Fig 1 Intraoperative lead II ECG tracing revealing marked phasic voltage variation depending on respiration; inspiration is indicated by Insp and expiration by Exp. Amplitude of each QRS complex in millivolt; QRS-max and QRS-min demonstrate maximum and minimum amplitude of the QRS complex, respectively.
