there were significant differences ( p less than 0.001 ) between the ascending aorta and main pulmonary artery ( pa ) in the following blood flow parameters : peak flow velocity ( aorta = 92 cm/sec , pa = 63 cm/sec ) , average acceleration ( aorta = 940 cm/sec2 , pa = 396 cm/sec2 ) , acceleration time ( aorta = 98 msec , pa = 159 msec ) , deceleration time ( aorta = 197 msec , pa = 172 msec ) , average deceleration ( aorta = 473 cm/sec2 , pa = 356 cm/sec2 ) , and ejection time ( aorta = 294 msec , pa = 331 msec ) .
