摘要： Implantable medical device for determination of timing for electrical shocks to the heart to determine shock strength necessary to defibrillate a fibrillating heart. The timing corresponds the window of most vulnerability in the heart, which occurs during the T-wave of a heartbeat. Using a derivatized T-wave representation, the timing of most vulnerability is determined by a center of the area method, peak amplitude method, width method, or other similar methods.

摘要： A medical device and associated method for monitoring a patient's heart rhythm sense cardiac events and detect a sudden change in the heart rhythm in response to the sensed cardiac events. Detecting the sudden change includes determining a variability of intervals between the sensed cardiac events and switching between a low variability mode of operation and a high variability mode of operation in response to the variability of intervals. During the low variability mode, detecting the sudden change includes detecting an increase in the rate of cardiac events. During the high variability mode, detecting the sudden change includes detecting a sudden decrease in the variability of the cardiac event intervals. A concerning cardiac rhythm is detected in response to detecting the sudden change.

摘要： A method and device for generating a template that includes determining whether there are consecutive events of a plurality of sensed events having first characteristics, and if a predetermined number of events of the plurality of sensed events subsequent to the consecutive events are identified as first selected events having second characteristics, the template is then generated from the first selected events.

摘要： A SubQ ICD that is entirely implantable subcutaneously with minimal surgical intrusion into the body of the patient and associated with subcutaneous leads provides distributed cardioversion- defibrillation sense and stimulation electrodes for delivery of cardioversion-defibrillation shock and pacing therapies across the heart when necessary. A level crossing detection system and process is implemented to detect noise, sinus rhythm and ventricular fibrillation in subcutaneous or body surface signals to deliver therapies as needed.

摘要： A method of generating a template in an implantable medical device for implantation within a patient, and a processor readable medium for performing the method, that includes generating a template corresponding to a supraventricular rhythm of the patient, determining whether the template is valid, and monitoring the template to determine whether the template is an accurate representation of the supraventricular rhythm. The template is created from non-paced R waves that are below a predetermined heart rate, and a statistical validation of the template is performed by evaluating the template based on matches against ongoing slow heart rhythm. The quality of the template is continuously monitored, similar to the statistical validation, with the exception that one thousand beats are evaluated and once more than thirty out of the last one hundred beats do not match the template within the threshold, an attempt is made to create a new template.

摘要： An implantable anti-tachyarrhythmia device which delivers anti-tachyarrhythmia therapies to a patient's heart in response to detection of tachyarrhythmias. The device defines first criteria indicating the presence of atrial tachycardia and second criteria indicating the presence of artrial fibrillation, and compares the time elapsed since the either the first or second criteria where initially met to a defined time duration. In response to the defined duration having passed and either of the first or second criteria being met, the device triggers delivery of an appropriate anti-tachyarrhythmia therapy. The timer is reset on detection of termination of artrial tachyarrhythmia, but not on failure of the first and second criteria to be met. The first and second criteria are defined such that they can not be concurrently met.
