Loss of R waves or poor R wave progression in leads V3 through V5 may indicate anterior MI (see Fig. 2-18). • R waves should increase in amplitude from V2 through V4. If R waves are present in leads V1 and V2 and are not present in V4 through V6, a diagnosis of anterolateral MI should be considered (see Fig.

Q waves may be up to 5 mm deep in several leads in individuals age <30. R waves V1: 0 to 15 mm, age 12 to 20 (see Table 2-3). 0 to 8 mm, age 20 to 30. 2 to 12 mm, age <30‡ (see Step 5, Fig. 2-16). ‡ ST segment Isoelectric or <1 mm elevation in limb leads and <1 mm in precordial leads except for normal variant (see Step 4, Fig. 2-12).
