Abstract Objective To study the predictive value of testing technology of deceleration capacity of rate（DC） to malignant ventricular arrhythmias sudden cardiac death. Methods Comparative analysis of the deceleration capacity of rate were done between the observation group of 8 patients with sudden cardiac death and 17 patients with malignant ventricular arrhythmias and the control group of 28 patients with no sudden cardiac death or malignant ventricular arrhythmias. Results Standard by DC<4.5 ms as abnormal and DC<2.5 ms as significant abnormal，the DC variation of the observation group was obviously higher than that of the control group. Conclusion The deceleration capacity of rate has predic- tive value for malignant ventricular arrhythmias sudden cardiac death， and DC<2.5 ms as the abnormal standard has clinical practicality.
