Abstract
The disclosure provides methods and apparatus of particular benefit for patients suffering heart failure including cardiac dysfunction, chronic HF, and the like and all variants thereof. According to the disclosure monitoring and therapy delivery for a wide variety of acute and chronic cardiac dysfunctions are described and depicted. Various forms of paired or coupled pacing therapy delivery provided alone or in combination with neurostimulation therapy delivered by both implantable and external apparatus, including defibrillation therapy are also provided herein.
Claims19
A physiologic atrial coordinated pacing method of therapy delivery for a patient having intact AV conduction, comprising the steps of:
- delivering electrical pace stimulus to an atrial chamber of a heart at a rate slightly above an intrinsic atrial rate;
- and
- delivering electrical stimulation to a ventricular chamber of the heart during a refractory and non-refractory period of said ventricular chamber.
A computer readable medium for storing executable instructions for performing a method of therapy delivery, comprising:
- instructions encoded for controlling delivery of electrical pace stimulus to an atrial chamber of a heart at a rate slightly above an intrinsic atrial rate;
- and
- instructions encoded for controlling delivery of electrical stimulation to a ventricular chamber of the heart during a refractory and non-refractory period of said ventricular chamber.
An apparatus for performing a method of therapy delivery, comprising:
- means for controlling delivery of electrical pace stimulus to an atrial chamber of a heart at a rate slightly above an intrinsic atrial rate;
- and
- means for controlling delivery of electrical stimulation to a ventricular chamber of the heart during a refractory and non-refractory period of said ventricular chamber.
