Abstract
Methods and systems for treating cardiac malfunction are disclosed, which according to an embodiment, may involve delivering a stimulation pattern of stimulation pulses to at least one cardiac chamber of a heart, with at least one of the stimulation pulses having a first stimulation setting configured to reduce at least one of end systolic volume (ESV) and end diastolic volume (EDV) in the heart and at least one of the stimulation pulses having a second stimulation setting different from the first stimulation setting, and with the stimulation pattern being configured to reduce the at least one of end systolic volume (ESV) and end diastolic volume (EDV) by at least 5% and maintain the at least one of end systolic volume (ESV) and end diastolic volume (EDV) on average at such reduced volume for a time period of at least one hour.
