Prehospital EKG Transmission via Cell Phone

Feasibility of early emergency room notification to improve door-to-balloon times for patients with acute ST segment elevation myocardial infarction.

An algorithm to lower time from first contact in the field by EMS personnel to in-hospital mechanical reperfusion is described. ECG tracings were telemetered via cellular phone to an emergency room physician, who then activated the cardiac catheterization call team to bypass usual delays seen during ER triage. Seventy-one ECGs were sent to the ER in the time interval from October 2003 to October 2004. Five ECGs (7.0%) failed to transmit due to failure of the cellular phone to receive an adequate signal. Sixty-six patients (93.0%) had an adequate ECG transmitted to the ER and six patients with ST elevation myocardial infarction were identified. Door-to-balloon times were lowered to 44 +/- 17.4 min, a substantial decrease over historical norms that range from 120 min (25th percentile) to 289 min (75th percentile).
