Abstract: Examples of systems, apparatuses, and methods for classification of electrocardiogram signals during cardiopulmonary resuscitation are described. An example system may include a defibrillator comprising an electrocardiogram analyzer. The electrocardiogram analyzer may be configured to apply a prediction modeling technique to an electrocardiogram signal to generate a predicted signal. The electrocardiogram signal may be captured from a patient undergoing cardiopulmonary resuscitation. The electrocardiogram analyzer may be further configured to subtract the predicted signal from the electrocardiogram signal to generate an error signal and to classify a rhythm of the electrocardiogram signal as one of a shockable rhythm or non-shockable based on the error signal. Decision parameters derived from the signals may be used in conjunction with a machine learning technique to classify the electrocardiogram signal.

Abstract: A method of determining a state of ventricular fibrillation from a waveform, includes: performing calculations on the Fourier transform of the waveform voltage values by using the quotient of the power in a high frequency band and of the power in a low frequency band; and determining the state of ventricular fibrillation by relating this ratio to the state of ventricular fibrillation. A defibrillation system for use in treatment of ventricular fibrillation includes at least one sensor to measure heart rhythm and at least one applicator to apply a defibrillation shock to a patient. The system further includes at least one processor which is adapted to calculate the ratio and also to obtain user input regarding survival of subgroups and average response times in the user's domain which allows calculation of an estimated maximum overall survival and selection of an optimum threshold for the ratio measure based on this maximum.

Abstract: A method of determining a state of ventricular fibrillation from waveform obtained at sampling rates and with filtering typical of current clinical devices, includes: performing calculations to produce the autocorrelation function of the measured ventricular fibrillation heart rhythm over a given range of lags; determining a first value related to the sum of the absolute values of the series of values forming the autocorrelation function over the given range of lags over the period of time; and determining the state of ventricular fibrillation by relating the first value or the logarithm of the first value to the state of ventricular fibrillation. A defibrillation system for use in treatment of ventricular fibrillation includes at least one sensor to measure heart rhythm and at least one applicator to apply a defibrillation shock to a patient.

Abstract: Systems and methods of targeting savings deposits are provided that enable a depositor, such as a customer of a financial institution, to save money for various purposes or goals. A financial institution can make offers for targeting savings deposits to its customers using a financial statement that the financial institution prepares and provides to its customers to report information related to customers' financial accounts. Such offers can be solicited or unsolicited and can include one or more targeted savings plans customized to meet customers' savings goals. The financial statement can be further used to enable customers to enroll in one or more targeted savings plans and to make savings transactions according to such plans. A credit card account statement can be used for such purposes such that customers can make targeted savings deposits along with making payments to credit card accounts.
