🧭Axis: left
📈R-wave: normal progression
🔋Tall/small voltages: tall from BER
💔ST/T: pseudo lateral STEMI
= LA/LL reversal, BER

⏱️ HR: normal
⚡️Electrical: normal intervals
🧭Axis: normal
📈R-wave: normal
🔋Tall/small voltages: tall voltages, LVH
💔ST/T: secondary, discordant and proportional ST/T changes
= LVH, false positive STEMI

⏱️ HR: normal
⚡️Electrical: normal intervals
🧭Axis: borderline right
📈R-wave: normal
🔋Tall/small voltages: normal
💔ST/T: diffuse peaked T waves mildly pulling up ST segment, TWI in aVL concordant to QRS
= hyperkalemia (6.8), not STEMI
