Medical devices and methods are used to treat cardiac dysfunction conditions which involve delivery of stimulation pulses in cardiac refractory periods in order to modulate an effective refractory period (ERP). Such devices and methods may be used in conjunction with or in place of other therapies, including increased cardiac contractility (ICC) therapy, post extrasystolic potentiation (PESP) therapy, and other therapies to achieve increased heart contractility, provide a safer and more effective regimen for the corresponding stimulation therapies, and reduce the risk of inducing an arrhythmia. |
