    摘要: An implantable cardiac stimulation device promotes intrinsic activity of a heart during demand pacing. The device increases the time and probability of an AV delay interval extension. The device may further increase the AV delay interval from a first extended AV delay interval to a longer second extended AV delay interval. The device may further encourage intrinsic AV conduction in patients with intact AV conduction by allowing multiple cycles during a search interval and multiple search times to further encourage intrinsic conduction from the atrium to the ventricle.

    摘要: A leadless implantable medical device (LIMD) includes a housing formed from a battery and an end cap. A proximal end of the end cap forms an LIMD proximal end and a distal end of the battery case forms an LIMD distal end. A non-conductive coupler mechanically secures a terminal end of the battery case to a mating end of the end cap, while maintaining the battery case and end cap electrically separated. A first electrode projects from the proximal end of the end cap. An intra-cardiac (IC) device extension projects from the distal end of the battery case. The extension includes a second electrode that is electrically connected to the battery case. The second electrode is located remote from the LIMD distal end. An electronics module is located within an internal cavity of the end cap and communicates with the first and second electrodes.

    摘要: Systems and methods are provided for detecting the orientation and/or movement of a patient having an implantable cardiac stimulation device and evaluating whether a change in the patient's cardiac activity can be at least in part due to a change in the patient's orientation. In one particular embodiment, signals from an orientation sensor and/or a pressure sensor are evaluated to determine static positional orientation of the patient and determine based on the static orientation whether the patient's cardiac activity is abnormal.

    摘要: A communication circuit of an implantable device is coupled to a power source (e.g., including a battery) upon receipt of a radiofrequency (RF) signal at the implantable device. A circuit that controls whether the communication circuit is to be coupled to the power source obtains its power from the received RF signal. Thus, the implantable device is able to perform RF signal monitoring (e.g., RF “sniffing”) without using battery power. Battery power is then used for subsequent communication operations after it has been determined that the implantable device is receiving RF signals (e.g., from a verified external device).

    摘要: Techniques are provided for use by an implantable medical device for optimizing the amount of ventricular dyssynchrony induced within a patient during protective pacing. In one example, the device analyzes intracardiac electrogram signals to detect an ischemic event within the heart. The device then delivers pacing stimulus in accordance with adjustable pacing parameters to induce ventricular dyssynchrony within the heart and adjusts the pacing parameters within a range of permissible values to achieve a preferred degree of ventricular dyssynchrony within the patient, so long as there is no significant reduction in left ventricular pumping functionality. Preferably, the pacing parameters are adjusted to maximize or otherwise optimize the degree of dyssynchrony induced within the patient. If a significant reduction in LV pumping functionality is detected, the dyssynchrony-inducing pacing is preferably suspended to avoid any deterioration in the condition of the heart. Techniques for detecting early onset of ischemia are also disclosed.

    摘要: A leadless intra-cardiac medical device (LIMD) includes multiple electrodes that allow for stimulation and sensing of the right ventricle (RV) and sensing of the right atrium (RA), even though it is entirely located in the RV. The LIMD includes a housing having a proximal end configured to engage local tissue in the local chamber and electrodes located at multiple locations along the housing. Sensing circuitry is configured to define a far field (FF) channel between a first combination of the electrodes to sense FF signals occurring in the adjacent chamber. The sensing circuitry is configured to define a near field (NF) channel between a second combination of the electrodes to sense NF signals occurring in the local chamber. A controller is configured to analyze the NF and FF signals to determine whether the NF and FF signals collectively indicate that a validated event of interest occurred in the adjacent chamber.
