“ECG Interpretive Abbreviations and Definitions (Figure 04)
ECG INTERPRETATION ABBREVIATION MEANINGS
The meanings of the codes are entered here for easy access. As can be seen by looking at the codes,
they are abbreviations of the typical cardiac diagnostic statement. This format was chosen to make the
need for this list almost non-existent. Obvious meanings are the intent for ease of use.
Special Note
Computer ECG analyses are an aid for ECG classification. Unconfirmed computer ECG analysis reports
SHOULD NOT be used for prescribing patient treatment or non-treatment without review by a qualified physician. No auto interpretation is completely reliable and physicians trained in ECG interpretation
should over read the ECG results.
Actual Reported Code/Statement Meanings:
The program takes as input the standard output of the CardioCard™ measurements program and outputs
the codes in a character string to be read as is.
On the ECG report and screen the following statement is made: "No automated analysis is completely
reliable and a physician should over read the results."
