Abstract
A device for automatically indicating a rate failure condition in a pacer monitoring the intrinsic pacer rate in both demand and fixed rate modes, including a first limit circuit preset at a low level of activity coupled to the monitoring means, and a second limit circuit preset at a high level of activity coupled to the monitoring means. A first switch is connected to the first limit circuit, and a second switch is connected to the second limit circuit. The first limit circuit responds to the combined rate of pacer and spontaneous activity falling below a preset level by placing the first switch in a switched condition, and the second limit circuit responds to the rate of pacer activity exceeding a preset level by placing the second switch means in a switched condition. Indicating means converts the switched conditions to distinguishable marking pulse signal for later clinical electrocardiogram detection.
