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。

For example, ventricular bigeminy is when a premature ventricular contraction consistently comes after each normal cardiac cycle.
比如，室性二联律就是室性期前收缩在每个正常心动周期之后持续发生。
