The present invention demonstrates that continuous hemodynamic monitoring can be used to identify the optimal A-V-delay and/or heart rate in a pacemaker- implanted patient suffering from heart failure. The A-V-delay determines the timing of late diastolic filling in relation to the onset of ventricular contraction and the duration of diastolic filling. An optimal tuning of the A- V-delay improves left ventricular filling pressures in patients with a DDD- programmed pacemaker and is particularly important in the presence of a compromised left ventricular function
L'invention concerne l'utilisation d'une surveillance hémodynamique en continu pour identifier le retard auriculoventriculaire optimal et/ou la fréquence cardiaque chez un patient souffrant d'insuffisance cardiaque et porteur d'un stimulateur cardiaque. Le retard auriculoventriculaire permet de déterminer le temps de remplissage télédiastolique par rapport au déclenchement de la contraction ventriculaire, et la durée du remplissage diastolique. Un accord optimal du retard auriculoventriculaire améliore la pression de remplissage du ventricule gauche chez les patients porteurs d'un stimulateur cardiaque à programme DDD, et est particulièrement important en cas de fonction ventriculaire gauche déficiente.
