Abstract
The ability of an ecg apparatus to detect and display pacing pulses from the surface electrodes on a patient in whom a minute ventilation-based rate adaptive pacemaker is implanted is improved by providing the ecg apparatus with a minute ventilation detection circuit capable of indicating the time of occurrence and repetition rate of bursts of AC carrier signals which the implanted pacemaker generates in deriving a minute ventilation related control signal for the implanted pacemaker. In addition to improving the ability of the ecg system to detect and record paced events, the incorporation of the MV detection into the ecg system accommodates leads-off detection by coordinating the generation of the leads-off drive signal with the MV carrier signal generated by the implanted pacer.
