1. A method, carried out with an implanted heart muscle stimulator associated with a heart of a patient, for treating a blood pressure disorder in the patient, the patient having a pretreatment systemic blood pressure corresponding to a pretreatment cardiac ejection profile, the method comprising:
determining an intrinsic temporal contraction sequence between an atrial chamber and a ventricular chamber of the heart; and
causing a different temporal contraction sequence between the atrial chamber and the ventricular chamber that differs from the intrinsic temporal contraction sequence, by stimulating the patient's heart with an electrical stimulus timed relative to the patient's cardiac ejection cycle,
wherein the different temporal contraction sequence alters the patient's cardiac ejection profile from the pretreatment cardiac ejection profile and reduces the patient's systemic blood pressure from the pretreatment systemic blood pressure.
