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

ABSTRACT

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
