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 blood pressure, the method comprising:

  • stimulating the heart, comprising causing to cause an atrium thereof to contract while a heart valve associated with the atrium is closed such that the atrial contraction distends the atrium, and the distending atrium results in reducing the patient'"'"'s blood pressure from the pretreatment blood pressure, by causing the atrium to contract at a time when pressure in a ventricle of the heart is about maximal so that active force of the atrial contraction increases atrial stretch above maximal passive atrial stretch caused by contraction of the ventricle.
