CODE 1     ST-segment elevation >= 1 mm (0.1 mV) in >= 2 contiguous limb leads

ST-segment elevation indicates greater than or equal to 1 mm (0.1 mV) elevation in 2 or more contiguous limb leads.

CODE 2     ST-segment elevation >= 2 mm (0.2 mV) in  >= 2 contiguous chest leads

ST-segment elevation indicates greater than or equal to 2 mm (0.2 mV) elevation in 2 or more contiguous chest leads.

CODE 3     ST-segment depression >= 0.5 mm (0.05 mV) in >= 2 contiguous leads (includes reciprocal changes)

ST-segment depression of at least 0.5 mm (0.05 mV) in 2 or more contiguous leads (includes reciprocal changes).

CODE 4     T-wave inversion >= 1 mm (0.1 mV)

T-wave inversion of at least 1 mm (0.1 mV) including inverted T waves that are not indicative of acute MI.

CODE 5     Significant Q waves

Q waves refer to the presence of Q waves that are greater than or equal to 0.03 seconds in width and greater than or equal to 1 mm (0.1 mV) in depth in at least 2 contiguous leads.

CODE 6     Bundle branch block (BBB)

Bundle branch block pattern

CODE 7     Non-specific

Changes not meeting the above criteria.

CODE 8     No changes
