Transvenous Pacemaker Remote Setup and Testing
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.)
The pacemaker will either PASS or FAIL this qualitative test based upon the
criteria stated in the main product specification document.
SETTEST=RFRACTA
SETTEST=RFRACTV
REFRACT=zzz,nnn.nn,nnn
zzz= SQU,TRI,SSQ,HSN
nnn.nn= Width in mS
nnn= Amplitude in mV
The Analyzer begins the refractory 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. The paced refractory period is computed, then
reported in the following format: PRP=XXX mS. The sensed refractory period
(SRP) is computed and reported in the following format: SRP=XXX mS. Note
This reported data has three-digits and no displayed decimal point. It
returns A=PRP=248mSRP=253mS.
SETTEST=SENSEA
SETTEST=SENSEV
The single-channel demand sensitivity test can run either on the atrial or the
ventricular channels with one of three different waveforms: square, triangle
and sine-squared at one of six pulse widths. Set the test to SENSE, then select
the desired waveform for the test, and finally set the pulse width.
SENSE=SQU, nnn.nn
SENSE=TRI, nnn.nn
