1. The episodes of bigeminy and ventricular tachycardia were sorted in descending order so that 10 longest episodes were always reviewed.

2. Conclusion Expression of bigeminy and tachycardia of ventricular arrhythmia can reflect the cardiac ischemia more accurately than the number of simple ventricular premature beats.

3. Results Ventricular arrhythmia in patients with coronary heart disease showed more pleomorphism, bigeminy, ventricular tachycardia and R-ON-T phenomena than patients with non-coronary disease.

4. Methods: 60 cases were selected and divided randomly into control group and treatment group, the latter by bigeminy therapy with the decoction and Omeprazole ECT, the former by Omeprazole ECT only.

5. Four types of abnormal ECG including sinus arrythmia(28.0%)sinus arrest(4.0%), sinus bigeminy(4.0%) and atrial flutter(4.0%) were showed in the Han-sheep with small-tail examined.
