    摘要： A combination pacer/defibrillator is tailored for bradycardia patients. In one example, its shock-delivery specificity exceeds its sensitivity to shockable ventricular tachyarrhythmias. In another example, its specificity exceeds 95%, or 99%, or even 99.5%. Sensitivity is programmed to a high desired sensitivity value, but only if it can be done without decreasing the specificity below the desired specificity threshold value. This can be conceptualized as “avoiding at all costs” delivering false shocks, even at the expense of failing to deliver a shock to a treatable ventricular tachyarrhythmia. Specificity enhancements include, among other things, inhibiting shock delivery when the patient is breathing or not supine, using multiple channels or a high rate VT/VF detection threshold. The present pacer/defibrillator device could potentially save the lives of bradyarrhythmia patients who are not presently clinically indicated for a defibrillator/pacer, but who have an increased risk of sudden cardiac death due to one or more risk factors.

    摘要： A cross-chamber refractory period with an adaptively adjusted sensing threshold for use by a cardiac pacemaker is disclosed. In response to a cross-chamber event, the sensing threshold of a sensing channel is raised to an adaptively adjusted cross-chamber maximum refractory value. The cross-chamber maximum refractory value is derived from a peak amplitude measurement of the far-field signal resulting from the cross-chamber event.

    摘要： In an embodiment, an implantable medical device senses the heart rate of a patient by analyzing a cardiac signal of the patient. The device identifies an increase in the patient's sensed heart rate and determines whether noise in the cardiac signal exceeds a certain specified amount. Upon an increase in the sensed heart rate and a finding of noise in the cardiac signal, pacing is invoked in the patient at a normal rate or at a rate that is greater than an estimated intrinsic rate for that patient. The device continues to pace until the device determines that the noise in the cardiac signal has subsided.

    摘要： Methods and systems are directed to detecting atrial tachyarrhythmia. A plurality of A-A intervals is detected. The detected A-A intervals are selected and used to detect atrial tachyarrhythmia. Selecting A-A intervals may be based on determining that A-A intervals are qualified. Qualified A-A intervals may be determined if a duration of the particular A-A interval falls outside a predetermined duration range, for example. Qualified A-A intervals may also be determined based on events occurring between consecutively sensed atrial events of the particular A-A interval, and whether the duration of the particular A-A interval falls within the predetermined duration range, for example.
