12-Lead ECG Waveforms
4x3 Format
By default, the 4x3 format prints 10 seconds of 12-lead ECG data in four staggered 2.5 second segments. Each 2.5
second segment displays the ECG reading for one set of three leads (see the following figure). You can configure the
report for either standard or Cabrera print formats. 1 mV calibration pulses are printed at the beginning of the report for
each data channel.
You can also configure the E Series unit to print 5, 7.5, or 10 seconds of ECG data for each set of leads. If you specify
a setting of 5, 7.5, or 10 seconds, the E Series unit prints data acquired during the same time period (5, 7.5, or 10
seconds) for each set of ECG leads; the E Series unit does not present the ECG data for the 5, 7.5, or 10 second
periods in the staggered time format that it uses for the 2.5 second setting. (The option applies only to real time 4x3
printouts and does not apply to reports or to the data stored to the data card.)
For information on how to change this default setting, see the E Series Configuration Guide.
Standard 12-lead printout is always in 4x3 format unless configured differently.
4x3 Median Complexes
This format prints a single median beat for each of the 12 leads. The median beat is computed by the 12SL algorithm
and is denoted by a squiggle at the end of each median lead. You can configure the report for either standard or
Cabrera print formats. 1 mV calibration pulses are printed at the beginning of the report for each data channel.
CAUTION
The 12SL analysis results can be affected by poor ECG data quality. If poor data quality is flagged by the system, the
interpretation statements are preceded by the statement, “Poor data quality, interpretation may be adversely
affected.” If this message prints, the analysis results may be invalid. Check for a LEADS OFF condition or other
sources of noise, correct the condition, and re-acquire. The ECG waveform should always be reviewed by a
physician to confirm any automatic interpretation.
