  • Publication number: 20180206753
    Abstract: Methods and systems are provided for discriminating rhythm patterns in cardiac activity. The method and system obtain cardiac activity data for multiple cardiac beats over a predetermined period of time. Multi-beat segments within the cardiac activity data exhibit different rhythm patterns of interest including fast and slow rhythm patterns. The method and system calculate a cardiac beats timing relation representative of intervals between the cardiac beats within a measurement window, wherein the measurement window is configured to overlap the corresponding multi-beat segment. The method and system designate the cardiac beats timing relation to have one of the rhythm patterns of interest based on a rate threshold, identifies when successive multi-beat segments exhibit rhythm patterns that transition between the fast and slow irregular rhythm patterns and records the irregular rhythm pattern transition in connection with the cardiac activity data.

  • Patent number: 7212857
    Abstract: An implantable cardiac device returns activations of corresponding right and left chambers of a heart to inter-chamber synchrony. A sensing circuit senses intracardiac signals representing right and left chamber ventricular electrical activity. A detector determines if a predetermined characteristic of the electrogram signals indicates dissociation of the corresponding right and left chambers. If dissociation is indicated, a pulse generator stimulates at least one of the corresponding chambers to restore inter-chamber synchrony.

  • Patent number: 7123967
    Abstract: An implantable neural stimulation device and method treats peripheral vascular disease of a patient. The device includes a pulse generator that provides stimulation pulses and an implantable lead that applies the stimulation pulses to neural tissue. An activity sensor senses activity level of the patient and a processor, responsive to the activity sensor, controls the provision of the stimulation pulses by the pulse generator. The processor causes the pulse generator to provide stimulation therapy any time the patient is active or when the patient is at rest. The processor further provides long term activity monitoring and closed loop control of neural tissue stimulation levels to adapt the stimulation therapy to changes in the patient's condition.

  • Patent number: 6970743
    Abstract: An implantable cardiac stimulation device provides long QT interval therapy for preventing abnormal ventricular activation-recovery time and ultimately ventricular arrhythmias. The device includes a sensing circuit that senses intracardiac activity of a heart and that generates electrical signals representing electrical activity of the heart. The device includes a physiologic sensor, such as body motion, or other diurnally varying sensor that reliably detects a diurnal state of the patient (i.e., not the QT interval itself). The device further includes a measuring circuit that measures a QT interval of the electrical signals, a control circuit that determines whether the QT interval is appropriate for the diurnal state, and a pulse generator that delivers pacing pulses to at least one chamber of the heart at a pacing rate when the QT Interval is pathologically too long.

  • Patent number: 6934583
    Abstract: Methods and apparatus for stimulating the right vagal nerve within a living body via positioning an electrode portion of a lead proximate to the portion of the vagus nerve where the right cardiac branch is located (e.g., near or within an azygos vein, or the superior vena cava near the opening of the azygos vein) and delivering an electrical signal to an electrode portion adapted to be implanted therein. Stimulation of the right vagus nerve and/or the cardiac branch thereof act to slow the atrial heart rate. Exemplary embodiments include deploying an expandable or self-oriented electrode (e.g., a basket, an electrode umbrella, and/or an electrode spiral electrode, electrode pairs, etc). Various dedicated and single-pass leads are disclosed, as well as, various electrodes, and stabilization means.

  • Patent number: 6922587
    Abstract: The progression or regression of left ventricular dysfunction (LVD) is automatically evaluated by a pacemaker or other implantable cardiac stimulation device by tracking changes in the resting sinus rate of the patient in which the device is implanted. The resting sinus rate is detected by first determining whether the patient is in a state of profound rest, such as sleep, then measuring the actual sinus rate during profound rest. Profound rest may be detected by using an activity variance sensor. An increase in the profound rest sinus rate over a period of several months indicates progression of LVD; whereas a decrease indicates regression. Appropriate LVD diagnostic information is recorded for subsequent review by a physician.

  • Publication number: 20040215253
    Abstract: An implantable cardiac stimulation device includes a system for terminating atrial accelerated arrhythmias of the heart. The system includes at least one lead including a plurality of electrodes adapted to define a plurality of atrial accelerated arrhythmia termination electrode configurations and an arrhythmia detector that detects an atrial tachyarrhythmia of the heart. The system further includes an electrode configuration selector that selects one of the plurality of electrode configurations for termination of the detected atrial tachyarrhythmia based upon a measure of at least one predetermined characteristic of the detected atrial accelerated arrhythmia. The system still further includes a therapy circuit that provides atrial tachyarrhythmia termination therapy to the selected electrode configuration.

  • Patent number: 6539259
    Abstract: A system and method are disclosed for automatically adjusting the sense amplifier sensitivity based on the sensing threshold of the undesired signals (i.e., far-field signals or undesired near-field signals). Specifically, R-wave sensitivity is based on the peak amplitude of the T-waves. Since the relationship between R-waves and T-waves is so repeatable, high confidence is achieved in setting the sensitivity above the T-wave sensing threshold. For atrial sensing, P-wave sensitivity is based on the sensing threshold of R-waves and/or T-waves, whichever is larger. Several embodiments are disclosed for determining the threshold for sensing the undesired signals, such as, double sensing until single sensing occurs, or otherwise detecting the peak amplitude of two or more cardiac signals.

  • Patent number: 6456879
    Abstract: An improved system and method for performing automatic capture/threshold detection in an implantable cardiac stimulation device or any device capable of stimulating some body organ or tissue. Prior art systems determine the cardiac tissue's stimulation threshold by detecting an evoked response to a fixed duration stimulation pulse and then increasing the stimulation pulse's amplitude by a predetermined safety margin value. Such systems are inherently based upon a belief that the chronaxie of a particular patient's strength-duration curve is essentially fixed and that the rheobase is variable. While this may be true at some times during the patient's life, e.g., during the acute phase after lead implantation absent drug effects, it is reported that drugs alone may alter the chronaxie and it is believed that other factors may also affect the chronaxie either alone or in combination with the rheobase.
