Study on the Impacts of remote real-time transmission 12-lead electrocardiogram system on door-to- balloon time in patients with ST-segment elevation myocardial infarction

Abstract

Objective This study was aimed to evaluate the remote real-time transmission 12-lead electrocardiogram system on door-to-balloon time in patients with ST-segment elevation myocardial infarction. Methods We retrospectively analyzed the consecutive patients with STEM I who had accepted primary percutaneous coronary intervention (PCI) in the chest pain center of our hospital from February 2012 to July 2012. The study group consisted of patients with pre-hospital ECG, while the control group included patients without pre-hospital ECG, Their door-to-balloon time and door-to-catheter room time, mortality w ere compared. Results Totally 60 consecutive patients who had received primary PC I for STEMI were evaluated. Among them, 35 patients were hospitalized with pre-hospital ECG while the other 25 patients without ECG. The Pre-hospital ECG was associated with a significantly shorter median door-to-balloon time (38 min vs. 94min; P 0.05), Significant difference was seen in the median hospital time in study group (5 compared with control group (7day) (5 day vs. 7 day ; P <0.01). Conclusions The remote real-time transmission 12-lead electrocardiogram system is associated with a significantly shorter door-to- balloon time in STEMI patients. The remote real-time transmission 12-lead electrocardiogram system is recommended in patients suspected STEMI.
