Abstract

En esta Patente de Invención se describen un método y un aparato para obtener información del sistema cardiovascular latido a latido y de forma continua, que están basados exclusivamente en mediciones entre dos extremidades y realizadas con un par de electrodos distales en cada una de ellas. La medida se realiza haciendo circular una corriente alterna entre un electrodo de cada extremidad y midiendo la diferencia de potencial entre los otros dos electrodos, uno también en cada extremidad. Esta diferencia de potencial tiene una componente de baja frecuencia que es el electrocardiograma (o ECG) y otra componente que tiene la frecuencia de la corriente alterna inyectada y de la que se extrae el denominado pletismograma de impedancia (IPG, del inglés impedance plethysmogram). La información cardiovascular se determinará midiendo el lapso entre algún elemento característico predefinido del ECG y alguno del IPG.
