A total of 99 consecutive 24-hour Holter recordings with ventricular tachycardia were reviewed. Ventricular premature beats which occurred alone, and ventricular premature beats which initiated ventricular tachycardia were examined to determine which characteristics correlated with occurrence of ventricular tachycardia and which predicted rate and duration of ventricular tachycardia. The preceding R-R interval, the coupling interval, and a ratio of the two were examined. We found that ventricular tachycardia rate and duration increase with a shorter coupling interval, and the coupling interval/preceding R-R ratio was significantly different in single beats not initiating ventricular tachycardia. The ratio for the beat initiating ventricular tachycardia was smaller, indicating more prematurity.
回顾了总共99份连续的24小时伴有室性心动过速的动态心电图记录。对单独出现的室性早搏以及引发室性心动过速的室性早搏进行检查，以确定哪些特征与室性心动过速的发生相关，以及哪些特征可预测室性心动过速的速率和持续时间。检查了前一个R-R间期、配对间期以及两者的比值。我们发现，室性心动过速的速率和持续时间随着配对间期缩短而增加，在未引发室性心动过速的单个搏动中，配对间期/前一个R-R比值存在显著差异。引发室性心动过速的搏动的该比值较小，表明更早发生。
