ABSTRACT:
A system for monitoring a patient and treating the malfunctioning heart of the patient, either in an automatic mode or in a semiautomatic mode, includes means which derive at least one physiologic signal from or related to the patient's circulatory system representative of hemodynamic status. A feedback loop is implemented in a biventricular implant, in order to automatically or selectively optimize the patient's clinical hemodynamic status. Accordingly, the biventricular implant will be programmed to go through a series of AV delay, RV-LV timing and heart rate sequences which scan a preselected range of programmable values and apply those values to the patient's heart. Hemodynamic patient measurements will be recorded and preferably graphed over those applied values. The optimal AV delay, RV-LV timing sequence and pacing rate can then be selected either manually by a technician, physician or other operator, or automatically via the implant in order to secure the best personalized timing sequence for the patient. Preferably, the implant will also be capable of automatically recording hemodynamic information and adjusting intervals, in order to optimize hemodynamics without third party intervention. Also preferably, the automatic adjusting feature can be selectively programmed on or off using the device programmer, to control manual or automatic intervention.
