Operators Manual
start the test until a pulse rate is detected. If the rate is between 30 and 200
PPM it waits for either of the following commands:
OVERDRIVE=nn
The Analyzer computes an 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
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.
UNDERDRIVE=nn
The Analyzer computes an 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.) 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 the 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 an 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
