Guide for use: | CODE 1 Yes (New Q waves) Use this code where the follow-up ECG identifies Q waves >=0.03 seconds in width and >=1mm (0.1mV) in depth in at least 2 contiguous leads that were not seen on the initial ECG CODE 2 No (Pre-existing Q waves) Use this code where the follow-up ECG identifies Q waves >=0.03 seconds in width and >=1mm (0.1mV) in depth in at least 2 contiguous leads that were already seen on the initial ECG CODE 9 Not stated/inadequately described Includes unknown |

Collection methods: | Do not record whether the Q waves are new or not on the initial ECG. This data element should only be recorded for follow-up ECGs. |
Comments: | This data element identifies if new Q waves are present on the follow-up ECG. This information is valuable in coding transmural myocardial infarction. |
