The latest in external cardiac pacemaker
analyzers.
This new biomedical instrumentation test
product shall satisfy the biomed's wide
range of external transcutaneous
(non-invasive) and transvenous
(invasive) pace-maker testing needs. The
SigmaPace™1000 is a powerful handheld
analyzer with a comprehensive range of
test suites, measurement algorithms and
test loads—as specified by the external
pacemaker manufacturers—to fulfil your
testing requirements both fast and
efficiently.
The biomedical technician can check
external pacemakers for basic operation,
verify pace-maker performance either
during routine inspections or following
factory repair/upgrade, and troubleshoot
intermittent pacemaker problems.
The SigmaPace™1000 will also prove to be
a valuable in-service training and
demonstration tool. In addition to the
ability of demonstrating the pacemaker's
basic amplitude sensitivity and
refractory capabilities, you can also
present the interactive pacemaker
operation using either the standard
5-Lead or high-level ECG output with
your bedside monitor, strip chart
recorder or oscilloscope. The SigmaPace™1000
realistically mimics the patient's
cardiac response to the attached
temporary pacemaker including capture,
the basic transcutaneous pacemaker
asynchronous operation and the more
complex four states of dual channel
transvenous pacemaker operation.
True dual-channel measurement and
embedded DSP (Digital Signal Processor)
technologies meet the performance
challenge!
Earlier analyzers have only one
measurement channel whereas the
SigmaPace™1000 offers two independent
analogue-to-digital conversion channels
that simultaneously capture the
pacemaker's arterial and ventricular
output pulses. The pacer output
pulses—now in digital format—are fed to
the digital signal processor (DSP) where
all calculations are conducted. Now the
biomed can take a fast and accurate
"snapshot" of pacemaker operation…
simultaneous dual channel measurement
data is displayed on the LCD readout and
available via the serial port!
Testing is a breeze with the SigmaPace™1000
because you no longer need to switch
test leads to conduct your desired
arterial or ventricular channel test… all
test functions with the required ECG
waveforms are instantly available to the
user though via internal relay routing.
As you would expect, the SigmaPace™1000
maintains high differential isolation
impedance between the arterial and
ventricular channels during pulse output
tests to ensure accurate measurements.
