ABSTRACT:
The hemodynamic operation of certain heart disease patient can be improved using pressure regulated atrio-ventricular delay. The pressure regulated atrio-ventricular delay involves recording atrial activation and ventricle activation, identifying a maximum diastolic pressure, identifying a declination pressure, calculating a percent decrease, and adjusting atrio-ventricular delay. The declination pressure occurs at the beginning of an isovolumetric contraction. The percent decrease is calculated between the maximum diastolic pressure and the declination pressure. The atrio-ventricular delay is adjusted according to the percent decrease between the maximum diastolic pressure and the declination pressure.
