摘要： An implantable device, such as a pacer, defibrillator, or other cardiac rhythm management device, can include a failsafe backup, such as a separate and independent safety core that can assume control over operation of the implantable device from a primary controller. In an example, the safety core can include a normal first safety core operating mode and a magnetic resonance imaging (MRI) second safety core operating mode that can provide different functionality from the normal first safety core operating mode.

摘要： An apparatus reliably detects a depolarization activation wave of the heart. The apparatus includes a sensor in electrical contact with the heart for sensing electrical activity of the heart and including an amplifier for amplifying the sensed electrical activity according to a variable gain and providing a signal corresponding to the depolarization activation wave. The apparatus further includes an output circuit coupled to the sensor for producing an electrical output corresponding to the depolarization activation wave sensed by the sensor when the signal exceeds a threshold. The apparatus still further includes a control circuit coupled to the sensor and the output circuit for varying at least one of the gain and the threshold to maintain a predetermined sense margin between the sensed electrical activity and the gain and the threshold.

摘要： A physiological instrument that includes a first component comprising an ECG monitor and a second component comprising a defibrillator. The second component may also include a pacemaker mounted to and electrically connected with the defibrillator. The first and second components may communicate with one another entirely by means of three optical communication channels, each channel including an optical signal path that includes windows through which the optical signals pass into and out of the components. The components may therefore operate in a fully integrated manner despite the fact that no electrical signal path exists between the components. The communication channels include a serial channel through which information concerning defibrillator and pacemaker operation is transmitted to the ECG monitor, a tri-state channel through which sync and ECG source information is transmitted from the ECG monitor to the defibrillator/pacemaker, and an analog channel through which either an ECG signal from the defibrillator electrodes or an eyeclose signal from the pacemaker may be transmitted to the ECG monitor. Data transmitted through the serial channel includes a power-on signal, such that turning on the defibrillator automatically turns on the ECG monitor. The tri-state channel is used to transmit sync information when the ECG monitor determines that the defibrillator is on and when the defibrillator electrodes have not been selected as the ECG signal source. When the defibrillator is off, the ECG monitor controls the supply of power to the defibrillator electrode preamplifier via the tri-state channel.

摘要： A nondefibrillating and nonfibrillation-inducing energy is delivered at a first internal thoracic location. A first resulting electrical signal is detected at a second internal thoracic location in or near a target region of a heart. A first defibrillation threshold is estimated using the nondefibrillating and nonfibrillation-inducing energy, the first resulting electrical signal, and a target electric field strength. The defibrillation threshold represents an energy that when delivered at the first internal thoracic location creates an electric field strength in the target region of the heart that meets or exceeds the target electric field strength.

摘要： An improved protection mechanism to protect from unintended execution of critical tasks operates, in one example embodiment, by receiving a request to start a task by a first process. The first process informs a second process of running an algorithm to verify the legitimacy of the received request to determine the need to start the task. The second process stores the information regarding the starting the algorithm by the first process. The first process runs the algorithm to verify the legitimacy of the received request, and conveys an outcome of the verification to the second process. The second process enables the start of the task by the first process based on the outcome of the verification and a checking of the stored information and the first process starts the task.

摘要： A pulse generator for use in a defibrillator provides cardioverting electrical energy to a heart through at least one lead having a pair of electrodes associated with the heart. Electrical energy is applied to the heart with a biphasic waveform having a first cardioverting phase and a second cardioverting phase. A crosspoint switch selectively couples a storage capacitor to the lead means. A master switch decouples the crosspoint switch from the storage capacitor while the crosspoint switch connections are changed between the first cardioverting phase and the second cardioverting phase. A control circuit provides independent control of the duration of both the first and second cardioverting phases.
