The digital clinical guidelines could greatly improve the safety and quality of clinical diagnosis and treatment. However, most of such guidelines were written in engineering language, which was difficult for clinicians to understand in practice. To tackle this problem, we adoped the flowchart as the visual representation method of digital clinical guidelines. The corresponding criterions expressed by the flowchart were easily understood by clinicians. Then we set the digital clinical guidelines written in Arden syntax as an example, the interconversion between flowcharts and digital clinical guidelines was realized. The result of using the visual representation method proposed in this paper shows that the clinical diagnosis logic becomes clear and intuitive. So this is an effective method for clinicians to understand and edit the digital clinical guidelines.

It is very important to recognize arrhythmia in clinical electrocardiography (ECG) analysis. The fundamental of beat pattern recognition is presented in this paper. Various prevalent methods for arrhythmia recognitiion are categorized and summarized, based on which the advantages and disadvantages among the methods are compared, and the main problems are discussed in depth. At last, the development trend of arrhythmia recognition technology is pointed out.
