the changes of pulmonary capillary wedge pressure ( pcwp , mmhg ) , mean aortic pressure ( map , mmhg ) , cardiac output ( co , l/min ) , systemic vascular resistance ( svr , dynes/s/cm-5 ) , left ventricular stroke work index ( swi ) and mean systolic ejection rate ( mser , ml/s ) during sinus rhythm , atrial pacing and atrioventricular sequential pacing ( expressed in percentages of the individual values during ventricular pacing ) were : ( chart : see text ) the importance of atrial systole for cardiac performance was clearly demonstrated in dogs with normally compliant hearts .
