Abstract：This paper introduces Professor XU Minhua's ideas on the treatment and the characteristics of prescriptions and medication for arrhythmia. Professor XU Minhua believes that nowadays， with the sharp increase of social pressure，there exist the increase of depression and anxiety，the disorderly qi flow in the liver and the gallbladder qi with timidity， resulting in disquieted heart qi. In the treatment of arrhythmia， it is necessary to "tranquilize the heart spirit" to calm the palpitation. At the same time， the whole should be focused on，because "the disease is in the heart，but not just in the heart". Yin and yang should be speculated，qi and blood be regulated，and the five zang organs be treated together. There is no need to be restricted to major or compound prescriptions to dispel pathogen qi and reinforce healthy qi. All the principles above can contribute to a stable and lasting clinical effect. In clinic，the herbs can be Radix Sophorae Flavescentis，root of Radix et Rhizoma Rohdeae Japonicae，Rhizoma Coptidis and others，and the prescriptions can be Pujin powder，Xiaoxianxiong tang，Wushen tang，Guizhi，Longu Muli tang and so on.
