Abstract

Easy accessibility and affordability of the mobile phone network have made a mobile network-based tele-electrocardiography (ECG) a reality during the last 15 years. The instrument required for this purpose is very small compared to conventional ECG machines. It is lightweight, easy to carry and several folds lower in cost. Thus, it can be used in rural areas where there are no facilities available for managing cardiac emergencies. Many products are commercially available from domestic as well as international manufacturers. The technology has moved on from sequential 12 lead configurations to simultaneous 12 lead configurations; yet maintaining the overall size limited to credit card dimensions. Some of these have built-in interpretation algorithms (like Glasgow interpretation algorithm ECG), some offer cloud computing, whereas othersare developing their algorithms for incorporating diagnostic features. All these technologies are reviewed in this paper for comparison.
