The interpretative statements pertaining to myocardial injury, infarct, and ischemia are derived
from measurements made on a signal-averaged beat (median beat) formed for each of
the 12 leads. The computerized ECG analysis selects three representative beats from the ten
seconds of data for each lead and averages the three beats to derive the median beat for that
lead. The ECG analysis is always based on ECG data obtained at 0.05–150 Hz frequency
response.
The analysis program is adjusted for patient age and sex. The 12-lead ECG interpretive
algorithm used by the LIFEPAK 15 monitor/defibrillator is the University of Glasgow 12-Lead
ECG Analysis Program. For more information, contact your Physio-Control representative for a

Possible Incorrect Treatment with Reperfusion
Therapy
Computerized ECG interpretive statements should not
be used to withhold or prescribe patient treatment
without review of the ECG data by qualified medical
personnel. All 12-lead ECG interpretation statements
provided by the LIFEPAK 15 monitor/defibrillator include
the printed message **UNCONFIRMED**. Always
confirm interpretive statements by over-reading the
ECG data.
