Abstract Objective To explore the significance of deceleration capacity of rate(DC) in early warning of acute myocardial infarction(AMI).Methods In our study, 200 patients were enrolled in AMI group who were attacked by AMI two weeks ago at most and restored sinus rhythm afterwards. Another 200 cases without AMI were divided into non-AMI group. All the candidates underwent 24-hour ambulatory electrocardiography. Their values of DC and acceleration capacity of rate(AC) were recorded and made early warning analysis. Results In AMI group, single vessel disease was found in 52 cases, two vessel disease in 98 and triple vessel disease in 50 while the numbers were 98, 68, and 34, respectively in non AMI group. For patients in AMI group, the mortality in one year was as follows: 2.00% if DC≥4.5 ms; 7.50% if DC was 2.6-4.4 ms; 10.05% if DC≤2.5 m, with statistically significant differences(P＜0.01). No death was reported in non AMI group,with variation of DC values. AC≤－7.0 ms,and no death was reported except for a mortality in one year of 1.00% in AMI group. Conclusion DC determination can quantitively analyze and measure the intensity of vagus nerve effect all alone, which proves to be significantly practical in screening and making early warning of AMI patients at high risk from sudden death.
