    摘要: A system and method which employs atrial discrimination algorithms to distinguish between different atrial arrhythmias occurring in a patient for selecting an optimal pacing therapy corresponding to the type of arrhythmia identified. In response to the detection of an atrial rate above the atrial tracking rate, discrimination criteria are applied to a detected atrial activity signal to distinguish between different types of supraventricular tachycardia, such as fast atrial flutter and other atrial flutter at a relatively slower rate, which may be occurring in the patient. The pacer is controlled to provide pacing therapy to a heart in a manner corresponding to the type of supraventricular tachycardia identified. The output of an atrial discrimination algorithm may be tracked and the trend thereof used to improve therapy timing. Various embodiments are disclosed herein.

    摘要: A system and method for providing pacing pulses after a cardioversion/defibrillation shock, where the pacing pulses have a pacing rate at an initial value. The pacing rate is decreased from the initial value until at least one intrinsic cardiac contraction is detected. In one embodiment, the pacing rate is decreased by a set amount after pacing a set number of cardiac cycles. Providing the set number of pacing pulses and decreasing the pacing rate by the set amount is then repeated until at least one intrinsic cardiac contraction is detected. An intrinsic cardiac rate is then determined from the at least one intrinsic cardiac contraction. The pacing rate is then increased and maintained to be above (i.e., greater than) the intrinsic cardiac rate.

    摘要: A system and method for identifying patients with asynchronous ventricular contractions due to abnormal electro-mechanical coupling and computing optimal pacing parameters for restoring synchronous contractions is disclosed. Such patients may have normal intra-ventricular and inter-ventricular conduction and cannot be identified from intrinsic conduction data alone such as QRS width. Techniques for computing optimal resynchronization pacing in order to compensate for abnormal electro-mechanical coupling are also described.

    摘要: Thousands of patients prone to irregular and sometimes life threatening heart rhythms have miniature heart-monitoring devices, such as defibrillators and cardioverters, implanted in their chests. These devices detect abnormal heart rhythms and automatically apply electrical therapy to restore normal heart function. Significant parts of these devices include the microprocessor and stored instructions, or algorithms, that govern how the devices interpret and react to electrical signals indicative of normal or abnormal heart rhythms. These algorithms generally use the time intervals between successive heart beats, or cardiac events, as a key factor in therapy decisions. To ensure accuracy of interval measurements, the inventor devised new methods for processing heart electrical signals, some of which ensure accurate interval measurements without unduly delaying therapy decisions or consuming significant battery power. One of these new methods detects an abnormal interval measurement and either disqualifies the abnormal interval from use in making therapy decisions or divides the abnormal interval into two or more other intervals, thereby facilitating identification and treatment of abnormal rhythmic conditions both efficiently and accurately.

    摘要: Thousands of patients prone to irregular and sometimes life threatening heart rhythms have miniature heart-monitoring devices, such as defibrillators and cardioverters, implanted in their chests. These devices detect onset of abnormal heart rhythms and automatically apply one or more shocks to their hearts. When properly sized and timed, the shocks restore normal heart function without human intervention. A critical part of these devices is the monitoring circuitry, which includes a microprocessor and stored instructions, or algorithms, that govern how the devices interpret and react to electrical signals indicative of abnormal heart rhythms. Often, the algorithms are too simple or too complex. Algorithms that are too simple lead to unnecessary shocking of the heart, while those that are too complex consume considerable battery power. Accordingly, the inventor devised a relatively simple and accurate algorithm for determining appropriate therapy options. One version of the algorithm computes three statistics—a range statistic, a minimum interval statistic, and a dispersion index—from a set of depolarization intervals. This algorithm defines the range statistic as the difference between largest and smallest depolarization intervals, the minimum interval as the smallest of the intervals, and the dispersion index as the standard deviation of the intervals. A scalar interval dispersion assessment, based on the three statistics, is then compared to a threshold to identify a rhythm as a flutter or fibrillation. The three statistics can also define a point in a three-dimensional space, with rhythm identification based on relative position of the point and a surface in the space.

    摘要: A pattern recognition system for use in an implantable cardioverter defibrillator that is capable of responding correctively to abnormal activity of the heart efficiently and specifically. The system of the present invention first establishes a template standard defining a median or other statistical measure of central tendency representing the point above which or below which actual sample values would be remarkable. Against the median are compared sampled values within a window having a pre-programmed length. For each cycle, a comparison is made between the template median and every value sampled within this pre-programmed window. Each cycle is then individually diagnosed such that if a selected value is above a particular pre-established threshold or below a particular pre-established threshold it will be classified as abnormal. A plurality of specific cycles must be classified abnormal in order for a final diagnosis to be made that the individual is experiencing arrhythmia. The system of the present invention is also capable of differentiating between types of abnormal and can classify the abnormal as being either ventricular tachycardia and ventricular fibrillation.
