Abstract
A method and apparatus for modifying contractility of heart tissue. The method includes applying electrodes (34, 35, 38) to one or more sites in the heart (20) and making a determination at which of the sites, if any, to pace the heart. A parameter of an excitable tissue control (ETC) signal (50, 60) to be applied to the heart is set responsive to the determination, and the ETC signal is applied to at least one of the electrodes responsive to the parameter, so as to enhance contractility of the heart.
Claims32
A method for modifying contractility of heart tissue, comprising:
- applying electrodes to one or more sites in the heart;
- making a determination at which of the sites, if any, to pace the heart;
- setting a parameter of an excitable tissue control (ETC) signal to be applied to the heart responsive to the determination, and
- applying the ETC signal to at least one of the electrodes responsive to the parameter, so as to enhance contractility of the heart.
Apparatus for modifying contractility of heart tissue, comprising:
- one or more electrodes, which are applied at respective sites in the heart;
- and
- an electrical control unit, which makes a determination at which of the sites, if any, to pace the heart, and which sets a parameter of an excitable tissue control (ETC) signal to be applied to the heart responsive to the determination and applies the ETC stimulation to at least one of the electrodes responsive to the parameter, so as to enhance contractility of the heart.
