ST-segment deviation in precordial leads. Quantitative ST-segment deviation in precordial leads (V1–6) is shown for the LMT, pLAD, and dLAD groups. Elevated ST-segment is shown in leads V1–3 in the LMT group and in leads V1–5 in the pLAD and dLAD groups. The magnitude of ST-segment elevation in leads V2–V5 is significantly higher in the pLAD group than in the LMT group. ST-segment elevation in leads V2–3 is notable among the precordial leads in all three groups. While ST-level gradually decreased to 0 mV for lead V6 in the pLAD and dLAD groups, it became negative in leads V5–6 in the LMT group
