Introduction
Basic concept
The WhaleTeq Single Channel ECG Test System 5.0 (SECG 5.0 AIO) provides a single
waveform to one or more lead electrodes of diagnostic, ambulatory or monitoring ECGs, for
testing to IEC/YY/JJG particular standards. The following diagram shows the single channel
concept:
(Figure 1) Single Channel Concept
Via a SECG 5.0 AIO, the system produces voltage up to 40 mVpp. The SECG 5.0 AIO contains
resistor/capacitor networks, dc offset, pacing circuit and relay switching to provide the full
range of single channel performance tests in IEC/YY/JJG standards.
The basic range of tests in the standards include, for example:
-
Sensitivity (accuracy of the mV/mm indication)
-
Frequency response (sine wave, and impulse tests)
-
Input impedance
-
Noise
-
Multichannel cross talk
-
Accuracy of heart rate indication
-
Pacemaker rejection
-
Tall T-wave rejection
For a full list of tests, refer to the standard together with Section 1.2.
The system does not provide:
-
CMRR tests (this requires a special low-noise test equipment, please to CMRR series
test systems on WhaleTeq website)
-
Multichannel waveforms, such as the CSE, AHA, MIT databases (this requires a
multichannel system, please refer to MECG 2.0 on WhaleTeq website)
