　　1. Animal modeling materials: guinea pigs; Drug: Adenosine; Equipment: Biological function experimental system.

　　2. Modeling method: Animals inject adenosine into the left atrium from the left atrial appendage μ g. Inject for about 1 second.

　　3. Modeling principle: Adenosine induces conduction block type arrhythmia and establishes an animal model.

　　4. After injection of changes after modeling, typical atrioventricular block of degree II or III or above can occur. In more severe cases, complete atrioventricular arrest occurs, and the duration of cardiac arrest is parallel to the dose. Heart rate and rhythm can only recover in a few seconds or more.
