The ecg recorder of claim 5 wherein the minute ventilation detection circuit comprises: (a) a matched filter coupled to receive said signals picked up by the pairs of surface electrodes, along with signals of said given frequency and producing an output; and (b) a comparator coupled to receive the output of the matched filter, along with a reference signal, the comparator producing an output indicating the time of occurrence of the components due to the carrier signal when the output of the matched filter exceeds the reference signal. 7. The ecg recorder of claim 6 and further including: (a) a frequency detector coupled to the minute ventilation detection circuit for monitoring the repetition rate of said timed bursts; and (b) a reference signal adjustment device for varying the reference signal in response to an output from the frequency detector. 8. The ecg recorder of claim 7 wherein the reference signal adjustment device is operative to increase the reference signal when timed bursts occur at a repetition rate greater than the predetermined repetition rate and to decrease the reference signal when the timed bursts occur at a repetition rate less than the predetermined repetition rate.9. An ecg recorder for detecting and displaying cardiac signals picked up on a plurality of surface electrodes disposed on a patient at predetermined body locations in whom a rate-adaptive cardiac rhythm management device is implanted, the ecg recorder intermittently applying an AC signal to one of said plurality of surface electrodes to determine the state of conduction between the other of said plurality of surface electrodes and the patient's skin, the cardiac rhythm management device being of the type having minute ventilation as a control parameter for the rate at which the device produces pacing pulses, the device having a means impressing a carrier signal of a given frequency close to said AC signal in timed bursts of a predetermined repetition rate between a first electrode in the patient's thoracic cavity and a reference electrode, comprising: (a) a minute ventilation detection apparatus in the ecg recorder connected to receive signals picked up by pairs of said surface electrodes, the signals picked up by the pairs of said surface electrodes, including cardiac signal components, pacing pulse components, noise components, components due to said carrier signal and operative to indicate the time of occurrence of the components due to said carrier signal; and (b) control means responsive to the minute ventilation detection apparatus for causing the AC signal applied to said one of said plurality of surface electrodes to be interlac
