RESUMEN
Antecedentes La transmisión telefónica del electrocardiograma (ECG) a un centro do análisis ha permitido el diagnostico precoz del infarto agudo del miocardio (IAM), incluso en lugares remotos de nuestro país. La ley AUGE exige el tratamiento inmediato del IAM con trombolisis y/o e/ traslado del paciente a un centro de referencia para su ulterior tratamiento.

Objetivo:

Tabular las características demográficas, distribución geográfica de la población estudiada, fecha y hora de presentación del IAM.

Métodos:

De un total de 523.371 ECG se analizaron 3.656 trazados con lesiones subepicárdicas definidas por desnivel superior de ST de a lo menos de 1 mm en dos o más derivaciones consecutivas (IAM con SDST). Los ECG fueron adquiridos con sistemas Aerotel 0 Cardiette y analizados por dos cardiólogos.

Resultados:

Se confirmo la mayor incidencia de IAM en hombres (69.2 por ciento vs 30.8 por ciento) y la presentación del IAM a una edad mayor en mujeres. Se registró un mayor numero de IAM entre los meses de Abril y Julio, y entre las 09 y 13 horas. Los tiempos de respuesta del sistema desde el momento de la recepción del ECG hasta el envío del informe no supero los 10 min, a cualquier hora del día a la noche, tanto en días hábiles como no hábiles.

Conclusión:

Se consignaron antecedentes epidemiológicos del IAM en el país, a la vez que se comprobó que el sistema permite un diagnostico precoz del IAM, lo cual puede tener un impacto positivo en el tratamiento de esta patología.
ABSTRACT

Background:

Telephonic transmission of an electrocardiogram (ECG) from rural areas to a center with cardiologist in place to analyze the records has been recently incorporated in Chile, allowing earlier diagnosis of an Acute Myocardial Infarction, even in remote places. Such early diagnosis should prompt faster thrombolysis or primary angioplasty.

Aim:

To descnbe demographics of the population in which diagnostic ECG were taken, plus date and time of the day when the diagnosis of AMI was made.

Method:

Out of 523.371 ECG, we identified 3.656 records with epicardial lesions, defined as ST elevation of at least 1 mm in 2 concordant leads (STEAM!). The records were obtained with systems Aerotel or Cardiette, and were analyzed by 2 cardiologists.

Results:

We found higher incidence of STEAMI in man (69.2 percent vs 30.8 percent). Older age was more frequently seen in women with STEAMI. A higher incidence of STEAMI was found between April and June, being more frequently observed between 9 AM and 13 PM. The delay between the reception of the ECG and its interpretation was no longer than 10 mm, regardless the time of the day. and including holidays

Conclusion:

We confirmed some epidemiological data regarding STEAM! in Chile. This technology allows the early diagnosis of the STEAM! fiom remotes areas of our country.
