二联
The episodes of bigeminy and ventricular tachycardia were sorted in descending order so that 10 longest episodes were always reviewed. 室性二联律和室性心动过速发作以递降顺序分类，所以总是要观察十次最长的发作。
Conclusion Expression of bigeminy and tachycardia of ventricular arrhythmia can reflect the cardiac ischemia more accurately than the number of simple ventricular premature beats. 结论：室性心律失常的联律和阵速的出现频率，比单发室性早博数量更能准确反应心肌缺血性改变的情况。
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. 结果：135例患者中，冠心病组室性心律失常更多地表现为多源性、联律、室速及R-ON-T现象，且R-ON-T现象明显多于非冠心病组。
alternating bifocal atrial bigeminy 交替性双灶房性二联律
alternating ventricular bigeminy 交替性室性二联律
