His first electrocardiography (ECG) revealed a left bundle branch block (LBBB) (QRS complex width = 150 milliseconds) and sinus rhythm at a rate of 100 beats/minute (Figure 1). When the ILE infusion finished, the QRS complex was totally normal with width of 90 milliseconds (Figure 1).

(a) Initial (before ILE treatment) electrocardiography of Case 4 with accelerated junctional rhythm concomitant with bigeminy ventricular extrasystoles. (b) Electrocardiography of Case 4 after bolus administration of intravenous lipid emulsion (5th minute of ILE).

On the fifth minute of ILE infusion, it was observed that the frequency of VES decreased, and after finishing the ILE infusion (at 60th minute of treatment), the patient's rhythm was sinus at a rate of 74 beats/minute with no VES (Figure 4).
