摘要： An implantable medical device may be programmed by a programmer to apply a variety of ventricular fibrillation (VF) and ventricular tachycardia (VT) therapies, such as antitachycardia pacing (ATP) and cardioversion shocks. In general, the invention is directed to automatic activation of VF- and VT-related functions upon a single command. When a clinician interacts with the programmer to set VF therapies to active status, for example, VT therapies are automatically set to active status as well. Activation of several VF- and VT-related functions with a single command may save considerable time and may be beneficial to the patient. The invention further provides the freedom to customize the functions to the particular needs of a single patient or a group of patients.

摘要： The invention provides systems to prevent the delivery of anti-tachycardia pacing (ATP) following a defibrillation threshold (DFT) induction at implant. An algorithm that classifies episodes as induced or spontaneous is implemented, thereby enabling the ATP during charging feature to be operable only when spontaneous episodes are detected while temporarily suspending the ATP feature during the delivery of defibrillation shock after induction has been confirmed. Further, a user interface enables users to interact with an implantable medical device (IMD), particularly for setting a defibrillation threshold (DFT) or a 50 Hz burst from a single programmer screen. The user interface includes various functionalities to promote quick user access to parameters that govern diagnosis, therapy and other features of the IMD. A single screen enables the user to complete automatic and/or manual DFT inductions or a 50 Hz burst from a programmer interface while acquiring associated documentation from the same interface.

摘要： An implantable medical device (IMD) provides for adaptive timing of the delivery of cardioversion shocks. In particular, the invention IMD provides for an adaptive cardioversion synchronization delay with respect to a cardiac event, such as a sensed P-wave or R-wave. When cardioversion with a first synchronization delay fails to terminate a tachycardia, for example, cardioversion may be attempted again with a second synchronization delay. The IMD may keep track of whether each synchronization delay is effective in terminating the tachycardia, and may employ a historically effective synchronization delay when applying cardioversion therapy to treat a subsequent tachycardia episode.

摘要： A method and apparatus for inducing fibrillation in a patient, for example to verify the efficacy of a defibrillator system. In the disclosed embodiment, an implantable cardioverter-defibrillator has an output stage coupled via a plurality of leads to the patient's heart. When it is desired to induce fibrillation in the patient, the device's control circuitry initiates an output capacitor charging cycle and subsequent delivery of a multi-phase fibrillation inducing stimulus to the heart. The multiple phases of the stimulus reflect an incremental discharging of the output capacitor. In one embodiment, the stimulus has three phases, with the first two separated by a time interval equal to or slightly less than the patient's "vulnerability window," which is defined as the time period following a paced cardiac event during which repolarization of the cardiac muscle is occurring, rendering the heart susceptible to induced fibrillation. The final phase of the multi-phase waveform reflects an untruncated discharge of the remaining energy on the output capacitor.

摘要： The present invention outlines structures and methods for delivering a controllable amount of energy to a patient by automatically compensating for the load impedance detected by an implantable-cardioverter defibrillator (ICD). The invention employs high speed, switching power converter technology for the efficient generation of high energy, arbitrarywaveforms. Unlike a linear amplifier, switching power converters deliver high-energy waveforms with an efficiency that is independent of the size and amplitude of the desired waveform. An ICD that uses a switching power converter to deliver the desired energy to the patient stores the energy to be delivered in a storage capacitor. The converter then transforms this energy into an arbitrarily shaped output voltage-controlled or current-controlled waveform by switching the storage capacitor in and out of the output circuit at a high rate of speed. Preferably, the waveform comprises a ramp-type waveform.

摘要： A method for determining the far field radar signature of relatively large and complex objects, like a fighter aircraft, and the facility to provide the data for the method. The method includes reflecting different frequencies of near field radar energy off of an object while translating the object in a radial direction with respect to the radar so the resulting radar return includes a moving signal representative of the radar return of the object and a stationary return representative of environmental clutter. The environmental clutter and R 4 amplitude variations caused by signal strength variations due to the different overall reflection distances during translation are removed from the radar signal. Multipath reflections may also be removed. The resultant signal is transformed from a spherical wave to a cylindrical wave so that for objects having a major dimension that is presented to the radar with respect to a much smaller minor dimension at right angles thereto, the radar signature as determined by the method is almost identical to that obtainable at a far field radar range. In addition, the facility includes an electromagnetically shielded building, object translating devices with position feedback, object rotators, and a computer to perform the transformations.

摘要： A device and method to detect slow ventricular tachycardia, deliver anti-tachycardia pacing therapies, and delay a scheduled shock therapy if the ventricular tachycardia is not terminated or accelerated. Preferably, a shock therapy is delayed after verifying hemodynamic stability based on a hemodynamic sensor. After a shock is delayed, the device operates in a high alert mode for redetecting an accelerated tachycardia. Anti-tachycardia pacing therapies are repeated during the shock delay. A number of conditions can trigger delivery of the delayed shock therapy including a specified period of elapsed time; determination that the patient is likely to be asleep; detection of myocardial ischemia; detection of compromised hemodynamics, or detection of a substantially prone position or sudden change in position. A delayed shock therapy may be triggered by the patient and repeated delivery of painful shock therapies in patients that are not seriously compromised by a recurring, slow ventricular tachycardia is avoided.
