Initial experience of mobile cloud ECG system contributing to the shortening of door to balloon time in an acute myocardial infarction patient

Abstract

It is important for myocardial infarction patients to undergo immediate reperfusion of the affected coronary artery. In order to improve the prognosis, efforts to shorten the door to balloon time to within 90 minutes have been made. However, conventional methods such as faxing electrocardiograms (ECG) have not become widespread due to their high cost and lack of sharpness of the ECG. The "Doctor Car" (rapid response car system) of Kitasato University Hospital is now equipped with a Mobile Cloud ECG system. With this system, 12-lead ECG data obtained in the field are transmitted to the cloud server via a standard mobile telephone network. Since it uses an existing phone network, the cost of this system is low and it is fairly reliable. Cardiologists at the hospital read the ECG waveforms on the cloud server and decide whether emergency cardiac catheterization is necessary. In our first case using this Mobile Cloud ECG system, the door to balloon time could be shortened.
