ABSTRACT:
A method for sensing opening and closing of a tricuspid valve in a heart, for using those sensings to determine stroke volume, and for controlling pacing of a heart relative to changes in stroke volume, utilizing a pacing lead having a lead body and a pressure sensor mounted in the lead body, said method comprising the steps of: sensing the opening of the tricuspid valve during each heart cycle; sensing the closing of the tricuspid valve during each heart cycle; determining ejection time from the openings and closings of the tricuspid valve; calculating the change in ejection time, .DELTA.ET, from determinations of ejection time; calculating changes, in stroke volume, .DELTA.SV,; determining the required change in heart rate, .DELTA.R, relative to the change in stroke volume, .DELTA.SV,; and adjustng the pacing rate of a pacer relative to the required change in heart rate, .DELTA.R.
