Abstract:
A dual-chamber programmable pacemaker for enhancing cardiac performance of a patient suffering from hypertrophic obstructive cardiomyopathy, comprising:sensing means for sensing P-waves and R-waves, associated with natural atrial and ventricular contractions, respectively;means for storing a morphology signal for a naturally-conducted selected reference R-wave resulting from a natural ventricular depolarization;means for comparing the reference R-wave and a current R-wave and for verifying, based on such comparison, whether the current R-wave has the morphology of a naturally-conducted R-wave or is the result of an ectopic R-wave;processing means for adjusting an AV/PV interval in accordance with a predetermined strategy when it is verified that a current R-wave has the morphology of a selected reference R-wave and wherein the current R-wave is considered an ectopic R-wave when the current R-wave does not have the morphology of a selected reference R-wave.
