TABLE 1.

Arrhythmias in isolated perfused newborn hearts before and after exposure to either intralipid or propofol

Exposure	Sinus bradycardia	Heart block	AV dissociation with ventricular tachyarrhythmia	Ventricular tachycardia (without AV block)	Asystole
Pre‐exposure
Intralipid	0 (0)	0 (0)	0 (0)	0 (0)	0 (0)
Propofol	0 (0)	0 (0)	0 (0)	0 (0)	0 (0)
Post‐exposure
Intralipid	0 (0)	0 (0)	0 (0)	0 (0)	0 (0)
Propofol	8 (100)	7 (87.5)	7 (87.5)	1 (12.5)	1 (12.5)

Note: Values represent number of hearts. Percentages of hearts are shown in parentheses. Onset of arrhythmia was significantly associated with propofol exposure (p < 0.001 as assessed with Fisher's exact test). n = 6 intralipid‐exposed hearts, 8 propofol‐exposed hearts. AV indicates atrioventricular.

Abbreviation: AV indicates atrioventricular.
