although , in these hearts , acetyl glyceryl ether phosphorylcholine increased coronary resistance , which may have caused regional shunting and ischemia , it is unlikely that the negative inotropic effect of acetyl glyceryl ether phosphorylcholine was secondary to changes in coronary flow , since acetyl glyceryl ether phosphorylcholine also caused a dose-dependent negative inotropic effect in the electrically paced , noncoronary-perfused left atrium and right ventricular papillary muscle .
