SigmaPace 1000
Operators Manual
The Analyzer begins the demand sensitivity test by measuring the pacemaker
pulse rate; then it places the selected waveform at 50 % of the pacemaker
pulse-to-pulse rate interval and initiates the protocol as stated in the main
product specification document.
The Analyzer response displays:
SENSE=XXX,ZZZ.ZZm,SYYYmV.
XXX is the waveform type, as indicated above.
ZZZ.ZZ is the pulse width.
YYY are the three-digit amplitude numeric reading, either with or without the
floating decimal point.
(Example: SENSE=SSQ,100mS,12.5mV for the sine-square selection @ 12.5
mV amplitude and width of 100 mS.)
SETTEST=NOISE
The Analyzer generates a sine wave at the power line frequency of either 50 or
60 Hz at a prescribed amplitude (Range: 0 to 10.0 mV in 0.50 mV steps) upon
the receipt of this command. Both the frequency and the amplitude of this sine
wave are encrypted in the following serial command structure.
The serial command structure is: NOISE=XX,nn.n where the XX represents
the power line frequency in Hz (50 or 60) and nn.n represents the amplitude in
millivolts. Example: NOISE=60,05.5 generates a sine wave at a frequency of
60 Hz at an amplitude of 5.5 mV.
ECG= ON
ECO=OFF
SETTEST=TREND
The Analyzer runs the prescribed trend test using 02 % to 20 % as the
deviation point from the computed average pulse amplitude, rate, and width.
TREND=uu,nnnn,zz,nnn
uu= % test limit for amplitude.
nnnn= Set point for amplitude (0.1 mA resolution.)
