A flatline lead I results from bilateral arm-to-leg electrode exchange.
A flatline lead I plus P and T inversions in leads II, III, and aVF in a 31-year-old male patient suggested interchange of the arm and leg electrodes bilaterally. Prompt repetition of the ECG with corrected lead placement resulted in a normal ECG and prevented incorrect diagnosis, workup, and treatment.
