The MORGAM item ECG was derived from the local ECG records in GER-AUG as follows:

Local ECG finding optimally from four ECG recordings taken on different days:	MORGAM code: ECG (ECG findings):
Evolution of typical ECG findings of "transmural (Q wave) infarction": acute stage: evolution of ST segment elevation intermediate stage: decrease of ST elevation, terminal T wave inversion, R wave reduction or R wave loss, pathological Q wave subsequent stage: T wave inversion, pathological Q wave, normalization ST segment late stage: normalization of ST segment, persisting pathological Q wave	1 = definite ECG (Development of Q waves or evolution of an injury current which lasts more than one day)
Evolution of typical ECG findings of "non-transmural (non-Q wave) infarction": ST depression, T wave inversion, no pathological Q wave	2 = probable ECG (Evolution of repolarisation changes)
record not satisfying above criteria which nonetheless shows Q wave, ST segment depression, T wave inversion or ST segment elevation ventricular conduction defects or other disturbances ECG missing (for non-fatal events)	3 = ischaemic ECG (Records not satisfying above criteria which nonetheless shows Q-wave, ST segment depression, T wave inversion or ST segment elevation)
other ECG findings	4 = other ECG
not used	5 = uncodable ECG
not used	8 = irrelevant (EVTYPE 1 or 2)
insufficient data (for fatal events)	9 = insufficient data
