency and safety of yiqiwenyang treatment bradycardia arrhythmias by Meta analysis. Results Choosing 13 literatures which evaluation standard are clinical efficiency， and the results prompt that the clinical efficiency of yiqiwenyang is super than control group（OR=4. 27[3. 04，6. 01]）； There are 3 literatures which evaluation standard are mean heart rate， and the results point out that yiqiwenyang can promote mean heart rate obviously than medicine（OR=6. 58
[5. 27， 7. 89]）； Choose 3 literatures which safety evaluation standard are adverse reaction， and the results point out that the adverse reactions of yiqiwenyang are less than control group obviously（OR=0. 07[0. 02，0. 20]）. Conclusion It is safety and efficiency that yiqiwenyang treat bradycardia arrhythmias， and it is worth to generalize.
