Effect of a real-time tele-transmission system of 12-lead electrocardiogram on the first-aid for athletes with ST-elevation myocardial infarction

To study the effect of a real-time tele-transmission system of 12-lead electrocardiogram on door-to-balloon time in athletes with st-elevation myocardial infarction. a total of 60 athletes with chest pain diagnosed as st-elevation myocardial infarction (stemi) from our hospital were randomly divided into group a (n=35) and group b (n=25),the patients in group a transmitted the real-time tele-transmission system of 12-lead electrocardiogram to the chest pain center before arriving in hospital,however,the patients in group b not. the median door-to-balloon time was significant shorter in-group a than group b (38min vs 94 min,p<0.01) and the ratio of door-to-balloon time below 90 min was remarkable higher in-group a (94.2% vs 60%,p<0.01). the rate of catheter laboratory occupied was 5.7% in-group a and 40% in group b respectively (p=0.001). there was no statistically difference in mortality between the two groups (5.7% vs 4%,p>0.05). the median length of stay was significant reduced in-group a (5 days vs 7 days,p<0.01). real-time tele-transmission system of 12 lead electrocardiogram is beneficial to the pre-hospital diagnosis of stemi.
