Note:
Early myocardial infarction: normal Q-wave, ST elevation or ST slope elevation
Acute myocardial infarction: abnormal Q-wave, ST elevation or ST slope elevation
Old myocardial infarction: abnormal Q-wave, no ST elevation.
Abnormal Q-wave:
For leads I, II, III, avR, avL, avF, V3, V4, V5, V6, voltage of Q-wave <-0.3mV, or 4 times
of negative wave of Q-wave> voltage of R-wave and R'-wave, and/or Q-duration>40ms.
For leads V1, V2, voltage of Q-wave <-0.08mV and Q-duration>10ms.
ST elevation:
For leads I, II, III, avR, avL, avF, V4, V5, V6, the voltage of ST segment at 60ms
point >0.1mV, and for leads V1, V2, V3, the voltage at 60ms point >0.3mV.
ST slope elevation:
Voltage of ST segment at 20ms point>=voltage of J point, voltage at 40ms point >= the one at
20ms, voltage at 60ms point >= the one at 40ms, with change of ST elevation.

4.2 CTS introduction
The CTS computerized ECG conformance testing project was launched in 1989 by the
European Union. This project laid the foundation for computerized ECG conformance testing
service. Currently, about 20 types of waveform have been designed derived from the test signals
having an infinite length, these signals are part of the CTS-ECG test database, and have proven
their effectiveness in a series of official tests. According to the requirement of
IEC60601-2-51:2003 Medical electrical equipment - Part 2-51: Particular requirements for
safety, including essential performance, of recording and analysing single channel and
multichannel electrocardiograph Clause 50.101.1, 13 data (CAL05000, CAL10000, CAL15000,
CAL20000, CAL20002, CAL20100, CAL20110, CAL20160, CAL20200, CAL20210,
CAL20260, CAL20500, CAL30000) are used in the automated parameters verification for this
test.
