in spite of a marked replacement of n-6 fatty acids by n-3 fatty acids in cardiac sarcolemmal membranes in ml , there were no major differences in cardiovascular performance ( myocardial contractility , pre- and afterload , cardiac output and myocardial work ) between l and ml , when measured under baseline conditions and after the heart was stressed by atrial pacing ( heart rate : 160 beats/min ) .
