Short-Term Effects of Ketamine and Isoflurane on Left Ventricular Ejection Fraction in an Experimental Swine Model

Table 1

Animal Data. Ejection fraction (EF) measurements were made using standard echocardiography techniques. Pulse rate was recorded using standard ECG techniques and is presented as beats per minute. Pre-ket represents the starting values, Post-ket represents the values after ketamine was administered. Post-iso represents the values after isoflurane was administered. Postdefibrillation represents the values after induction of ventricular fibrillation and successful defibrillation. *Animals did not recover from ventricular fibrillation.
