Abstract 163: Use of a Free, Non-proprietary Iphone App (STEMISend) to Substantially Improve Pre-hospital ECG Transmission Capability

Introduction: Pre-hospital diagnosis of ST-segment Elevation Myocardial Infarction (STEMI) promotes pre-arrival decision making and minimizes reperfusion delays. However, many commercial ECG transmission systems are expensive and based on proprietary technology. Recent advances in phone and app technology suggest another approach. As an alternative, a smartphone app (STEMISend) was developed and partnered with an inexpensive cell signal booster. This combination was then tested in multiple head-to-head comparisons with commercial systems. Results showed the app + booster approach to be non-inferior or superior to commercial systems -particularly in signal-limited environments. Hypothesis: Based on preliminary testing, the STEMISend smartphone app was suggested as a cost-effective alternative to commercial systems. Extensive field testing looking at percent success, cycle reliability and comparative performance in low-signal environments was conducted. Procedure: The STEMISend/booster combo was field-teste...
