Abstract
Perfeccionamientos en aparatos de adquisición y de pretratamiento de datos electrocardiográficos que comprenden órganos de multiplexaje, de preamplificación y de conversión de las señales captadas por los electrodos, órganos de amplificación de las componentes escalares que resultan de la conversión y órganos de visualización de estas componentes asociándose estos órganos, en un conjunto transportable, a medios de conversión analógica-numérica de las citadas componentes escalares y a un micro-procesador, caracterizados porque el micro-procesador es programado para aplicar impulsos de calibrado y señales de control a la entrada de la cadena de preamplificación, de conversión y de amplificación para la puesta a tensión del aparato y para analizar la respuesta de la cadena a los impulsos y a las señales, con vistas a determinar su ganancia y su banda pasante y para controlar una operación de puesta a cero de la línea de base de loas componentes escalares, por una parte, a intervalos fijos quecorresponden a un espacio de tiempo de secuencias de adquisición que se encadenan automáticamente, y por otra parte al principio y al final de calibrado.
