Abstract: A medical device detects certain patient activity based on a programmable activity threshold and determines the duration of detected activity. The activity threshold may be optimized by obtaining first and second duration measurements for at least one of a first activity session and second activity session. The first duration measurement is based on the activity threshold, while the second duration measurement is based on actual start and stop of the activity session. An adjustment of the activity threshold is suggested based on a correspondence between the first duration measurement and the second duration measurement of the first activity session, or a correspondence between the first duration measurement and the second duration measurement of the second activity session. One of the first and second activities is non-significant activity expected to be undetected by the device, while the other of the two activities is low-level activity expected to be detected by the device.

Abstract: A heart rate monitor determines a heart rate for a primary subject by reducing noise and cross-talk from unwanted signal transmission sources. A set of pulse peaks having about the same amplitude and an amplitude greater than any other set of peaks are processed to determine a subject's heart rate, while data having an amplitude below that of the set of peaks is ignored. To retrieve enough data to determine a peak amplitude, the signal having heart rate information is sampled at a frequency higher than a normal sampling frequency. In some embodiments, if no data is received for a set time period which is in or above the range, the threshold resets to zero under an assumption that the primary subject is no longer within transmitting range.

The method offers an important option and capability for automatic, and/or manual, medical-treatment and/or pacemaker-control feedback, in real time, to improve a pacemaker patient's hemodynamic status, with such a patient's resulting hemodynamic-behavioral/status changes caused by such feedback being viewable immediately in the invention's produced output display.

Abstract: Techniques for determining whether artifacts are present in a cardiac electrogram are described. According to one example, a medical device senses a cardiac electrogram via electrodes. The medical device determines a derivative, e.g., a second order derivative, the electrogram. The medical device detects beats within the derivative, e.g., by comparing a rectified version of the derivative to one or more thresholds determined based on a maximum of the rectified derivative. The medical device determines whether the beats are periodic, and determines whether artifacts are present in the cardiac electrogram based on the determination of whether the beats are periodic. The medical device may further determine whether tachyarrhythmia is present and/or whether the cardiac rhythm of the patient is treatable based on the determination of whether the beats are periodic. For example, the medical device may determine that an electrogram is not treatable when the beats are periodic.

Abstract: A monitor provides a wireless signal with respective pulses, based on a heartbeat, repetitive physical movement, or other repetitive bodily action of a user. The pulses include longer duration pulses whose duration identifies the monitor, and distinguishes it from other monitors which may provide crosstalk interference. The longer duration pulses are interspersed among short duration pulses to reduce power consumption. A receiver unit processes the signal to determine a rate of the bodily action and provide a corresponding output. The receiver unit can operate in a baseline mode when crosstalk is not detected, where each pulse is used to determine the rate, or in a crosstalk mode when crosstalk is detected, where only the longer duration pulses are used to determine the rate. The receiver unit can synchronize with two or more consecutive longer duration pulses. The pulse duration can be fixed or determined dynamically, e.g., non-deterministically.

Abstract: Embodiments of the present invention relate to implantable systems, and method for use therein, that can detect T-wave alternans. In accordance with specific embodiments of the present invention, intrinsic premature contractions of the ventricles are detected, and at least one metric of T-waves is measured in a specified number of beats that follow each detected intrinsic premature contraction of the ventricles.
