The Analyzer computes a dual (AV) channel overdrive (higher) ECG signal
rate based upon the earlier measured pacemaker pulse rate. A two-digit
number (nn) represents the percentage that ECG signal is higher than the
measured pacemaker pulse rate. (Example: With a measured pacemaker pulse
rate of 60 PPM and the following overdrive command of OVERDRIVE=20, a
computed ECG signal rate of 72 BPM is generated.)
All serial commands that do not return data or a predetermined response send
OK to indicate that the serial command was received, understood and
executed. The pacemaker will either PASS or FAIL this qualitative test based
upon the criteria stated in the main product specification document.
UNDERDRIVE=nn
The Analyzer computes a dual (AV) channel underdrive (lower) ECG signal
rate based upon the earlier measured pacemaker pulse rate. A two-digit
number (nn) represents the percentage that ECG signal is lower than the
measured pacemaker pulse rate. (Example: With a measured pacemaker pulse
rate of 60 PPM and the following underdrive command of
UNDERDRIVE=20, a computed ECG signal rate of 48 BPM is generated.)
All serial commands that do not return data or a predetermined response shall
send OK to indicate that the serial command was received, understood and
executed. The pacemaker will either PASS or FAIL this qualitative test based
upon the criteria stated in the main product specification document.
SETTEST=ASYNC
The Analyzer begins this async test by measuring the pacemaker pulse rate; if
it is ZERO, the Analyzer transmits RATE=000 and will not start the test until a
pulse rate is detected.
OVERDRIVE=nn
The Analyzer computes a dual (AV) channel overdrive (higher) ECG signal
rate based upon the earlier measured pacemaker pulse rate. A two-digit
number (nn) represents the percentage that ECG signal is higher than the
measured pacemaker pulse rate. (Example: With a measured pacemaker pulse
rate of 60 PPM and the following overdrive command of OVERDRIVE=20, a
computed ECG signal rate of 72 BPM is generated.) The pacemaker will
either PASS or FAIL this qualitative test based upon the criteria stated in the
main product specification document.
