  • Sympathetic stimulation for improved myocardial relaxation
    Patent number: 8498704
    Abstract: Described are methods and devices for improving diastolic function with electrostimulation in heart failure patients who exhibit relatively normal systolic function. Such patients are characterized by impaired myocardial relaxation during diastole that prevents adequate filling of the ventricles during diastole to thereby reduce cardiac output. An implantable device is described for effecting strategic and periodic stimulation of the sympathetic nervous system to elicit myocardial adrenergic activation for improved myocardial relaxation.
