translate English to French: These gradients were increased by phenylephrine during both systole and diastole, noradrenaline and adrenaline during diastole and decreased by isoproterenol (systolic), left vagosympathetic trunk stimulation (diastolic), acetylcholine (systolic and diastolic), and adrenosine (diastolic).
La phényléphrine augmenta ces gradients durant la systole et la diastole, la noradrénaline et l'adrénaline les augmentèrent durant la diastole et l'isoprotérénol (systole), le tronc vagosympathique gauche (diastole), l'acétylcholine (systole et diastole) et l'adénosine (diastole) les diminuèrent.
