摘要： A leadless intra-cardiac medical device senses cardiac activity from multiple chambers and applies cardiac stimulation to at least one cardiac chamber and/or generates a cardiac diagnostic indication. The leadless device may be implanted in a local cardiac chamber (e.g., the right ventricle) and detect near-field signals from that chamber as well as far-field signals from an adjacent chamber (e.g., the right atrium).

摘要： A process for determining whether the location of a stimulation electrode meets a selected heart performance criteria includes providing stimulation to the heart through the electrode and obtaining an impedance measurement during stimulation delivery using an impedance sensing vector formed by electrodes that do not include the stimulation electrode. The impedance measurements are processed, either alone or in combination with an electrogram, also obtained during stimulation, to obtain a measure of hemodynamic performance.

摘要： A method and apparatus for reducing the incidence of atrial arrhythmias by using an overdrive algorithm to determine the application of overdrive stimulation pulses to a patient's heart, e.g., in the atria. In a first aspect of the invention, the apparatus first determines an overdrive pacing rate and then applies pairs of temporally spaced (staggered) pacing pulses, i.e., primary and secondary pacing pulses, at the determined overdrive pacing rate. In a further aspect of the invention, the pairs of pacing pulses are applied at the overdrive pacing rate to multiple spatially spaced electrodes, i.e., electrodes distributed among multiple sites in a patient's heart, e.g., in the atria. In accordance with a first preferred embodiment, the electrodes may be distributed within a single atrium, e.g., the right atrium, of the patient's heart. Alternatively, a first electrode may be placed in the right atrium and a second electrode may be placed in the coronary sinus or the left atrium or multiple electrodes may be placed proximate to the left atrium. Furthermore, the invention relates to techniques for controlling overdrive pacing to multiple sites in a patient's heart so as to achieve and maintain a target degree of pacing and thus suppress tachycardias.

摘要： Techniques are described for overdrive pacing the heart using a pacemaker wherein the overdrive pacing rate only increases when at least two intrinsic beats are detected within a determined search period. In one specific technique, an increase in the pacing rate occurs only if two P-waves are detected within X cardiac cycles. In another specific technique, the overdrive pacing rate is increased only if at least two P-waves are detected within a block of N cardiac cycles. In both techniques, the overdrive pacing rate is decreased if no increase has occurred in the last Z cardiac cycles. By increasing the overdrive pacing rate only in response to detection of at least two P-waves within a determined number of cardiac cycles, an excessively high overdrive pacing rate is avoided. Other techniques are described for adaptively adjusting overdrive pacing parameters so as to achieve a determined target degree of pacing of, for example, 95% paced beats. By adaptively adjusting overdrive parameters to maintain a target degree of pacing, the average overdrive pacing rate is minimized while still maintaining a high number of paced beats, thereby reducing the risk of a tachyarrhythmia occurring within the patient.
