  • Rate-responsive pacemaker with minute volume determination and EMI protection
    Patent number: 5817136
    Abstract: A rate responsive pacemaker includes a noise sensor for sensing noise on the leads. If noise is detected, the pacemaker switches to a mode wherein a metabolic demand parameter is ignored. The noise is preferably detected by using test signals which are also used to measure the metabolic demand parameter.
