6.1.3 CCAA information on print preview/printout
The following CCAA information is given on the print preview/printout:
Manual entry before the start of the recording:
– Previous bypass or stenting (Yes/No)
– Time since chest pain started, in hours
Measured values:
• QRS width (averaged) [ms]
• ST score (averaged) [mm]
Assessed area of an occlusion:
– LCA (left coronary artery)
– LAD Prox (left anterior descending)
– LAD Dist (left anterior descending)
– RCA Prox (right coronary artery)
– RCA Dist (right coronary artery)
– LCX (left circumflex artery)
– 3V/LM narrowing (all three vessels or left main is affected)
Advice:
Recommendations based on the ST score and additional information:
• Transport to PCI centre
• Transport to nearest hospital
• Consider thrombolytic therapy if PCI centre is further away than 1.5 hours.
• Consider thrombolytic therapy
• No thrombolytic therapy
Information on LAD (left anterior descending)
For men under the age of 40 showing early repolarisation in the anterior leads,
false LAD diagnoses may occur.
