Cardiac pacer system

Abstract From the Canadian patent

A pacer for cardiac pacing and condition monitoring wherein the electrical characteristics of the pacer are altered upon a temporary or permanent change in monitored conditions, such as loss of capture or failure to sense. The monitor acts to provide both increased stimulus to recover capture and to provide warning pulses indicating loss of capture or failure to sense, which are sufficiently discernible upon an electrocardiogram to enable later diagnosis even after self-correction. After diagnosis the monitor can, be reset to its original condition by means of an external control, such as a magnet. The unit may be surgically implanted or employed externally. - 1 -
